Product Details

Non-woven dust filter needled felt

is used non-woven needle punched process to make fiber staggered,
space distribution uniform fine fiber cloth. the regular fiber: PE,
PP, Acrylic, Nomex, PPS, Fiberglass, P84,PTFE. With the heat
setting, singeing, water & oil dipping, or PTFE membrane on the
surface finish treatment, it makes the needle felt surface smooth,
and not easy to be blocked by dust.
The fiber in Filtration needle felt has the three-dimensional
structure. This structure is conducive to form the dust layer, dust collection
effect stable.

Its efficiency is higher than general woven filter material.The application of the felt is very extensive like cement, waste
incineration, power plant, coal burning boiler, foundry,
metallurgical industry, asphalt, pharmacy, food industry, with
strong resistance to chemical stability. It can filter normal temperature or high temperature gas, and the gas with acid
and alkali corrosive.
