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 °C).
- 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.

Disadvantages
- Fair resistance to alkali

Applications
- Incinerator plants,
- Cement Kiln gas
- Lowacid coal fired boilers
- Asphalt/hot mix plants flue gas
- Minerals processing
- Soil remediation facilities
