P84 polyimide needlefelts are excellent high temperature filter media in terms of performance, generally surpassing the other standard media with the exception of PTFE.
P84 Fiber Features
Excellent steady under high temperature and resistance to acid
P84 can operate continuously, under practical and low acid working conditions, at temperatures up to 500 F(260).
High filtration efficiency, high tensile strengh
The complex cross sectional shapes create 30-90% more collection surface area when compared to round or oval shaped fibers.
Low back washing pressure, maximun flexibility
The unique tri-lobal fiber structure of P84 provides customers with high efficiency filtration, low pressure drop, and reduced cleaning energy.
Excellent dust cake release
P84 has irregular, tri-lobal fibers that provide better collection efficiencies and enhanced dust cake release properties.
