It is based on Continuing fiberglass flat filter cloth. The difference between them is on: its abb yarn is made of bulked yarn partly or completely. As we all know,  yarn is puff and has covering power and good ventilation. So it can improve the ability of filing and reduce blocking. It s cleaning is beyond99.5% and speed in 0.6-0.8m/minite.      

Formula:

RH ： Add acid resistant material into the formula with silicon oil, pot lead and PTFE.

FQ ：Priority to silicon oil and PTFE.

PSi ：Priority to silicon oil, pot lead and PTFE.

 FS 2 ： Priority to PTFE.

　　 FCA ：Priority to waterproofing agent and silicon oil.

Usage:

It is mainly used in air cleaning and recovering value powder. Such as: cements, carbon black, and some other trades
