Anti-static Polyester Fabric Air Filter Cartridge 150x300

The Anti-static Polyester Fabric Air Filter Cartridge is a specialized filtration solution designed for dust collection systems handling combustible or explosive dust. This kind of air filter delivers efficient particulate removal while eliminating the risk of static charge buildup that can lead to dangerous sparks and dust explosions .

During the filtration process, the friction between dust particles and filter media generates significant electrostatic charges. In environments with flammable dust—such as aluminum, sulfur, fine wood flour, or pharmaceutical powders—this static discharge can ignite an explosion . Our anti-static filter is engineered to safely dissipate this charge, drastically reducing this risk.

Below is the specification of the custom dust collector filter cartridge. If you are in need of this kind of filters, please send your inquiry to get a quote.

This Dust Collector Filter Cartridge serves critical filtration roles across numerous industries:

• * Cement Industry: Dust collection at crushers, conveyors, and packaging stations
  
  

• * Mining Operations: Ventilation and dust control at processing facilities
  
  

• * Woodworking: Collection of sawdust, sanding dust, and wood particles
  
  

• * Metalworking: Grinding dust, welding fume, and thermal cutting particulate removal
  
  

• * Chemical Processing: Dust control at material handling and packaging points
  
  

• * General Manufacturing: Industrial ventilation and process dust collection

Our engineering team can accurately recommend filter media and surface treatment solutions based on your dust characteristics, temperature, humidity, and other parameters, ensuring optimal filtration efficiency and lifespan.

* End-to-end quality control, reliable product delivery: We implement end-to-end quality monitoring from raw material intake and production to finished product testing. Every filter element undergoes rigorous inspection before leaving the factory to ensure perfect fit and reliable operation in your dust removal system.

* Global market validation, widespread trust: Our products are sold in over 120 countries worldwide and operate stably in industries such as cement, mining, woodworking, and metal processing. Twenty years of consistent quality is the cornerstone of our global customer trust.

* Response is fast and flexible, and customization is a one-stop solution: Whether it is non-standard size or special treatments such as flame retardancy, waterproofing, oil resistance, and antistatic properties, our R&D team can respond quickly and provide full-process customization services from prototyping to mass production.

Q1: Why do I need an anti-static filter cartridge?
A: If your dust collection system handles combustible dusts (aluminum, coal, wood flour, pharmaceuticals, sugar, plastics), static electricity generated by dust friction can create sparks that ignite the dust cloud, causing a catastrophic explosion. Anti-static filters prevent this by safely dissipating static charges to ground .

Q2: How does the anti-static property work?
A: The anti-static property is achieved by incorporating conductive micro-fibers (carbon or stainless steel) directly into the polyester filter media or applying a permanent anti-static coating . This creates a continuous conductive path, allowing static charges to be safely grounded through the filter housing.

Q3: How do I properly ground this filter cartridge?
A: Proper grounding requires three elements:

* Conductive Media: The filter media must be conductive (our anti-static media)

* Groundable End Caps: Metal end caps that contact the conductive media

* Housing Ground: The filter housing must have a grounding lug connected to earth ground
* Important: The anti-static property is useless if the charge has no path to escape—always check the connection between the filter, the cage, and the housing .

Q4: Can this filter be cleaned and reused?
A: Yes. These cartridges are designed for pulse-jet cleaning systems. The pleated design allows dust to release effectively during cleaning cycles. With proper maintenance, these filters provide long service life and can be cleaned repeatedly .

Q5: What customization options are available?

A: Almost everything:

• * Outer diameter and height (any size)

• * End cap style (open/closed, flange, three‑ear, six‑ear, threaded)

• * End cap material (galvanized carbon steel or stainless steel 304/316)

• * Filter media (polyester with conductive fibers, or conductive coating)

• * Surface treatments (PTFE membrane, oil‑proof, water‑proof, singeing, calendering)

• * Seal materials (chloroprene rubber, silicone, FKM)

• * Center skeleton material and open area
