Polyester Flange-Clamp Air Filter, 3-5 Micron Rating, 400 G/m2, With Rubber Seal Gasket, 10m/s Face Velocity
Product Spotlights
As an experienced manufacturer from Anping County Boli Hardware Wiremesh Products Factory, established in 1998, we are proud to introduce our Polyester Flange-Clamp Air Filter with a 3-5 micron rating and 400 g/m2 media density. This filter is engineered to deliver reliable particle capture in demanding industrial environments, backed by our annual export value of US$5-10 million and a global customer base across North America, Europe, Southeast Asia, and beyond. The integrated rubber seal gasket ensures a tight fit, preventing air bypass and maximizing filtration efficiency.
Our filter is designed for systems requiring a face velocity of up to 10 m/s, offering low resistance while maintaining high dust-holding capacity. The robust polyester media is chemically resistant and moisture-resistant, making it suitable for HVAC, paint booths, compressor intakes, and general ventilation. Each unit is manufactured with precision to ensure consistent performance and long service life.

Frequently Asked Questions:
-
Q: What is the standard thickness of this filter?
A: The media thickness is typically around 15-20 mm, but it can be customized upon request. Please provide your required dimensions. -
Q: Can this filter be washed and reused?
A: This is a disposable filter designed for single-use. Washing may damage the fibers and reduce efficiency. However, we offer washable versions if needed. -
Q: What is the maximum temperature tolerance?
A: The polyester media can withstand continuous operation up to 80°C. For higher temperatures, consider our glass fiber media options. -
Q: Do you offer samples before bulk order?
A: Yes, we provide free samples for evaluation. You only need to cover the shipping cost. Contact us for sample requests. -
Q: How do I choose the correct size flange?
A: Measure your existing duct or housing opening. Our flange-clamp design fits standard duct sizes, and we can also produce custom dimensions. -
Q: Is the rubber gasket replaceable?
A: The gasket is integrated into the flange and not replaceable separately. The entire filter unit is replaced when needed. -
Q: What is the expected service life?
A: Service life depends on dust load and operating conditions. Typically, it lasts 3-6 months in moderate environments. Regular monitoring is recommended. -
Q: Can this filter be used in explosive environments?
A: No, this standard polyester filter is not anti-static. For explosive environments, we recommend our conductive or anti-static filter series.
