Many sample systems require zero liquid entrainment, and demand the sample not to be altered. To obtain this goal a membrane filter should be used. A porous PTFE membrane, supported by a sintered stainless steel disk is at the heart of this unit. As a wet sample enters, the membrane only allows gas or vapor molecules to pass through while all liquids are stopped. Our series of membrane filters are uniquely designed to allow the operator quick and easy membrane service while providing high performance filtration. The body contains an integral mounting bracket along with the inlet, outlet, drain, and bypass connections. The threaded cap is user friendly with knurls and flats for optimum infield serviceability. NO connections are broken to service the membrane disc.


The porous membranes are produced from pure PTFE; they are extremely inert and have very low absorption levels. There are two standard grades available for use in low to high flow applications. The -1 (0.1 micron) is a low flow type membrane suitable for most liquids and the -2 (0.8 micron) is a high flow type recommended for higher surface tension liquids.
