PTFE Needlefelt 750 g/m2 (22 oz/yd2)
Description
A 218 °C (425 °F) maximum service temperature, PTFE felt filter with high temperature potting (gray) for use in pulse jet style dust collectors where high differential pressure, high cleaning pressures and chemical resistance are required due to aggressive chemistries, operating conditions and dust loading.
Features & Benefits
? Membrane
technology provides an excellent combination of filtration efficiency and dust
cake release.
? Polytetrafluoroethylene scrim offers superior chemical resistance, excellent
dimensional stability, and resistance
to mechanical damage over the life of the filter.
? Chemically inert providing the highest all-around chemical resistance and maximum life.
Applications
Working with High-corrosive & temperature gas,
Chemical,
Waster incineration,
Coal-fired boiler,
Non-ferrous metal
