P84 (Polymide) needle felt

P84 ®Felt filter bags provide a unique and cost effective solution for many tough industrial baghouse applications. Versatile and efficient, P84 ® usage ranges form minerals processing, low acid coal fired boilers , asphalt / hot mix plants, to soil remediation facilities.

P84 ®filters are needled into filtration quality felts to be sewn into filter bags suitable for use in pulse jet style baghouses. The unique tri-lobal fiber structure of P84 ® provides customers with high efficiency filtration, low pressure drop, and reduced cleaning energy.

P84 polymide needle felts are excellent high temperature filter media in terms of performance, generally surpassing the other standard media with the exception of PTFE.

P84 Fiber Features

1.Excellent steady under high temperature and resistance to acid,

P84 can operate continuously , under practical and low acid working conditions, at temperatures up to 500F(260 centigrade).

2.High filtration efficiency , high tensile strength

The complex cross sectional shapes create 30-90% more collection surface area when compared to round or oval shaped fibers.

1. Low back washing pressure, maximum flexibility

The unique tri-lobal fiber structure of P84 provides customers with high efficiency filtration, low pressure drop, and reduced cleaning energy.

4.Excellent dust cake release

P84 has irregular , tri-labal fibers that provide better collection efficiencies and enhanced dust cake release properties.

Disadvantages

Fair resistance to alkali
