Product Category Description:

These economical filters are suitable for high temperature and hot gas air monitoring applications. Filters consist of heat-resistant, pure borosilicate glass fibers with moisture-resistant fluorocarbon (tetrafluoroethylene, TFE) coating. During air sampling, moisture variations in air or gases will not cause chemical reactions on the filter. These filters also feature low air resistance, and a low moisture pickup which eliminates lengthy desiccations.

Ordering Information: Also available in 20.3 x 25.4cm sheets.
