The BHA ThermoPleat filter element is constructed from a patent-pending stiffening resin system with aramid and PPS (polyphenylene sulfide) media that can withstand operating temperatures as high as 375°F (191°C). BHA ThermoPleat filters are a direct replacement for standard filter bags and cages. Their shorter length keep the filter elements out of the inlet gas stream, reducing abrasion problems and providing for a larger drop-out area.

Unique high temperature filter media

The BHA ThermoPleat media is unlike other stiffened needle felts. GE's patent-pending stiffening resin system was developed specifically for endurance in high temperature environments. The substrate fabric maintains its excellent physical properties and dimensional stability. The media is unaffected by small amounts of water vapor at high temperatures and can withstand mild minerals, organic acids, and mild alkalis. It resists surface penetration of particulate, dramatically increasing efficiencies while operating at significantly lower differential pressures.

BHA ThermoPleat construction features
