Our industrial dust collector bags combine a multilayer needle-felt substrate with PTFE membrane lamination, delivering consistent filtration at 99.9% efficiency for particles ≥0.3 µm. Engineered for pulse-jet, reverse-air, and shaker-type collectors, these bags withstand continuous operation at temperatures up to 230 °C (446 °F) and maintain structural integrity under 2000 Pa differential pressure.
Zero Leaks
Seamless needle-felt design – 30% fewer bag failures vs. stitched alternatives.
01
Energy Savings
<1.5 kPa pressure drop cuts fan power costs by 15-20%.
02
Explosion-Safe
Anti-static coatings for metal/chemical dust.
03
Custom Fit
20+ size profiles & hybrid material layers (e.g., P84®+PTFE).
