High Temperature Filter Elements

ThermoPleat high temperature filter elements provide superior quality and performance for upgrading and improving existing dust collection systems that operate at high temperatures. The ThermoPleat filter element is a pleated product constructed from a patent pending stiffening resin system with aramid and PPS (polyphenylene sulfide) media that can withstand operating temperatures as high as 191°C. ThermoPleat filters are a direct replacement for standard filter bags and cages.

Unique High Temperature Filter Media

The ThermoPleat media is unlike other stiffened needle felts. BHA's patent pending stiffening resin system was developed specifically for endurance in high temperature environments, where in these applications, 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.

ThermoPleast Construction Features

• Strong, heat-resistant media
• Wide open pleat spacing and shallow pleat depth
• High filtration efficiency
• Perforated metal inner core
• Metal top and bottom construction
• Customized lengths and diameters
• Customized pleat counts

Additional Features and Benefits

• Stiffened (aramid or PPS) media allows for higher temperature operating range
• Designed to eliminate filter bags and cages, reducing installation time
• Reduces air-to-cloth ratios dramatically
• Metal tops and snapband cuff assemblies are designed to fit most standard tubesheet holes
• Silicone top is available for bottom access bag cup/venturi designs
• Specialty finishes available
• Shorter length keeps the filter element out of the inlet gas stream, reducing abrasion problems and providing for a larger drop-out area
• Additional filtration area reduces operating differential pressure

Extreme Temperature Filter Elements

ThermoPleat EXT extreme temperature filter elements provide superior quality and performance for upgrading and improving existing dust collection systems that operate at extremely high temperatures. ThermoPleat EXT is a pleated product constructed from a patent pending stiffening resin system with fiberglass and other high temperature fibers along with high temperature potting compounds. Designed to operate in temperatures reaching as high as 232°C, ThermoPleat EXT filter elements provide significant additional filtration area in high temperature pulse-jet baghouses, and are a direct replacement for Nomex® or other filter bags and cages. (See above for Features, Benefits and Construction Features.) ThermoPleat filter elements allow for increased airflow in high temperature applications.
