The Walmec North America Membrane Dryer (WNA AMD-035) has a four-stage pre-filtration that is critical to the longevity and function of the membrane dryer. It has a flow rating, of 35 SCFM and maximum working pressures of 150 PSI.
The first- and second-stage filters remove moisture, liquids, dust, rust, scale and other contaminants 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 .01 microns, as well as absorb any remaining moisture or oil vapors.
The Membrane Dryer lowers the humidity level by venting it harmlessly into the surrounding atmosphere. A flexible input hose assembly eliminates the hazards of damage from vibrations in piped compressed air systems and allows the Membrane Dryer itself to be installed in any position.
The four-stage pre-filtration includes differential pressure gauges and comes complete with mounting brackets. The differential pressure gauges provide a visual indication of required maintenance, which is easily done by installing the appropriate service kits. No need to remove the unit from the compressed air system.
