Polytetrafluoroethylene Felt, 830 g/m2 (24.5 oz/yd2 )
Polytetrafluoroethylene Felt, 830 g/m2 (24.5 oz/yd2 )
Description
A 260°C (500°F) maximum service temperature, expanded polytetrafluoroethylene (PTFE) felt filter bag for use in pulse-jet style dust collectors with chemically aggressive operating conditions.
Features and benefits
-
Patented GORETM High Durability membrane technology provides an excellent combination of filtration efficiency, airflow, and durability
-
Chemically inert, providing the highest all-around chemical resistance and maximum bag life
-
Constructed using a woven RASTEX® scrim that provides excellent dimensional stability, extended flex life, and resistance to mechanical damage over the life of the filter
Applications
-
Chemicals processing: pharmaceutical and chemical process reactors that incorporate micronizing, grinding, and product collection in extreme environments that are chemically and thermally aggressive
-
Minerals processing: brick kilns
-
Metals processing: lead, copper, and other base metal production
-
Power generation and Incineration: medical and municipal waste incineration, as well as coal-fired boilers
