Membrane Dryer
Compressed Air Dryer
Air Dryer
GSA PMD series membrane dryer type

Membrane dryer refers to a dehumidication membrane that removes water vapor from
compressed air. It is used in pneumatic components, air bearings, air spindles,
medical equipment, air guns and pneumatic brakes for vehicles & trains.

Compressed air runs through the core
pipe, and is then diverted to the membrane element in the housing. The
compressed air, which is still tumid, flows through the highly selective hollow
fiber membranes of the membrane element inside. The purge air, which is
required for drying, diverges continuously at the outlet area of the membrane
element, and expands to atmosphere using a fixed nozzle orifice. Due to this
expansion, the purge air becomes very, very dry as the water vapor now fills an
expanded volume. The dry purge air flows over and around the exterior of the
membrane fibers. As a result, air flows in one direction outside the membrane,
separately only by the membrane wall. Humid compressed air flows inside the
membrane as dry purge air passes outside. Due to the difference in moisture
content in the passing airstreams, moisture from the compressed air is drawn
into the purge air. Twist 60 technology ensures maximum drying efficiency.
Dried compressed air leaving the membrane element. Saturated purge air is
released back to atmosphere.

Features & Benefits

• Flow range of 135~600 liters/min.

• Higher volume flows are achieved by the parallel connection of several
  membrane dryers

• Filtration and drying in a single unit

• Filtration immediately before the membrane

• Fast element replacement, low maintenance

• Integral surge diverter

• Highest possible performance

• Maximum reliability even in the toughest environments

• Achieves dew point in 5 minutes or less

• No energy consumption

• No moving parts thus reliable even in mobile applications
