Glassfiber High Temperature Pre filter


Introduction:

The high temperature Pre air filters are used before high temperature HEPA filters to filter the large dust, so it`s very important to maximize the HEPA filters service life.
The filter media is heat resistance long glass fiber, stainless 201 or 304 frame, stainless grille at the two side to hold the long glass fiber media.
Other frame as the choice: galvanized steel, aluminum alloy, aluminum aboard;
Thickness of the filter is 21mm, 46mm, 50mm, 69mm and so on.

 

Customized size available;
