Long replacement cycles
Reduced maintenance downtime

Acrylic Filter Bags

Your Reliable Partner for Humid & Corrosive Conditions

Acrylic baghouse filter bags are more economical than other technical fabrics on the market. The fibers offer moder-ate chemical resistance but very good tensile strength. Since acrylic offers excellent hydrolysis resistance, it workswell in humid baghouse conditions with mild chemical attacks.

  • Chemical Resistance :Homopolymer acrylic acid needle-punched filter bags have good corrosion resistance and are resistant to organic agents, oxidants, inorganic acids and organic acids and will not hydrolyze.
  • Temperature Tolerance :Homopolymer acrylic filter bags can typically operate in temperatures up to 130°C .
  • Durability :They have good abrasion resistance and mechanical strength, ensuring a longer lifespan compared to other types of filter materials.
  • Low Energy Consumption :Homopolymer acrylic filter bags are soft in texture, require low cleaning pressure, have good vibration during cleaning, and are easy to remove dust, effectively reducing the consumption of compressed air, reducing maintenance, and saving operating costs.

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.
