Paint Filters for Spray Guns Factory

Paint Filters for Spray Guns

High-performance coatings demand reliable filtration, and paint filters for spray guns from Anping CREMOTIVE Wire Mesh Products CO., LTD offer precision screening to maintain fluid consistency and prevent nozzle fouling. These in-line filters are installed directly on the fluid hose or gun inlet, capturing contaminants within the paint supply and ensuring uninterrupted spray patterns.

Design & Components

• Filter Cartridges: Cylindrical stainless steel mesh elements pressed into rigid polymer or metal cages. Standard diameters range from 12 mm to 25 mm, with lengths of 30 mm to 60 mm, fitting common quick-connect fittings.

• Filter Housings: Machined aluminum or stainless steel bodies with ¼″ to ⅜″ NPT or BSPT inlet/outlet threads. Clear polycarbonate sight windows (optional) allow visual monitoring of debris accumulation.

• Mounting Accessories: Swivel adapters, inline pressure gauges, and mounting brackets facilitate integration into fixed or portable spray systems.

Performance Characteristics

• Retention Efficiency: Mesh grades from 80 µm to 20 µm capture pigment clusters and agglomerates that exceed paint manufacturer recommendations for filter size.

• Pressure Handling: Rated for continuous service at up to 8 bar (116 psi), with burst ratings exceeding 24 bar (348 psi).

• Chemical Resistance: Housing seals and mesh coatings are compatible with solvents such as acetone, methyl ethyl ketone (MEK), and xylene.

Use Cases

• Automotive Assembly Lines: Prevent clogging in robotic spray guns applying primers and topcoats at high cycle rates.

• Industrial Robotics: Filter abrasive or pigment-loaded fluids in automated painting cells for appliances, machinery, and structural steel.

• Custom Finishing Shops: Provide interchangeable filter modules for quick adaptation to different paint products or gun types.

Cleaning & Replacement
Inline paint filters are designed for easy disassembly. Technicians can depressurize the line, unscrew the housing, and extract the cartridge for solvent flushing or ultrasonic cleaning. When mesh apertures show signs of distortion (visible under magnification) or flow rates drop by more than 10 % under rated pressure, replacement cartridges should be installed.

Technical Support & Documentation
Anping CREMOTIVE offers detailed installation guides, recommended filter grades based on typical paint viscosities (e.g., 15–20 s DIN cup), and performance data sheets. Filters are supplied with lot-numbered certificates verifying material composition, mesh count accuracy, and pressure-drop benchmarks.
