Introducing our 40 Micron Nylon Spray Gun Filter Element with 1/4 NPT Thread – a precision filtration solution designed for professional painters and industrial coating applications. Manufactured by Anping County Boli Hardware Wiremesh Products Factory (established 1998), we bring over two decades of expertise in wire mesh and filtration components. This filter element combines high-density nylon mesh with a standard 1/4 NPT thread, ensuring reliable particle removal and consistent fluid flow. Whether you're working with automotive paints, wood coatings, or industrial finishes, our filter delivers clean, contaminant-free material to your spray gun, reducing defects and rework.
Our factory specializes in custom wire mesh products, and this spray gun filter is engineered to meet the demanding needs of both small workshops and large-scale production lines. The 40 micron (400 mesh) rating effectively traps fine particles, dust, and impurities while allowing smooth paint passage. The 1/4 NPT male thread fits most standard spray gun inlets, making it a direct replacement for OEM filters. With options for white or customizable colors, we offer flexibility to suit your branding or identification needs.
Key Features & Technical Specifications
- 40 Micron Filtration: Captures particles down to 40 microns, ideal for fine finishing and high-gloss applications.

Frequently Asked Questions (FAQ)
-
Q: What is the advantage of a 40 micron filter compared to finer meshes?
A: 40 micron (400 mesh) strikes an excellent balance between filtration efficiency and flow rate. It removes fine particles that cause defects while allowing sufficient paint flow for fast application. For high-gloss finishes, it's a popular choice. -
Q: Can this filter be reused after cleaning?
A: Yes, the nylon mesh is durable and can be cleaned with appropriate solvents (e.g., acetone, thinner) or by backflushing. However, we recommend replacing after several uses if the mesh becomes stretched or damaged. -
Q: Is the 1/4 NPT thread compatible with all spray guns?
A: Most professional spray guns with a standard 1/4 NPT male or female inlet will accept this filter. It is a common size for gravity-feed and pressure-feed guns. For non-standard threads, we can provide custom adapters upon request. -
Q: What is the maximum operating pressure?
A: The filter is designed for typical paint spray pressures up to 3000 psi (206 bar). For higher pressures, please consult our technical team for reinforced options. -
Q: Can you produce filters with different micron ratings?
A: Absolutely. We manufacture custom mesh sizes from 10 to 500 micron. Just specify your requirement, and we can adjust the nylon mesh density accordingly. -
Q: How do I install the filter properly?
A: Screw the filter element into the spray gun's inlet (where the paint hose attaches) until snug. Do not overtighten. Ensure the filter is oriented correctly (flow direction is from the outside to the inside of the mesh). -
Q: Is the filter suitable for water-based paints?
A: Yes, nylon is chemically resistant to both water and solvent-based paints. However, after use with water-based paints, rinse the filter immediately with water to prevent drying and clogging. -
Q: What packaging options do you offer?
A: We offer standard packaging in poly bags (50 or 100 pieces per bag), blister packs, or custom branded boxes. Bulk packaging in cartons is also available for wholesale orders.
