Membrane Filter Housing - Model GMS170

The Headline Guardian Membrane Separator filter consists of a highly porous PTFE membrane in a stainless steel or PTFE housing with two bypass ports, inlet and outlet ports.

This GMS170 filter has an integrated grade 50CS coalescing pre-filter fitted before the membrane. This intelligent design removes most solids & liquids before they reach the membrane, this helps to maximize the life span of the membrane. 

Not only that, it has a small internal volume for fast sample results and is mounted vertically (bowl up) or on it's side. This allows pipework to stay connected whilst servicing the internal components. 

Each assembly is supplied with a Hydrophobic/Oleophobic Membrane bonded to a Viton O-ring.

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 M1H (0.1 micron) is a low flow type membrane suitable for most liquids and the M2H (0.8 micron) is a high flow type recommended for higher surface tension liquids.

More about Guardian Membrane Separator Housings:

Many sample systems require zero liquid entrainment, and demand the sample not to be altered. At the heart of our Guardian Membrane Series is a porous PTFE Hydrophobic/Oleophobic membrane which is supported by a stainless steel disc.  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.  Our GMS105 products also features an “Atomizer Plate” which spins the gas flow dropping much of the liquid mass out before contact is even made with the membrane.  This rotation assists in keeping the membrane particle free too.  We have further reduced the internal volume to minimize the sample lag time.
