INDUSTRY COMPONENT

Air Cap (for air-assisted models)

Air cap for air-assisted spray nozzles that controls atomization and spray pattern in industrial coating applications.

Component Specifications

Definition
A precision-engineered component in air-assisted spray nozzle assemblies that directs compressed air flow to atomize liquid coating materials and shape the spray pattern. It works in conjunction with the fluid nozzle to create fine droplets with controlled distribution, optimizing transfer efficiency and finish quality in industrial spraying operations.
Working Principle
The air cap receives compressed air through internal channels and directs it around the fluid stream exiting the fluid nozzle. This creates shear forces that break the liquid into fine droplets while shaping the spray pattern (fan, cone, or round). Adjustable air caps allow operators to modify atomization quality and pattern width by regulating air pressure and flow.
Materials
Stainless steel (AISI 303, 316), hardened tool steel, brass, or engineered plastics (PTFE, PEEK) for corrosion resistance and durability. Surface finishes typically 0.8-1.6 μm Ra for consistent airflow.
Technical Parameters
  • Weight 50-200g depending on material
  • Pattern Width 4-24 inches (10-61 cm) at 12" distance
  • Spray Pattern Fan, cone, or round
  • Air Inlet Size 1/4" NPT to 3/8" NPT
  • Fluid Capacity 0.1-2.0 GPM (0.4-7.6 L/min)
  • Air Pressure Range 20-80 psi (1.4-5.5 bar)
Standards
ISO 10625, DIN EN 13966-2

Frequently Asked Questions

What is the difference between air caps for air-assisted and airless spray systems?

Air-assisted air caps use compressed air to atomize fluid and shape patterns, while airless systems rely solely on hydraulic pressure. Air caps provide finer atomization but require compressed air supply.

How often should air caps be inspected and cleaned?

Inspect daily for clogging or wear. Clean with appropriate solvents after each shift. Replace when orifice wear exceeds 10% of original diameter or pattern becomes irregular.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
