Gravity Spray Gun Cup Paint Filters

Gravity Spray Gun Cup Paint Filters

Gravity feed spray guns rely on small fluid cups mounted above the gun body. Anping CREMOTIVE Wire Mesh Products CO., LTD’s gravity spray gun cup paint filters are precision-cut discs that fit inside these cups, providing an initial filtration stage before fluid enters the gun’s fluid passages.

Filter Disc Design

• Dimensions: Standard diameters from 25 mm to 60 mm to fit common cup sizes (e.g., 125 cc, 600 cc).

• Mesh Grades: Stainless steel discs available in mesh counts from 60 (250 µm openings) down to 200 (75 µm openings), depending on coating type and particle size.

• Disc Frames: Perforated stainless steel support plates prevent collapse of the mesh under gravity and maintain disc flatness. Some models include a bonded PTFE mesh variant for extra chemical resistance.

Functional Advantages

• Reduced Nozzle Blockage: By removing larger particles and skin that form in the cup, these filters prevent downtime caused by cleaning gun fluid passages.

• Consistent Spray Quality: Even when spraying thicker materials—such as high-viscosity enamels or metallic finishes—cup filters maintain fluid uniformity feeding the nozzle.

• Easy Replacement: Technicians simply lift out the old disc, insert a clean one, and resume spraying in under one minute.

Applications

• Automotive Touch-Up and Spot Repair: Small-batch finishing benefits from in-cup filtration to avoid contaminant transfer in delicate color-match applications.

• Furniture and Cabinetry: Fine lacquers and waterborne finishes require mesh counts that balance flow with particle removal, typically 100 to 150 mesh.

• Arts & Crafts and Model Painting: Hobbyist gravity guns use smaller cup volumes; pre-cut filter packs maintain paint clarity for precise, small-scale work.

Care & Replacement Guidelines
Gravity cup filters should be checked each time paint is refilled. Discs showing visible clogs or bending should be replaced immediately. For multi-day projects, unused filters stored in solvent must be dried completely before reinstallation to avoid diluting new paint mixes.

Product Validation
Each filter disc lot is inspected for aperture size uniformity—maintaining ±5 % tolerance on mesh opening—and tested in a simulated gravity-feed gun to record flow-rate performance. Certificates of inspection accompany bulk orders.
