Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer with over 25 years of experience since 1998. Our 304 Stainless Steel Sediment Filter 20 Micron 1" NPT Inlet 75 GPM Flow Rate is engineered to deliver high-efficiency particulate removal for demanding industrial and commercial applications. As a factory with annual export value exceeding US$5 million, we combine precision manufacturing with rigorous quality control to ensure each filter performs reliably under continuous high-flow conditions. This filter is the ideal solution for removing sand, rust, scale, and other suspended solids from water, protecting downstream equipment and improving system longevity.
Our sediment filter features a robust 304 stainless steel body and a fine 20-micron stainless steel mesh screen, offering excellent corrosion resistance and durability. The 1-inch NPT female inlet and outlet allow easy integration into existing piping systems, while the 75 GPM (283.9 L/min) flow capacity ensures minimal pressure drop even at high flow rates. Whether you need a pre-filter for reverse osmosis, a protection filter for pumps and valves, or a standalone sediment removal unit, this product delivers consistent performance.
Key Features & Technical Specifications
- Material: High-quality 304 stainless steel housing and filter screen – resistant to rust, chemicals, and high pressure.
- Filtration Precision: 20 micron nominal – effectively removes particles down to 20 microns (≈0.0008 inches).
- Connection: 1" NPT female threads on both inlet and outlet – standard U.S. pipe thread, widely compatible.
- Flow Capacity: Up to 75 GPM (283.9 L/min) – suitable for high-flow applications such as main line filtration.
- Max Working Pressure: 150 PSI (10.3 bar) – designed for typical municipal and well water pressures.
- Operating Temperature: 32°F to 140°F (0°C to 60°C) – covers most cold and hot water applications.
- Cleaning & Maintenance: The stainless steel mesh is washable and reusable – simply remove the screen and rinse with water. No replacement cartridges needed.
- Installation: Can be installed vertically or horizontally. Includes a drain port for easy flushing.
- Custom Options: Different mesh sizes (50, 100, 200 micron, etc.), custom thread types (BSP, NPT), and special coatings are available upon request.

Why choose this sediment filter? The 304 stainless steel construction ensures long service life even in harsh environments. Unlike plastic filters, it won’t crack under UV exposure or high pressure. The 20-micron screen captures fine sediments while allowing high flow, reducing the need for frequent cleaning. The 1" NPT connection matches standard pipes, and the 75 GPM capacity makes it ideal for whole-house filtration, agricultural irrigation, and industrial pre-filtration. Each unit is tested for pressure integrity before shipment.
Customer Benefits
- Cost Savings: Reusable screen eliminates recurring cartridge costs – just rinse and reuse.
- Low Maintenance: Simple design with only one moving part (the screen) – minimal downtime.
- Enhanced Equipment Protection: Removes abrasive particles that can damage pumps, valves, and irrigation emitters.
- Versatile Installation: Can be mounted in any orientation; includes a drain valve for easy backwashing.
- Eco-Friendly: No disposable filter media – reduces plastic waste.

Frequently Asked Questions (FAQ)
Q1: What is the actual filtration rating of this filter – absolute or nominal?
The 20 micron rating is nominal, meaning it will capture the majority of particles ≥20 microns. However, due to the woven mesh structure, it also traps some smaller particles. For absolute filtration, we can supply alternative mesh sizes or multistage configurations.
Q2: Can this filter be used for hot water up to 200°F?
The standard design is rated for 140°F maximum. For higher temperature applications, we can customize the filter with high-temperature seals (e.g., Viton) and a different gasket material. Please contact our sales team for details.
Q3: Does the filter come with a mounting bracket or pressure gauge?
No, the standard package includes the filter body and the stainless steel screen only. Optional accessories such as mounting brackets, pressure gauges, and unions can be supplied upon request.
Q4: How often should I clean the screen?
Cleaning frequency depends on water quality and flow rate. Under typical conditions with moderate sediment load, cleaning every 1–3 months is recommended. You can monitor the pressure drop across the filter – when it increases by 5–10 PSI, it’s time to clean.
Q5: Is this filter suitable for saltwater or brackish water?
304 stainless steel has good corrosion resistance but may be susceptible to pitting in high-chloride environments. For saltwater applications, we recommend upgrading to 316 stainless steel (available as a custom option).
Q6: What is the minimum order quantity (MOQ) for this filter?
Our MOQ is typically 50 pieces for standard models. For sample orders or lower quantities, please contact us to discuss feasibility. We aim to support both small trials and large-scale projects.
Q7: How do I install the filter – horizontal or vertical?
The filter can be installed in any orientation. However, we recommend installing it with the drain port facing downward for easy flushing. Use thread sealant (e.g., PTFE tape) on the NPT connections to prevent leaks.
Q8: Can I get a custom mesh size other than 20 micron?
Yes, we offer a wide range of mesh sizes from 50 micron to 800 micron and even finer like 10 micron. Custom sizes are available upon request with a short lead time. Please specify your requirement when ordering.
