P84 High Temperature Needle Felt Dust Filter Bag
Product Item: P84 Tenperature Needle Felt 
Product Introduction: P84 needle felt has three main advantages
1.High temperature resistance 
The working temperature is 260 ℃,and it has great ability to deal with accidences. 
 
2.Excellent chemical resistance
Decades of years of incineration house practice has proved the value of P84 bags, especially for acid gas and alkali dust filtration and collection. 
 
3.Low converse washing pressure and great dust cleaning ability
P84 fiber is small dtex, which enlarges the advantage. The erose fiber cross section ensures the larges fiber surface area and provides large number of small openings. Because of this, the dust will be mainly retained on the surface of felt, so the felt will be easily cleaned up. The pressure drop will be very small.
P84 felt has been successfully used in asphalt factories, cement factories, incineration factories, and coal burning boilers, etc.
