As a trusted manufacturer from Anping County Boli Hardware Wiremesh Products Factory, established in 1998, we specialize in precision filtration solutions for demanding industrial applications. Our 100 Mesh Spray Gun Inlet Filter is crafted from 304 Stainless Steel with a 1/4" NPT thread and rated for 5000 PSI, designed to effectively prevent clogging in spray guns and paint systems. With over two decades of export experience and annual export values exceeding US$5 Million, we deliver reliable components that enhance equipment performance and reduce downtime.
This filter is engineered to provide consistent filtration of particles down to 150 microns (100 mesh), ensuring that only clean fluid reaches your spray nozzle. The 304 stainless steel construction offers excellent corrosion resistance and durability, even when used with water-based paints, solvents, or other aggressive media. The 1/4" NPT male thread is compatible with standard spray gun inlets and adapters, making installation straightforward.
Our manufacturing process follows strict quality control procedures, and each filter undergoes pressure testing to verify its 5000 PSI rating. The compact inline design minimizes pressure drop while maximizing filtration surface area, allowing for extended service intervals. Whether you are a professional painter, a maintenance technician, or a manufacturer of spray equipment, this filter offers a cost-effective solution to protect your investment.
Key Features & Benefits
- High-Pressure Rating: Rated for up to 5000 PSI, suitable for airless sprayers, high-pressure cleaning systems, and hydraulic applications.
- Precision Filtration: 100 mesh (150 micron) stainless steel wire mesh effectively traps debris, scale, and contaminants without restricting flow.
- Corrosion-Resistant Material: 304 stainless steel body and mesh resist rust, chemicals, and wear, ensuring long service life.
- Universal Thread Compatibility: 1/4" NPT male thread fits most spray guns, paint pots, and fluid lines (adapter may be required for some models).
- Easy Maintenance: The filter element can be removed and cleaned; simply rinse with solvent or replace if needed (replacement elements available separately).

The filter's 100 mesh stainless steel screen is formed from a tightly woven wire cloth that offers a balance between flow rate and particle capture. Larger particles such as sand, rust flakes, or dried paint chunks are effectively stopped, preventing nozzle tip wear and erratic spray patterns. This results in a more consistent finish, reduced material waste, and fewer interruptions during production.
Installation is simple: unscrew the existing inlet fitting on your spray gun, thread the filter onto the gun's inlet, then attach the hose to the filter's other end (if applicable). For systems with a 1/4" NPT female connection, the filter can be used directly. Always ensure thread sealant (e.g., PTFE tape) is applied to prevent leaks at high pressures. The filter can be oriented in any direction, making it suitable for both gravity-feed and siphon-feed setups.

We can also provide samples for evaluation before mass production. Our professional sales team is ready to assist with technical inquiries and customization requests.
Frequently Asked Questions
-
Q: What is the exact mesh size of this filter?
A: The filter uses a 100 mesh stainless steel screen, which corresponds to an opening size of approximately 150 microns. This is ideal for trapping fine particles while maintaining good flow. -
Q: Is the filter compatible with all spray guns?
A: It has a 1/4" NPT male thread, which is a common standard. However, many spray guns have a 1/4" NPT female inlet, so it will fit directly. If your gun has a different thread (e.g., 1/8" NPT or M14x1.5), you may need an adapter (available separately). -
Q: Can this filter be used for water-based paints or solvents?
A: Yes, 304 stainless steel is resistant to a wide range of chemicals, including water, alcohols, ketones, and mild acids. It is not recommended for strong acids or chlorides at high temperatures. -
Q: How do I clean the filter?
A: Remove the filter from the gun, rinse it with a suitable solvent (e.g., paint thinner, acetone) or use compressed air to blow debris out from the inside out. For stubborn clogs, soak in a cleaning solution. Do not use abrasive tools that could damage the mesh. -
Q: What is the maximum operating temperature?
A: The filter can handle temperatures from -20°C to +120°C (-4°F to 248°F). For higher temperature applications, please contact us for alternative materials. -
Q: Does this filter come with a warranty?
A: We offer a standard warranty against manufacturing defects. Please check with our sales team for detailed warranty terms, as they may vary by order quantity and region. -
Q: Can I use this filter for high-pressure water blasting?
A: The 5000 PSI rating makes it suitable for many water blasting applications, but ensure the thread size matches and the flow rate is sufficient. For continuous high-pressure water use, periodic inspection is recommended. -
Q: How often should I replace the filter?
A: Replacement frequency depends on the fluid cleanliness. For clean paint, the filter may last for many gallons. If you notice a drop in pressure or spray pattern deterioration, it's time to clean or replace the element. We offer replacement mesh elements separately.
