Aramid filter bags, composed of the synthetic fiber known as aramid or Nomex, were pioneered in the 1960s and brought to market in 1967 by DuPont. In filtration applications, this material is primarily recognized as Meta Aramid. As a filtration media, it boasts the following key characteristics:
Beyond these filtration attributes, aramid filter bags present several other benefits, including:
Our aramid filter bags incorporate scrim-supported felt to boost filtration efficiency and prolong filter lifespan. Aokai's aramid filter bags see extensive use in industries such as asphalt, cement, as well as mining & metallurgy.

Q7. How do you choose material for a filter bag with good pricing?
Given that each filter has unique characteristics and parameters, the following factors are essential when selecting filter material for a dust collector filter bag:
(1) Working temperature
(2) Humidity
(3) Dust diameter
(4) The chemical properties of the gas
(5) The abrasiveness of the dust
(6) The mechanical parameters of the filter
Q8. When we manufacture the filter bags, please provide the following dimensions:
(1) The diameter or semi-perimeter of the filter bags
(2) The length of the filter bags
(3) The diameter and thickness of the CPO on the dust collector
(4) A drawing or sample of the filter bags
(5) The material composition of the filter bags
(6) The type of filter bags (round or flat), and the type of filter bag top (snap cuff or snap ring)
(7) The intended application of the filter bags: cement, asphalt, power plant, chemical, waste incineration, metallurgy, etc.
