Flat Fan Nozzle
Flat Fan Spray Nozzle
A flat fan nozzle delivers a straight, even spray across a moving surface, which is essential when a strip of material such as steel, a conveyor of gravel, or a row of parts must be uniformly treated. This CNSS flat fan nozzle range supports spray angles from 0° to 120° and flow rates from 0.39 to 3430 L/min at 3 bar, enabling a single series to serve both fine rinsing and heavy-duty washing applications. Threads are available in sizes from 1/8 inch to 3 inch in BSPT or NPT, and bodies are made from 303 stainless steel, brass, 316 stainless steel, PP, PVC, PVDF, or PTFE depending on the process environment.

Key Benefits
What This Nozzle Gives You
- One nozzle series covers both light rinsing and heavy washing duties with consistent spray geometry
- Tapered edge design allows adjacent nozzles to overlap without leaving dry or wet stripes
- Male and female thread options provide flexibility in fitting to existing headers
- Wide range of body materials enables use in corrosive, high temperature, or chemically aggressive environments
- Straight jet variant concentrates flow into a high impact line for targeted cleaning
- Free trial samples and 10 day sample lead time reduce risk before committing to a full order
Application Scenarios
Where It Is Installed
- Rinsing headers over conveyor belts where uniform water coverage is required across the full width
- Gas scrubbers and cooling towers where a continuous curtain of spray must cover the full duct cross-section
- Cooling and quenching lines where even heat transfer across a hot surface is critical
- Sand, coal, and gravel washing bars handling high flow at moderate pressure
- Parts washing cabinets where rotating fixtures pass through a fixed spray plane
Who It Is For
Buyers Who Specify It
- Plant engineers replacing worn spray bars on existing washing or rinsing lines
- Scrubber and gas cleaning system designers specifying nozzles by angle and flow
- Mining and quarry maintenance teams managing dust suppression and material washing
- OEM machine builders needing a consistent nozzle solution across multiple machine models
- Distributors stocking a range of nozzles for local industrial users
Problems It Solves
What It Fixes on the Line
- Uneven coverage that creates dry stripes between nozzles on a spray bar
- Mismatched thread standards on older plant requiring custom adapters
- Corrosion of brass nozzles in chemical or scrubbing service
- Overspray and water waste when the spray angle does not match the target width
- Extended downtime due to long lead times for replacement nozzles
Technical Features
How It Is Built
- One piece construction with no internal parts that can loosen or wear separately
- Tapered spray edges designed for overlapping installation without coverage gaps
- Fan and straight jet patterns available from the same body family
- Male and female connections allow the nozzle to be fitted in either orientation on a header
- Extra wide spray angles available for use in tight standoff spaces
Materials
Body Materials and Where Each One Suits
- 303 stainless steel for general washing and rinsing duty

Comparison
How It Compares With the Alternatives
| Full cone nozzle | A full cone covers a circular area, making it suitable for tank filling or gas cooling, while a flat fan is better when the target is a line or moving strip |
|---|---|
| Hollow cone nozzle | A hollow cone produces finer droplets in a ring pattern, ideal for gas washing, but it cannot deliver even coverage across a linear target |
| Spiral nozzle | A spiral nozzle handles solids better due to its external vane, but its conical spray pattern does not provide edge-to-edge coverage on a conveyor |
| Flat fan nozzle with filter | The filtered version protects the orifice in dirty water lines but requires periodic strainer cleaning |
Use Guide
Fitting and Running It
- Measure the target width and standoff distance before selecting a spray angle
- Overlap adjacent nozzles by about the width of one tapered edge to avoid dry stripes
- Align all nozzles on the header so their spray planes are in the same plane
- Match the thread standard BSPT or NPT to the existing header before ordering
- Use a strainer or filtered variant when spraying recirculated water
- Inspect the orifice for wear when coverage begins to appear uneven
Questions Buyers Ask
Flat Fan Spray Nozzle Questions
What spray angles and flow rates can you supply?
Spray angles range from 0° to 120° and flow rates from 0.39 to 3430 L/min at 3 bar. Provide the target width, standoff distance, and line pressure, and we will recommend the correct size code.
Which thread sizes and standards do you make?
Available from 1/8 inch to 3 inch in BSPT or NPT, with both male and female connections, so the nozzle can usually be fitted directly to an existing header without an adapter.
Which body material should I choose?
303 stainless steel for general washing, 316 stainless steel for chloride or chemical scrubbing environments, brass for plain water service, and PP, PVC, PVDF, or PTFE for acid, alkali, or solvent service.
Can I get a sample before placing a production order?
Yes. Trial samples can be sent free of charge and are typically ready within 10 days.
Do you accept small orders and OEM marking?
Yes. Small volume orders are accepted, and standard or non-standard nozzles can be made to your drawing under an OEM order.
What happens if a nozzle fails in service?
A 3 month quality guarantee is provided. Send us a photo of the failed nozzle and details of the operating conditions by email for assessment.
What are your payment terms?
The product listing states T/T 100% in advance. Send the model, quantity, and destination port by email, and we will confirm the payment terms for your order.
