Our filter bags are designed based on actual site conditions, not generic catalog assumptions. We help you select the right media to balance filtration efficiency, pressure drop, and service life.
Adding an ePTFE membrane to an aramid filter bag allows the membrane to act as the filter cake. Dust stays on the surface of the membrane and does not get entrained into the fibers of the filter bag, which lengthens the life of your filter bag. It also reduces wear and tear, lower maintenance costs, and energy costs due to easy dust cake release during the cleaning cycle.
Why Use Anti-static Needle Felt Filter Fabric?
Conductive fibers or stainless steel conductive materials are mixed into the chemical fibers used to produce needle felt to produce antistatic needle felt with excellent antistatic properties. The results of comparing antistatic dust filter bags with ordinary dust filter bags in terms of physical properties, charge and dust removal efficiency have confirmed the superiority of antistatic dust filter bags.
Anti-static Needle Felt
Prevent sparks. Prevent explosions. Protect your baghouse operation.
Anti-static needle felt filter fabric is specially designed for dust collection systems in environments where static electricity may cause explosions, such as coal dust, flour dust, and chemical powders.
By incorporating conductive fibers (carbon fiber or stainless steel fiber) into the base material, the fabric effectively dissipates static charges, ensuring safe and stable filtration performance.
- Excellent Anti-static Performance
Prevents spark generation and reduces explosion risk - High Filtration Efficiency
Captures fine particles with stable performance - Durable & Long Service Life
Strong tensile strength and abrasion resistance - Wide Temperature Resistance
Available in polyester, aramid, PPS, and other materials - Customizable Structure
Anti-static yarn, stripe, or grid conductive design
Polyester anti-static needle felt has a wide range of uses in industrial applications. It has the following advantages:
- Excellent antistatic performance: Polyester antistatic needle felt has good antistatic performance through special process treatment or adding antistatic materials. It can effectively prevent static electricity accumulation and discharge, and is suitable for industrial environments that require antistatic.
- Wear resistance and durability: Polyester needle felt is made of polyester fiber, which has excellent wear resistance and durability. It is not easy to wear or deform after long-term use, and is suitable for long-term work in high-intensity use environments.
- Strong chemical stability: Polyester has good chemical stability, good acid and alkali resistance, and is not easily corroded by chemical substances. It is suitable for filtration and separation in a variety of industrial environments.
