Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with annual export value of US$5-10 million. Our 304 Stainless Steel Frame Polyester Flange-Clamp Air Filter is designed to deliver reliable performance in demanding pneumatic systems. Rated for 0.5 MPa pressure, this filter combines a durable stainless steel frame with high-quality polyester filter media, ensuring efficient removal of particulates and moisture from compressed air lines. Whether you need a standard size or a custom solution, our product is engineered to meet the rigorous requirements of industrial applications across North America, Europe, Asia, and beyond.
The filter features a robust flange-clamp connection that simplifies installation and maintenance. The 304 stainless steel frame offers excellent corrosion resistance, making it suitable for harsh environments including food processing, chemical plants, and offshore platforms. Polyester media provides high dirt-holding capacity and low pressure drop, extending service life and reducing energy costs. With a pressure rating of 0.5 MPa, this filter is ideal for medium-pressure compressed air systems, pneumatic tools, and automation equipment.
Key Features
- 304 Stainless Steel Frame – Resists rust and corrosion, ensuring long-term durability in wet or corrosive environments.
- Polyester Filter Media – High filtration efficiency (up to 99.9% at 5 micron, customizable) with low initial pressure drop.
- Flange-Clamp Design – Quick and tool-free element replacement; secure sealing prevents bypass leakage.
- 0.5 MPa Pressure Rating – Suitable for a wide range of pneumatic systems, including compressors, dryers, and air tools.
- Wide Temperature Range – Operates from -20°C to +80°C, accommodating various industrial conditions.

Detailed Product Description
The 304 Stainless Steel Frame Polyester Flange-Clamp Air Filter is a premium solution for compressed air filtration. The 304 stainless steel frame provides exceptional mechanical strength and corrosion resistance, ensuring the filter maintains its structural integrity even in wet, high-humidity, or chemically aggressive environments. The polyester filter media is pleated to maximize surface area, resulting in high dirt-holding capacity and longer service intervals compared to standard mesh filters. The flange-clamp connection allows for rapid installation and removal without special tools, reducing downtime during maintenance.
This filter is designed to remove solid particles, oil aerosols, and condensed water from compressed air streams, protecting downstream equipment such as valves, cylinders, tools, and instruments. With a pressure rating of 0.5 MPa, it is ideal for most industrial compressed air systems operating in the medium-pressure range. The filter can be used in series with coalescing filters or dryers for higher purity requirements. Polyester media is resistant to water and oil, maintaining efficiency even in wet conditions. Optional enhancements include differential pressure indicators, automatic drains, and custom micron ratings (e.g., 1, 3, 10, 25 micron).
Benefits for Your Business
- Reduced Downtime – Quick-change clamp design minimizes maintenance time; >99% of contaminants are captured, preventing equipment failures.
- Lower Operating Costs – Low initial pressure drop and high dirt-holding capacity reduce energy consumption (compressor load) and frequency of filter replacements.
- Enhanced Product Quality – Clean, dry compressed air improves the performance of pneumatic tools, prevents product spoilage in food/pharma, and extends machinery life.
- Durability in Harsh Environments – 304 stainless steel frame resists rust and corrosion; polyester media withstands moisture and oil without degradation.
- Global Compatibility – Flange-clamp connection is widely used in sanitary and industrial applications; available in inch and metric sizes to suit global equipment.

Frequently Asked Questions
Q1: What is the maximum operating pressure for this filter?
A: The filter is rated for 0.5 MPa (5 bar / 72.5 psi). For higher pressures, please contact us for custom solutions.
Q2: Can I use this filter for oil removal?
A: Yes, the polyester media is effective for removing oil aerosols and condensed water. For oil vapor removal, a coalescing filter or activated carbon filter may be needed in series.
Q3: What micron ratings are available?
A: Standard options include 5 micron, 10 micron, and 25 micron. Custom micron ratings (e.g., 1, 3, 20 micron) are available upon request.
Q4: How do I install the flange-clamp connection?
A: The filter is equipped with a tri-clamp (sanitary) flange. Simply align the filter with the corresponding flange on your pipeline, place the clamp over the joint, and tighten the thumbscrew or wing nut. No tools required.
Q5: Is the filter element replaceable?
A: Yes, the filter element (cartridge) is replaceable. The stainless steel frame is reusable. We offer replacement elements for all sizes.
Q6: What is the operating temperature range?
A: The filter can operate continuously from -20°C to +80°C (-4°F to +176°F). For higher temperatures, please inquire.
Q7: Do you provide samples or small orders?
A: Yes, we accept sample orders for testing. Minimum order quantity for production runs is negotiable. Contact our sales team for details.
Q8: Can you customize the filter for specific applications?
A: Absolutely. We offer custom sizes, connection types (e.g., NPT, BSP, flanged), and micron ratings. Please provide your requirements for a tailored solution.
