GUARDIAN MEMBRANE SEPARATORS

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 disc 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 M1 (0.1 micron) is a low flow type membrane suitable for most liquids and the M2 (0.8 micron) is a high flow type recommended for higher surface tension liquids.

(*) Preliminary Data

Guardian Membranes are also offered with integral coalescing pre-filters. A 50C grade element is mounted before the membrane to remove most liquids and solids, thus providing longer membrane life. This integral package minimizes dead volume, panel space, and leak points. The combo units accept the same membrane kits as our standard Guardian units. Part numbers are specified at the bottom of the attached chart.

The SML.205.221.M3 is designed to remove water from liquid hydrocarbon streams. The membrane is constructed with a special support layer to increase pressure drop. Hydrocarbon liquids pass through the M3 microscopic passages while water and other high surface tension liquids are blocked.

Fine immiscible liquid droplets are removed from the stream while allowing the unaltered hydrocarbon liquid to pass.
