Walmec North America’s WNA AMD-035 membrane dryer uses four-stage filtration to provide ultra-clean and ultra-dry air in compressed air applications. It has a flow rating of 35 scfm and maximum working pressure 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 0.01 microns and 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 damage from vibrations and enables the dryer itself to be installed in virtually any position.
Differential pressure gauges indicate when maintenance is required, and any maintenance can be easily done by installing the appropriate service kits without the need to remove the dryer from the compressed air system.
