PTFE acupuncture filter felt is a more excellent performance non-woven filter material of new and high temperature. That is 100% 3D-5D PTFE curly fiber, by series of nonwoven craft in loosing, combing,

lapping and acupuncture , making dense acupuncture of micro pore

in three dimensions, such as high temperature setting, singing,

calendaring and coating process.

Thisfilter has three exclusive features:

Temperature resistance:

Working environment of 250°C, instant temperature of 300 °C.

Chemical property:

PTFE filter material has good acid alkali resistance, is applied in complex exhaust gas treatment.

Application: it is mainly used to purify harsh working condition dust air contain moist, acid, alkali and

oxide groups.
