Table of Contents
1. What Are Flat Fan Nozzles?
Flat fan nozzles are spray nozzles designed to produce a thin, fan-shaped spray pattern.
Unlike full cone nozzles that distribute liquid in a circular footprint or hollow cone nozzles that form a ring-shaped pattern, flat fan nozzles direct liquid in a focused, elongated band across a defined coverage width. It typically ranges from 0° to 120° depending on nozzle design.
The spray pattern resembles a triangle or fan when viewed from the front.
Flat fan nozzles are engineered for applications that require:
- Uniform surface spraying
- Precise directional coverage
- Controlled liquid distribution
- Efficient cleaning and coating

These characteristics make them suitable for both low-pressure precision spraying and high-pressure industrial cleaning systems.
2. How Does Flat Fan Nozzle Work?
The working principle of a flat fan nozzle is relatively simple but highly effective.
Liquid enters the nozzle body under pressure and flows through a specially engineered orifice. Inside the nozzle, internal geometry reshapes the liquid stream into a thin sheet. As the liquid exits the opening, it spreads outward into a flat spray pattern.
Several design factors influence performance
① Nozzle Orifice Design
The orifice determines:
- Spray width
- Flow rate
- Spray uniformity
- Droplet size
Precision-machined openings help achieve stable spray performance.
② Operating Pressure
Pressure directly affects spray characteristics.
Higher pressure generally produces:
- Finer droplets
- Wider atomization
- Stronger spray impact
Lower pressure usually results in:
- Larger droplets
- Reduced atomization
- Lower spray force
③ Spray Angle
Flat fan nozzles are available in different spray angles.
Common options include:

High-pressure flat fan nozzles are used in dedicated parts washers to remove machining chips, lubricants, and surface contamination before downstream assembly or coating operations.
(3) Steel and Metals
Steel mills use high-pressure flat fan nozzles extensively for hydraulic descaling, as well as for spray cooling on runout tables and cooling beds.
The combination of high pressure (often 100 to 300 bar) and precisely angled flat fan spray ensures that scale is removed uniformly and that the steel cools at a controlled, consistent rate.
(4) Chemical Processing
Flat fan spray nozzles are used in reactor quenching, scrubber liquid distribution, spray drying preparation stages, and chemical coating lines.
Material compatibility is the dominant selection factor in this sector, and PVDF or 316L stainless steel nozzles are commonly specified.
(5) Agriculture
Boom sprayers for herbicide, insecticide, and fertilizer application represent the largest single application of flat fan nozzles by unit volume.
Standard flat fan and extended-range flat fan nozzles are mounted at regular intervals on the spray boom and operated at pressures calibrated to deliver the correct dose per unit area.
Air-induction flat fan spray nozzles have become increasingly important as regulators tighten drift restrictions on pesticide applications.
(6) Mining and Dust Suppression
Low-pressure flat fan nozzles and specialized flood nozzles are used to suppress airborne dust on conveyors, transfer points, and haul roads.
The wide, even spray sheet provides thorough wetting of large surfaces with minimal water consumption.

7. How to Choose the Right Flat Fan Nozzle: Step-by-Step
Selecting the right flat fan nozzle is essential for achieving optimal spray performance, process efficiency, and long service life.
The correct choice depends on several engineering factors, including application requirements, spray angle, operating pressure, flow rate, and material compatibility.
Step 1. Define the Application Requirements
The first step is understanding the spraying task.
Different applications demand different spray characteristics.
For example:
- High-pressure cleaning requires concentrated impact force.
- Surface coating requires uniform distribution and controlled droplet formation.
- Cooling systems prioritize consistent area coverage.
- Chemical spraying requires material compatibility and corrosion resistance.
Clearly defining the process objective helps narrow the nozzle selection.
Step 2. Select the Appropriate Spray Angle
Spray angle is one of the most important specifications because it determines coverage width, nozzle spacing, and spray impact.
Narrow Angles (15°–25°)
Narrow-angle flat fan nozzles produce concentrated, high-impact sprays.
Best suited for:
- High-pressure cleaning
- Industrial descaling
- Strip washing
- Surface preparation
Because the spray footprint is smaller, more nozzle positions are typically required.
Medium Angles (40°–65°)
Medium spray angles provide a balance between coverage and impact force.
Common applications include:
- Parts washing
- Degreasing
- Surface rinsing
- Coating systems
These angles are widely used in industrial spray bars.
Wide Angles (80°–110°)
Wide-angle nozzles maximize coverage area.
Typical applications include:
- Agricultural spraying
- Food processing washdown
- Gentle rinsing systems
- Large-area spray bars
The trade-off is a lower impact force per unit area.
Coverage Width Formula:
Coverage width can be estimated using:
Width = 2 × Distance × tan (Angle ÷ 2)
For example, at a spray distance of 300 mm:
Spray Angle | Approximate Coverage Width |
65° | ~390 mm |
110° | ~714 mm |
A larger angle increases coverage but reduces concentrated cleaning force.
Step 3. Match Flow Rate and Operating Pressure
Flow rate and pressure directly influence spray quality, droplet size, and cleaning performance.
When selecting a flat fan nozzle, consider:
- Required liquid consumption
- Desired spray impact
- Pump capacity
- System operating pressure
Generally:
- Low pressure produces larger droplets and gentler spraying.
- Higher pressure creates finer atomization and stronger impact force.
The nozzle must be matched to the system’s pressure capability to maintain consistent spray performance.
Step 4. Choose the Right Material
Material selection affects wear resistance, corrosion resistance, and nozzle lifespan.
Common material options include:
Brass
Economical and suitable for general-purpose water spraying and non-corrosive fluids.
Stainless Steel (303/304/316L)
The most common industrial choice.
- 303/304 Stainless Steel: Suitable for water, mild chemicals, and food applications.
- 316L Stainless Steel: Preferred for corrosive chemicals, chloride-containing fluids, food, and pharmaceutical environments.
