Glass fiber needle punched felt
Glass fibre needle felt filter material is a kind of new-type high temperature filter ones with reasonable structure of
good performance . It is needled into felt with 100% glass fibre, having three-dimensional structure of high rate of space,
little obstruction, dust removal efficiency exceed fabric filter material up to 99.9%. Filter speed one time higher
than fabric filter material. It is suitable for black charcoal chemical industry, steel, metallurgy, coal-buring boiler,
the high-temperature exhaust gas of Refractory material and cement. It is suitable for bag filter of pulsing clear dust
and high-speed blowback . After drilled by the high temperature, long time corrosion , it has good performance and control
the dust polluted effectively, and can retrieve a little valuable grain products.

PET antistatic needle punched filter cloth
As we all know, normal technical dust, like chemical dust and coal dust, is often explosive or cause fire, when the concentration touches its explosion limit and meet the static. Therefore the filter material, which is used to make bags containing these dust, must be antistatic.
Besides the skill in producing the common needle punched felt, we also need to add conductive material into the raw filter cloth in order to make the product antistatic. These two types are both in our scope of products
Bringing in foreign advanced technology, we developed and produced the very filter cloth , dacron antistatic needle-punched felt filter cloth, to meet the demand of all walks of life..
The antistatic needle-punched felt and filter cloth are in the peak position in our country and have been tested by some institution in authority.
