We are a leading worldwide supplier of high efficiency filters for a variety of industries and applications.
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. Our Model GMS170 takes the built-in coalescing filter one step further by inverting the complete assembly and making it easy to service by eliminating the need to break port connections. Here too we reduced internal volume for better conditioning results.

The GMS120/122 series utilizes the traditional T-type design, with a coalescing pre-filter built into the assembly. The GMS127G utilizes a pyrex bowl for at a glance monitoring. The membrane is mounted on top with a vertical exit point, which assists in keeping it clean. This series utilizes a unique membrane holder plate which simply slides out from underneath the collar once it is loosen and lifted. This plate allows membrane maintenance without breaking any connections.
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.
Our Oleophobic membranes designated by the “H” suffix (i.e. MT.33.M2H) have an extra thin layer which repels hydrocarbons and will block both water and hydrocarbons. They exhibit the same flow rate characteristics as our standard membranes.

The above flow rates are with a 3 PSID across the membrane and are for reference purposes only. The flow may be increased, but we do not recommend exceeding a 5 PSID in order to maintain the integrity of the membrane. The M1 membrane is suitable for separation of most liquids from gases. The M2 membrane is best suited for the separation of water and other high surface tension liquids from gases.
