Product Description

P84 Filter Media

P84 (polyimide) needle felt filter cloth. P84 polyimide needlefelts are excellent high temperature filter media in terms of performance, generally surpassing other standard media with the exception of PTFE.

Key Features

Excellent stability under high temperature and resistance to acid
Can operate continuously at temperatures up to 500°F (260°C) in practical, low acid working conditions
High filtration efficiency and tensile strength
Complex cross-sectional shapes create 30-90% more collection surface area compared to round or oval fibers
Low back washing pressure with maximum flexibility
Unique tri-lobal fiber structure provides high efficiency filtration, low pressure drop, and reduced cleaning energy
Excellent dust cake release properties
Irregular, tri-lobal fibers offer better collection efficiencies and enhanced dust cake release

Applications

Incinerator plants
Cement Kiln gas
Low acid coal fired boilers
Asphalt/hot mix plants flue gas
Minerals processing
Soil remediation facilities
