Flat Fan Nozzles
We specialize in providing top-quality flat fan nozzles tailored to meet the demands of diverse industries. With advanced engineering and durable materials, our nozzles ensure long-lasting performance and optimal results in even the most challenging environments.
Flat Fan Nozzles Definition
Flat fan nozzles are specialized spray nozzles designed to emit liquids in a flat, even pattern across a wide area. These nozzles are highly versatile and are commonly employed in various industries due to their ability to deliver efficient coverage on large surfaces. The spray pattern they produce is characterized by a consistent width, making them ideal for applications that require uniform liquid distribution, such as cleaning, agriculture, painting, cooling and surface treatment.
How Do Flat Fan Nozzles Work?
Flat fan nozzles work by forcing liquid through an elliptical, trapezoidal, or rectangular orifice. As the liquid exits the nozzle, it forms a flattened, expanding sheet as opposed to a round spray.
The liquid sheet then breaks up into ligaments and droplets. But the elongated “blade-like” shape of the orifice keeps the spray flattened even as it disintegrates.
Internal Design and Components
Inside most industrial flat fan nozzles you’ll find these key components:
- Orifice: The exit hole where the liquid emerges is elongated to shape the fan. The orifice geometry defines spray angle, flow rate, and distribution pattern.
- Deflector Surface: Liquid impacts an internal sloped surface before exiting, which helps flatten and spread the sheet.
- Body: Houses internal components and connects to pipe thread fittings. Typically made of brass, stainless steel, or engineering plastic.
Some lightweight flat fan nozzles use external deflection instead. A solid stream hits an angled “spoon” to flatten before exiting the nozzle.
Advantages and Benefits of Flat Fan Nozzles
Flat fan nozzles are characterized by their distinct spray pattern, delivering a wide, fan-shaped stream of liquid. This design provides:
- Uniform Coverage: Ideal for applications requiring consistent liquid distribution.
- Versatility: Compatible with a wide range of fluids, including water, chemicals, and coatings.
- Efficiency: Reduces waste by targeting specific areas with precision.
- Customizable Spray Angles: Available in varying angles to suit different operational needs.
Applications of Flat Fan Nozzles
Surface Cleaning
High-pressure flat fans generate a cutting liquid blade for intense scrubbing action. Different fan angles concentrate impact force for varying needs. Wide fans up to 110° cover big areas while narrow 15-60° fans drill into tough buildup.
Line-Striping and Coating
Flat fan nozzles lay down an “even coat” of paint, sealant, oil, or release agent onto flat surfaces. Adjustable flat fan tips meter flow for precision striping jobs like roads, turf, aircraft, and precision instruments.
Paper Processing
Flat fans provide the wide coverage, precision edges, big flow rates and droplet control needed for water-based applications in paper mills, printers and packaging plants. Uses range from lacquer spraying to edge-dyeing for decorative tissue and cleaning huge calender rolls.
Vehicle Washing
Tunnel wash systems rely on rows of flat fan jets to blanket vehicles with high-pressure detergent solution. The sharp fan spray edges wrap around complex curves and deliver strong impact to all surfaces. After soaping, angled flat rinse fans wash away solvents without water spotting.
Factors That Affect Flat Fan Nozzle Performance
While simple in concept, many interrelated factors determine how a flat fan nozzle ultimately performs:
Inlet Pressure: Too little pressure causes uneven, drifting spray lines while excessive pressure yields a finely atomized round spray negating the purpose of using a flat fan nozzle.
Fluid Viscosity: Thicker fluids strain against nozzle passageways interfering with designed flow dynamics leading to abnormal spray behaviour. Restrict use of coatings, adhesives or oils to recommendations for that nozzle’s design.
Temperature: Hot/cold temperatures influence liquid viscosity throwing off calibrated nozzle performance. Consider heated spray systems for materials sensitive to thermal changes in viscosity.
Wear: External impacts and prolonged abrasion degrades precision-machined orifices and deflector surfaces changing spray distribution and impact profiles over time.
Clogs: Any unsuspended particulate contaminates can cling to orifice “lips” and deflector surfaces distorting spray patterns temporarily or permanently depending on material. Even tiny flecks warrant immediate inspection and cleaning to prevent permanent damage.
Off-Axis Alignment: Flat fan nozzles require precise orientation relative to targeted surfaces. Minor misalignments stir unpredictable results rapidly deteriorating optimal performance capabilities.
