Aramid filter bags are made of a synthetic fiber material called aramid, also known as Nomex. First developed in the 1960s by DuPont and commercially available since 1967, it is better known in filtration applications as Meta Aramid. This material boasts the following superb characteristics as a filtration media:
Beyond these filtration advantages, aramid filter bags also provide additional benefits, including:
- Prolonged Filter Bag Service Life
- Enhanced Cleaning Efficiency
- Reduced Energy Consumption
-

(3) Dust Particle Size
(4) Chemical Properties of the Gas
(5) Abrasiveness of the Dust
(6) Mechanical Parameters of the Filter
Q8. When we produce the filter bags, we require the following dimensions:
(1) Diameter of the filter bags or the semi-perimeter of the filter bags
(2) Length of the filter bags
(3) Diameter and thickness of the CPO on the dust collector
(4) Drawing or sample of the filter bags
(5) Material of the filter bags
(6) Type of the filter bags: round or flat; Type of the filter bag top: snap cuff or snap ring
