KMMs keep moisture from ruining paint jobs, clogging sandblasters, and fouling pneumatic instruments, valves, and controls. Operation Compressed air, saturated with water vapor, flows through a bundle of parallel, tube-shaped membranes. As the compressed air passes along the length of the bundle, water vapor passes through the membrane, dehydrating the compressed air. The separated water vapor is then purged from the membrane bundle housing with a stream of the dried air and exits to atmosphere through a port in the bottom of the housing. Automatic Purge Saver control The Kaeser automatic Purge Saver (PS) valve prevents the unnecessary loss of valuable compressed air. The PS valve is strategically located to automatically stop the flow of purge air while maintaining pressure on the membrane tubes and keeping the bundle housing at atmospheric pressure. This design not only saves energy and purge air, it also extends the life of the membrane bundle by preventing the excessive flexing of the membrane material that results from pressurizing and depressurizing the dryer. The Purge Saver valve can be actuated by an external signal, such as the air compressor unload signal or from a device no longer demanding air. Easy installation With the new modular design of the KMM, installation is easy. The KMM is lightweight, so no support is needed Continued on back
