The Anti-Static Polyester Fabric Air Filter Cartridge is a specialized filtration solution designed for dust collection systems handling combustible or explosive dust. With its customized dimensions, this air filter cartridge delivers high-capacity filtration for industrial-scale applications while eliminating the risk of static charge buildup that can lead to dangerous sparks and dust explosions .
Constructed from conductive polyester fabric media, this filter cartridge incorporates anti-static fibers throughout the media structure, providing surface resistivity of less than 10⁹ ohms. When combined with groundable metal end caps, the cartridge safely dissipates static electricity to the filter housing ground, preventing electrostatic discharge in environments handling fine powders such as coal dust, aluminum particles, flour, sugar, pharmaceuticals, and wood dust .

Q: Is an anti-static filter alone enough to prevent dust explosions?
A: No. The anti-static filter is a critical component, but it must be installed in a properly grounded dust collector system. The filter housing, ductwork, and all conductive parts must be bonded and grounded to a common earth point. The filter provides a conductive path to ground – it cannot work if the housing is not grounded.
Q: Can I use this filter for oily or sticky dust?
A: Standard anti-static polyester may blind with oil. For oily applications , we recommend oleophobic‑coated anti-static media – available upon request. Please specify your application when ordering.
Q: Can you manufacture this filter in other sizes or with custom end caps?
A: Absolutely. Huahang specializes in custom sizes. Provide your housing dimensions (OD, ID, length), end cap type (closed, open, flanged, threaded), and seal profile. We will produce a perfect fit.
