Membrane dryer’s four-stage prefiltration produces ultradry air

The WNA AMD-035 membrane dryer from Walmec North America has a four-stage prefiltration to produce ultraclean, ultradry air for compressed-air applications.

The first- and second-stage filters remove moisture, liquids, dust, rust, and scale to 5 microns. An automatic float drain under the second-stage filter opens and expels all collected liquids whenever an ounce or more is present. It is fully automatic with no continuous air loss.

The third and fourth stages remove any remaining particles down to 0.01 micron and absorb any remaining moisture or oil vapors. The membrane dryer lowers the humidity level by venting it into the surrounding atmosphere.

The unit has a flow rating of 35 SCFM and maximum working pressures of 150 PSI.
