industrial filtration media | ptfe needlefetl
detailed

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
