Question 1

How do I choose the right needle felt media for my industrial baghouse?

Accepted Answer

Selection depends on operating temperature, gas moisture content, chemical composition (acid/alkali), and dust explosiveness. Our B2B experts guide your engineering team to select PP, Polyester, Nomex, or PPS.

Question 2

What emission levels can your dust collection bags achieve?

Accepted Answer

With standard needle felts, we achieve emissions under 20 mg/Nm³. Utilizing our premium ePTFE (Teflon) membrane lamination, we can guarantee particulate emissions below 5 mg/Nm³.

Question 3

What is the difference between pulse-jet and reverse-air filter bags?

Accepted Answer

Pulse-jet bags are supported by internal wire cages and filter dust on the outside, while reverse-air bags are suspended with top hangers and capture dust on the inside.

Question 4

Do you offer anti-static dust collector bags?

Accepted Answer

Yes, we supply epitropic (conductive carbon fiber) and stainless-steel wire blended needle felts which prevent spark hazards in coal mills, wood plants, and flour processing facilities.

Question 5

Can your bags handle high temperatures over 200°C?

Accepted Answer

Yes. For high-temperature boiler and furnace gases, we manufacture dust collection bags from Nomex (Aramide), PPS (Ryton), P-84 (Polyimide), and woven Fiberglass.
