Walmec Offers Four-Stage Membrane Dryer

Walmec North America (Mazeppa, Minnesota) says its WNA AMD-035 Membrane Dryer is ideal for applications where compressed air application requires ultra-clean, ultra-dry air.

According to the company, the WNA AMD-035 Membrane Dryer has a four-stage pre-filtration that is critical to its longevity and function. It reportedly has a flow rating of 35 SCFM (standard cubic feet per minute) 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 reportedly 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 enables the Membrane Dryer 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. The company says there is no need to remove the unit from the compressed air system.

The AMD-035 Membrane Dryer is said to be ideal for applications such as waterborne paints or other sensitive tasks that require the highest standard of clean and dry compressed air. Walmec says it is easy to install, use and maintain.
