Industrial spray nozzles are available in different designs, each producing a specific spray pattern, droplet size, flow distribution, and impact level. Understanding the main spray nozzle types helps you select the right nozzle for cleaning, cooling, coating, dust suppression, tank cleaning, chemical processing, and other industrial applications.
The most common types of industrial spray nozzles include full cone, flat fan, hollow cone, solid stream, spiral, air atomizing, tank cleaning, spray drying, and other specialized designs. Each type is suited to different operating conditions and process requirements.
This guide explains the main types of spray nozzles, how they differ, where they are commonly used, and which factors should be considered when selecting a nozzle for an industrial spray system.

1. What Is a Spray Nozzle?
A spray nozzle is a precision-engineered component that controls how a liquid is discharged from a spray system. Depending on its internal design, a nozzle can control the spray pattern, flow rate, droplet size, spray angle, and impact characteristics.
Different spray nozzle types are designed for different operating requirements. For example, a flat fan nozzle produces a narrow sheet-like spray for surface coverage, while a full cone nozzle distributes liquid across a circular area. Hollow cone and air atomizing nozzles can produce finer droplets for applications where atomization and evaporation are important.
Spray nozzles are widely used in industrial processes such as:
- Cleaning and washing
- Cooling and quenching
- Coating and lubrication
- Dust suppression
- Gas scrubbing
- Tank and vessel cleaning
- Humidification
- Chemical processing
- Spray drying
The nozzle type should be selected according to the process objective, operating conditions, fluid properties, and required spray characteristics.
2. How Do Spray Nozzles Work?
A spray nozzle converts liquid pressure into a controlled spray by accelerating, redirecting, and distributing the fluid through a specially designed internal passage and outlet.
The nozzle’s internal geometry determines how the liquid leaves the nozzle and forms its spray. Depending on the design, the resulting spray may form a flat fan, full cone, hollow cone, solid stream, spiral pattern, or fine atomized mist.
Several operating factors influence nozzle performance, including:
- Operating pressure
- Flow rate
- Orifice size
- Liquid viscosity
- Liquid temperature
- Nozzle design
- Spray angle
These factors affect the resulting spray pattern, droplet size, coverage, and impact force.
For a detailed explanation of different nozzle spray patterns, see our dedicated spray pattern guide. For more information about droplet characteristics, see our guide to spray droplet size.
Understanding these basic principles makes it easier to compare different spray nozzle types and select the appropriate design for a specific application.
3. Main Types of Industrial Spray Nozzles
Industrial spray nozzles are classified into different types based on their internal mechanisms, spray patterns, and atomization methods. Each type produces a distinct combination of droplet size, spray angle, coverage shape, and impact force.
Spray Nozzle Type | Spray Pattern | Main Characteristic | Typical Applications |
Full Cone | Solid circular cone | Uniform coverage | Cooling, washing, dust suppression |
Flat Fan | Flat fan | Linear coverage and impact | Cleaning, rinsing, coating |
Hollow Cone | Hollow cone | Fine atomization | Gas cooling, humidification |
Solid Stream | Straight jet | High impact | Cleaning, descaling |
Spiral | Spiral / cone | Large free passage | Scrubbing, slurry spraying |
Air Atomizing | Fine mist / fan | Very fine droplets | Coating, lubrication |
Tank Cleaning | Rotating / 360° | Internal vessel coverage | Tank and vessel cleaning |
Spray Drying | Fine atomized spray | Controlled droplet size | Food, chemical, powder production |
Ultrasonic Atomizing | Ultra-fine mist | Extremely fine droplets | Humidification, specialty processes |
(1) Full Cone Nozzle — Uniform Area Coverage
Full cone nozzles produce a solid circular spray pattern in which liquid is distributed across the central area of the spray. Depending on the design, internal vanes, swirl chambers, or other flow-directing features are used to create the cone-shaped spray.
Typical characteristics:
- Solid circular spray pattern
- Relatively uniform area coverage
- Available in a wide range of flow rates and spray angles
- Suitable for many low- to medium-pressure applications
- Available in stainless steel, plastics, ceramics, and other materials
Common applications:
- Industrial cooling
- Gas scrubbing
- Dust suppression
- Washing and rinsing
- Chemical processing
- Quenching
Selection factors:
- Required flow rate
- Spray angle
- Operating pressure
- Desired coverage
- Fluid properties
- Nozzle material
For applications requiring a ring-shaped spray or finer atomization, a hollow cone design may be more appropriate.
(2) Flat Fan Nozzle — Linear Surface Coverage
Flat fan nozzles produce a sheet-like spray that spreads across a relatively narrow, elongated area. Their spray geometry makes them useful for applications where a surface or moving product needs to be covered across a defined width.
Flat fan nozzles are often installed in rows, with spray overlap used to achieve more uniform coverage across a larger surface.
Typical characteristics:
- Flat or fan-shaped spray
- Linear coverage
- Good suitability for surface spraying
- Available with different spray angles and flow capacities
- Can provide relatively concentrated impact for cleaning applications
Common applications:
- Conveyor washing
- Surface cleaning
- Rinsing
- Surface preparation
- Coating and lubrication
- Parts washing
Selection factors:
- Required spray width
- Spray angle
- Distance from the target
- Flow rate
- Operating pressure
- Required overlap between adjacent nozzles
Flat fan nozzles are particularly useful when the target is a flat surface, moving web, conveyor, or other area that requires controlled linear coverage.
(3) Hollow Cone Nozzle — Ring-Shaped Spray and Fine Atomization
Hollow cone nozzles produce a ring-shaped spray pattern in which most of the liquid is concentrated toward the outer portion of the spray. A swirl chamber or other internal flow arrangement is commonly used to create the rotating liquid motion needed to form the hollow cone.
Compared with many full cone designs operating under similar conditions, hollow cone nozzles can produce relatively fine droplets and are often used where atomization and gas-liquid contact are important
Typical characteristics:
- Hollow or ring-shaped spray pattern
- Relatively fine atomization
- Large surface area for gas-liquid interaction
- Available in different spray angles and flow capacities
- Suitable for cooling, humidification, and gas treatment
Common applications:
- Gas cooling
- Evaporative cooling
- Humidification
- Gas scrubbing
- Chemical processing
- Air treatment
Selection factors:
- Required droplet size
- Flow rate
- Operating pressure
- Spray angle
- Gas velocity
- Fluid properties
Because the spray is concentrated toward the perimeter, hollow cone nozzles should not be selected when uniform liquid distribution across the entire circular area is the primary requirement.
(4) Air Atomizing Nozzle — Fine Droplet Control
Air atomizing nozzles use compressed air or another gas together with the liquid to produce a finely atomized spray. Because the liquid and gas streams work together to break up the liquid, these nozzles can provide much finer droplet control than many conventional hydraulic spray nozzles.
Depending on the design, air atomizing nozzles can produce round, flat, or other specialized spray patterns.
Typical characteristics:
- Fine atomization
- Independent control of liquid and atomizing air in many designs
- Low liquid flow rates can be accommodated
- Suitable for applications requiring controlled droplet size
- Available in different spray patterns
Common applications:
- Precision coating
- Lubrication
- Painting
- Chemical spraying
- Humidification
- Fine mist applications
Selection factors:
- Required droplet size
- Liquid flow rate
- Liquid pressure
- Air pressure
- Air consumption
- Desired spray pattern
Air atomizing nozzles are generally selected when the required atomization cannot be achieved efficiently with a hydraulic nozzle alone.
(5) Spiral Nozzle — Wide-Angle Coverage with Large Free Passage
Spiral nozzles use a spiral-shaped deflector or passage to spread liquid into a wide spray pattern. Their open-flow design provides a relatively large free passage, making them useful for liquids containing suspended solids or particles.
Compared with nozzle designs that rely on small internal passages or swirl chambers, spiral nozzles can offer better resistance to clogging under suitable operating conditions.
Typical characteristics:
- Wide spray angle
- Large free passage
- Full cone or hollow cone configurations
- Suitable for particle-laden liquids
- Relatively simple construction
- Available for low- and medium-pressure applications
Common applications:
- Dust suppression
- Gas scrubbing
- Flue gas desulfurization
- Wastewater treatment
- Pulp and paper processing
- Slurry spraying
Selection factors:
- Particle concentration
- Required flow rate
- Spray angle
- Free passage requirement
- Operating pressure
- Fluid properties
Spiral nozzles are particularly useful when reliable liquid distribution and resistance to clogging are more important than very fine atomization.
(6) Solid Stream Nozzle — Concentrated High-Impact Jet
Solid stream nozzles produce a concentrated, coherent liquid jet rather than a wide spray pattern. Because the liquid is focused into a relatively small target area, these nozzles are commonly used when high impact or precise liquid delivery is required.
Typical characteristics:
- Narrow, concentrated jet
- High impact at the target
- Limited coverage compared with fan or cone patterns
- Suitable for focused cleaning and process applications
- Available for a wide range of flow rates and pressures
Common applications:
- High-pressure cleaning
- Descaling
- Removing stubborn deposits
- Equipment cleaning
- Jetting and washing
- Targeted process spraying
Selection factors:
- Required impact
- Target distance
- Flow rate
- Operating pressure
- Required cleaning width
- Fluid properties
A solid stream nozzle is generally selected when concentrated impact is more important than broad area coverage.
4. Spray Nozzle Types Comparison
Different spray nozzle types are suited to different process requirements. The table below provides a high-level comparison of common industrial nozzle families based on spray pattern, atomization characteristics, coverage, and typical applications.
The values and characteristics shown are general guidelines rather than universal specifications. Actual performance depends on nozzle design, operating pressure, flow rate, liquid properties, and other system conditions.
Nozzle Type | Spray Pattern | Atomization | Coverage / Delivery | Typical Applications | Main Selection Consideration |
Full Cone | Solid circular cone | Medium to coarse, depending on design | Broad, relatively uniform area coverage | Cooling, washing, dust suppression, gas scrubbing | Required coverage, flow rate, pressure |
Flat Fan | Flat fan or sheet | Fine to coarse, depending on design | Linear or rectangular coverage | Surface cleaning, rinsing, coating | Target width, spray angle, overlap |
Hollow Cone | Ring-shaped cone | Relatively fine atomization | Concentrated around the outer portion of the spray | Gas cooling, humidification, chemical processing | Droplet size, flow rate, gas-liquid interaction |
Solid Stream | Concentrated jet | Coherent stream | Focused target area | High-pressure cleaning, descaling, targeted washing | Impact requirement, distance, pressure |
Spiral | Wide-angle full or hollow cone | Generally coarse | Wide coverage with large free passage | Dust suppression, gas scrubbing, wastewater and slurry applications | Free passage, particle content, flow rate |
Air Atomizing | Fine mist, fan, or cone | Fine to very fine | Controlled, localized spray | Coating, lubrication, humidification, precision spraying | Droplet size, air pressure, liquid flow |
Tank Cleaning | Rotating or fixed multi-directional spray | Depends on nozzle design | Internal vessel coverage | Tank and vessel cleaning, CIP | Tank geometry, cleaning radius, pressure |
Spray Drying | Fine atomized cone or specialized pattern | Fine atomization | Controlled droplet distribution | Food, pharmaceutical, and chemical powder production | Feed properties, droplet size, drying conditions |
Ultrasonic Atomizing | Fine mist | Very fine atomization | Low-flow, localized mist | Humidification, coating, specialty processes | Required mist rate, droplet size, process conditions |
5. How to Choose Between Different Spray Nozzle Types?
Choosing a spray nozzle type should start with the process requirements rather than the nozzle catalog. The most suitable design depends on what the spray needs to accomplish, the target geometry, and the operating conditions.
Step 1. Define the Application
First, determine what the nozzle needs to do.
For example:
- Surface cleaning → Flat fan or solid stream
- Area cooling → Full cone
- Gas cooling or humidification → Hollow cone or air atomizing
- Dust suppression → Full cone, spiral, or fine mist designs
- Tank cleaning → Rotary or fixed tank cleaning nozzles
- Precision coating → Air atomizing
- Spray drying → Specialized atomizing nozzles
The application provides the starting point, but it should not be the only selection criterion.
Step 2. Select the Required Spray Pattern
Next, determine the shape and distribution of liquid required at the target.
- Flat fan → Linear or surface coverage
- Full cone → Filled circular coverage
- Hollow cone → Ring-shaped coverage and atomization
- Solid stream → Concentrated impact
- Spiral → Wide coverage with a relatively large free passage
- Fine mist → Fine atomization
Step 3. Determine Flow Rate and Operating Pressure
The nozzle must deliver the required flow at the available system pressure.
Before selecting a nozzle, identify:
- Required flow rate
- Available operating pressure
- Number of nozzles
- Pump capacity
- Required spray angle
Do not select a nozzle based on pressure or flow rate alone. These values need to be considered together with the required spray pattern and coverage.
Step 4. Consider Droplet Size
Droplet size can strongly affect spray performance.
Larger droplets are often preferred when impact, penetration, or reduced drift is important. Finer droplets may be required for coating, humidification, evaporation, or other atomization-sensitive processes.
Droplet size depends on nozzle design, operating pressure, liquid properties, and other operating conditions.
Step 5. Check the Fluid Properties
The liquid being sprayed can affect nozzle selection and service life.
Consider:
- Viscosity
- Temperature
- Corrosiveness
- Suspended solids
- Particle concentration
- Surface tension
For liquids containing solids or particles, designs with a larger free passage may be more suitable.
Step 6. Select the Nozzle Material
Finally, select a material compatible with the liquid and operating environment.
Common industrial nozzle materials include:
- Stainless steel
- Plastic
- Ceramic
- Carbide
- Other application-specific materials
Material selection should consider chemical compatibility, temperature, abrasion, and expected service life.
The right spray nozzle is therefore the result of matching the nozzle type, spray pattern, flow rate, pressure, droplet characteristics, fluid properties, and material to the actual process.

7. How to Read Spray Nozzle Codes?
Spray nozzle identification codes are used by manufacturers to describe product characteristics such as nozzle type, flow capacity, spray angle, connection size, or material. However, there is no single coding system used by every spray nozzle manufacturer.
For this reason, a nozzle code should always be interpreted according to the manufacturer’s product catalog or technical documentation.
A code may contain information such as:
- Nozzle type — for example, full cone, flat fan, or hollow cone
- Flow or capacity designation — may identify a specific flow rate or nozzle size
- Spray angle — may indicate the nominal spray angle
- Connection size — may identify the inlet connection
- Material — may identify stainless steel, plastic, ceramic, or another material
- Model or series number — may identify a specific product design
For example, a manufacturer may use a code such as FC-15-90-SS316Â to identify a particular full cone nozzle configuration. However, the meaning of each section depends on that manufacturer’s coding system and should not be assumed to be universal.
When replacing an existing nozzle, check the manufacturer’s catalog, technical drawing, flow-pressure data, material, connection size, and spray angle rather than relying on the code alone.
If the original code is unclear, provide the nozzle model, dimensions, operating conditions, and application requirements to the manufacturer or nozzle supplier for verification.
8. How to Choose the Right Spray Nozzle?
Selecting the right spray nozzle is not just about understanding different spray nozzle types. It’s about matching the nozzle to your specific process conditions. A well-chosen nozzle can significantly improve efficiency, reduce fluid consumption, and ensure consistent results.
Follow this step-by-step guide to choose the most suitable option.
- Step 1: Define the Application
Start by identifying the primary purpose of the spray system. The application determines which nozzle characteristics are most important.
For example:
- Surface cleaning → coverage and impact
- Tank cleaning → internal coverage and cleaning force
- Cooling → liquid distribution and heat transfer
- Dust suppression → droplet characteristics and coverage
- Coating → spray uniformity and droplet control
- Gas scrubbing → gas-liquid contact
- Spray drying → controlled atomization and droplet size
Avoid selecting a nozzle based only on the application name. The same application may require different nozzle types depending on pressure, flow rate, target geometry, fluid properties, and process conditions.
- Step 2: Select the Spray Pattern
Determine how the liquid needs to be distributed across the target.
Common spray patterns include:
- Full cone — filled circular coverage
- Flat fan — elongated or linear coverage
- Hollow cone — ring-shaped coverage with relatively fine atomization
- Solid stream — concentrated liquid jet
- Spiral — wide-angle spray with a relatively large free passage
- Fine mist — very small droplets for selected atomization applications
The required pattern depends on the target shape, spray distance, desired coverage, and process objective.
For a more detailed explanation of spray shapes and their characteristics, see our nozzle spray patterns guide.
- Step 3: Match Flow Rate and Operating Pressure
Select a nozzle that can provide the required flow rate at the pressure available in your spray system.
First determine:
- Required flow rate per nozzle
- Total system flow rate
- Available pump pressure
- Number of nozzles
- Pressure loss through the piping and fittings
For hydraulic spray nozzles, flow rate generally increases as operating pressure increases. However, the relationship varies with nozzle design and should be confirmed using the manufacturer’s flow-pressure data.
Do not select a nozzle based on pressure alone. A nozzle that operates at the available pressure may still provide insufficient or excessive flow for the process.
When comparing nozzle models, always check the manufacturer’s published performance data for the specific nozzle design.
- Step 4: Determine Droplet Size and Spray Angle
After establishing the required flow and pressure, consider the droplet size and spray angle needed at the target.
Droplet Size
Droplet size affects how the spray behaves after leaving the nozzle.
Larger droplets generally provide greater momentum and are often useful for cleaning or reducing drift.
Finer droplets provide greater surface area and may be useful for coating, humidification, evaporation, and selected dust-control applications.
Droplet size depends on nozzle design, operating pressure, liquid properties, and other operating conditions.
For more information, see our guide to spray droplet size.
Spray Angle
The nominal spray angle determines the potential coverage area at a given distance from the target.
When selecting a spray angle, consider:
- Target dimensions
- Nozzle-to-target distance
- Required overlap
- Number and arrangement of nozzles
- Desired coverage uniformity
A wider spray angle does not automatically provide better coverage. The actual coverage pattern must be evaluated at the installation distance.
- Step 5: Check Fluid and Material Compatibility
The liquid being sprayed can affect both nozzle performance and service life. Before selecting a nozzle, evaluate the physical and chemical properties of the fluid.
Consider:
- Viscosity — affects flow and atomization
- Temperature — affects material selection and fluid behavior
- Corrosiveness— affects chemical compatibility
- Suspended solids — affects clogging and wear
- Abrasiveness — affects nozzle wear
- Surface tension — can influence atomization
Then select a nozzle material suitable for the operating environment.
Common materials include:
- Stainless steel
- Brass
- Plastic
- Ceramic
- Carbide
- PTFE and other specialty materials
Material selection should consider corrosion resistance, abrasion resistance, temperature, chemical compatibility, and expected service life.
For abrasive or particle-laden liquids, a wear-resistant material and an appropriate internal passage may be more important than simply selecting a different spray pattern.
- Step 6: Verify Installation and Operating Conditions
Before finalizing the nozzle selection, confirm that the nozzle can be installed and operated correctly within the spray system.
Check:
- Connection size and thread type
- Installation orientation
- Available installation space
- Nozzle-to-target distance
- Operating temperature
- Operating pressure
- Pump capacity
- Piping configuration
- Required maintenance access
For systems using multiple nozzles, also check the nozzle arrangement and potential spray overlap. A nozzle that performs well individually may not provide uniform coverage when installed incorrectly or positioned at an unsuitable distance.
Finally, compare the selected nozzle with the manufacturer’s technical drawing, flow-pressure data, material specifications, and installation requirements before ordering.
Spray Nozzle Selection Checklist
Before choosing an industrial spray nozzle, confirm the following requirements:
Selection Factor | What to Determine |
Application | What does the spray need to accomplish? |
Spray pattern | Full cone, flat fan, hollow cone, solid stream, spiral, or another pattern? |
Flow rate | How much liquid must each nozzle deliver? |
Pressure | What pressure is available at the nozzle? |
Droplet size | Are coarse, medium, fine, or very fine droplets required? |
Spray angle | What coverage is required at the target distance? |
Fluid properties | What are the viscosity, temperature, solids, and chemical characteristics? |
Material | Which nozzle material provides suitable corrosion and wear resistance? |
Installation | What connection, orientation, and space requirements apply? |
Maintenance | How easily can the nozzle be inspected, cleaned, or replaced? |
A complete nozzle selection should consider these factors together rather than choosing a nozzle type from the application name alone.
9. Common Spray Nozzle Selection Mistakes
Choosing a spray nozzle based only on its name or spray pattern can lead to poor coverage, excessive flow, uneven spraying, or premature wear. The following mistakes are common when selecting an industrial spray nozzle.
- Choosing a Nozzle Based Only on the Application
An application such as cleaning, cooling, or dust suppression does not automatically determine one specific nozzle type.
The required spray pattern, flow rate, pressure, droplet size, fluid properties, and target geometry should also be considered.
- Ignoring Flow Rate and Pressure
A nozzle must provide the required flow at the pressure available in the system. Selecting a nozzle without checking its flow-pressure data can result in insufficient coverage or excessive liquid consumption.
- Selecting the Wrong Spray Pattern
A full cone, flat fan, hollow cone, and solid stream nozzle distribute liquid very differently.
For example, a solid stream may be appropriate for concentrated cleaning, while a flat fan may be more suitable for covering a wider surface.
- Focusing Only on Spray Angle
A nominal spray angle does not tell you the complete coverage performance.
Actual coverage depends on spray distance, nozzle arrangement, pressure, liquid properties, and the interaction between adjacent sprays.
- Ignoring Fluid Properties
Viscosity, temperature, suspended solids, abrasiveness, and chemical composition can all affect nozzle performance and service life.
A nozzle suitable for clean water may not be appropriate for an abrasive slurry or corrosive chemical.
- Selecting the Wrong Material
Nozzle material should be compatible with the liquid and operating environment.
Corrosion, abrasion, and temperature can significantly affect nozzle life if the material is not selected correctly.
- Using a Nozzle Outside Its Intended Operating Conditions
Even a suitable nozzle type may perform poorly when operated outside the manufacturer’s recommended pressure, temperature, flow, or installation conditions.
Always check the technical data for the specific nozzle model before installation.
- Replacing a Nozzle Without Checking System Requirements
Replacing an existing nozzle with one that has a different flow rate, spray angle, connection, or operating pressure can change the performance of the entire spray system.
When replacing a nozzle, compare the original and replacement specifications rather than matching the physical appearance alone.

Q3. What is the difference between a full cone and flat fan nozzle?
A full cone nozzle produces a filled circular spray pattern and is commonly used for area coverage. A flat fan nozzle produces an elongated, sheet-like spray and is commonly used for linear or surface coverage.
Q4. What is the difference between a full cone and hollow cone nozzle?
A full cone nozzle distributes liquid throughout the central area of a circular spray, while a hollow cone nozzle concentrates the spray around the outer portion of the cone. Hollow cone designs are often selected when relatively fine atomization or gas-liquid contact is required.
Q5. Which spray nozzle is best for cleaning?
There is no single nozzle type that is best for every cleaning application. Flat fan nozzles can provide controlled surface coverage, solid stream nozzles can provide concentrated impact, and tank cleaning nozzles are designed for cleaning vessel interiors. The appropriate choice depends on the target, contamination, pressure, flow rate, and required coverage.
Q6. How does pressure affect spray nozzle performance?
Operating pressure affects flow rate and can also influence spray pattern and droplet size, depending on the nozzle design. A nozzle should be operated within the manufacturer’s recommended pressure range rather than assuming that higher pressure always provides better performance.
Q7. How often should spray nozzles be replaced?
Replacement frequency depends on the nozzle material, liquid properties, operating conditions, and wear rate. Abrasive fluids and high-pressure operation can accelerate wear. Changes in flow rate, spray pattern, coverage, or pressure requirements can indicate that a nozzle should be inspected or replaced.
Q8. Can different spray nozzle types be used in the same system?
Yes, different nozzle types can be used in the same spray system when each nozzle is correctly selected for its specific function. However, flow rate, pressure, spray interaction, material, and installation arrangement should be evaluated to ensure that the complete system performs as intended.
12. Conclusion
Choosing the right spray nozzle starts with understanding the differences between nozzle types and matching those differences to the requirements of the application.
Full cone, flat fan, hollow cone, solid stream, spiral, air atomizing, tank cleaning, and other specialized nozzle designs each provide different spray characteristics. The final selection should consider the application, spray pattern, flow rate, operating pressure, droplet size, spray angle, fluid properties, material, and installation conditions.
If you are unsure which spray nozzle type is suitable for your process, provide your required flow rate, pressure, liquid properties, target application, and installation conditions. These details can be used to identify suitable nozzle designs and configurations.
