In modern industrial cleaning systems, nozzles are the core components that determine the cleaning effectiveness. Flat fan nozzles are widely used in various fields such as metal processing, electronic components, food processing, medical equipment, automotive manufacturing, and chemical cleaning due to their ability to achieve high impact, wide coverage, and uniform atomization under limited flow and pressure. Compared to other types of nozzles (such as solid cone, hollow cone, and spiral nozzles), flat fan nozzles have significant advantages in linear coverage, target impact force, and spray pattern control, making them the preferred choice for many automated cleaning devices.
1. Spray Shape and Atomization Characteristics
Flat fan nozzles have elliptical or serrated openings at the spray holes. After passing through controlled pressure differences, they form thin sheet-like fan-shaped liquid curtains that project linearly.
● The spray edges are sharp, suitable for precise coverage;
● Fluid distribution is trapezoidal or uniformly rectangular, with maximum pressure in the center, suitable for concentrated rinsing;
● They can cover a wider cleaning area without overlapping spray zones, which helps in system energy savings.
2. Balance Between Impact Force and Coverage Area
The larger the spray angle, the greater the coverage, but the impact force per unit area decreases. By optimizing pressure and angle, dynamic balance between cleaning intensity and spray width can be achieved according to different cleaning needs.
3. Customizable Structural Design
Some high-end fan nozzles offer diverse customization options:
● Eccentric spraying (suitable for irregular targets);
● Adjustable angle/rotational design (for multi-dimensional coverage);
● Multi-hole parallel design (to enhance system scrubbing efficiency);
● Air-assisted fan nozzles (improve atomization fineness, commonly used for degreasing and decarbonization cleaning).
1. Pretreatment and post-cleaning of metal parts
In the steel, die-casting, aluminum profile and other manufacturing industries, flat fan nozzles are often used for degreasing and rust removal before parts processing, as well as cooling and residue removal in the later stage.
2. Cleaning of electronic components and precision equipment
Flat fan nozzles are used in conjunction with ultrapure water systems and low-pressure control systems for cleaning PCBs, chip holders, lenses, etc. High uniformity, low flow, and no residue are required.
3. Clean belt cleaning in the food and pharmaceutical industries
Under the requirements of HACCP and GMP certification, food and pharmaceutical companies have high standards for the cleaning of clean equipment and conveying systems, and flat fan nozzles are widely used in CIP/SIP systems.
4. Automotive painting and pretreatment systems
Multiple pretreatments in the paint shop, such as water washing, pickling, and phosphating, all use flat fan nozzles to complete uniform spraying to prevent slag and retain the uniformity of the film layer.
5. Papermaking and printing machinery scraper area flushing
In high-speed paper machines and offset printing machines, flat fan nozzles are used to regularly flush the scraper area to remove accumulated ink and paper to ensure continuous operation.
parameters | Explain | Selection recommendations |
Spray angle | 15°–110°Control the spray width, commonly 15°–110° | If the space is narrow, choose within 30°; if wide coverage is required, choose more than 80° |
Jet pressure | Determine the degree of atomization and impact force | General industrial cleaning is done at 3–8 bar; intensive cleaning reaches up to 20 bar. |
traffic demand | Matched with the pump system, unit L/min | Must match the target flushing area and water source |
Material selection | Corrosion resistant, wear resistant, food compatible | Stainless steel, ceramic, PVDF, etc. |
Interface size | Matching piping system | Common sizes include 1/8", 1/4", 1/2" BSP/NPT |
Additional considerations: anti-drip structure, presence or absence of filter, quick-release design, and ease of replacement of nozzle blades.
Flat fan nozzles are crucial components in industrial cleaning, directly affecting the system's operational efficiency, energy consumption, and cleaning quality. From selection, application to daily maintenance, companies need to develop optimal configurations based on operating conditions, fluid characteristics, and production pace.
