Membrane Air Dryers (-40/C Dewpoint)

Parker Balston Membrane Air DryerBalston Membrane Air Dryers offer superior coalescing filtration technology with an innovative membrane system to deliver clean, dry compressed air to dewpoints as low as -40°F (-40°C) and provide low cost operation with minimal maintenance. These dryers are engineered for easy installation, operation, and long term reliability.

How the Technology Works:

Water vapor from the compressed air supply passes through the hollow fibers of the membrane. At the same time, a small portion of the dry air product is redirected along the length of the fibers to sweep out the water vapor laden air which has permeated the membrane. The moisture-laden sweep gas is then vented to the atmosphere, and clean, dry air is supplied to the application. The drying power of the membrane is controlled by varying the compressed air flow rate and pressure. The Balston Membrane Air Dryer is designed to operate continuously, 24 hours per day, 7 days per week. The only maintenance required is changing the prefilter cartridge twice a year. This semi-annual maintenance takes approximately 5 minutes.

Features and Benefits:

  • Offer a reliable, efficient, and economical alternative to pressure swing and refrigerant dryer technologies
  • Require no electricity thus lowering operating costs
  • Dewpoints as low as -40°F (-40°C)
  • prevent freeze-ups
  • Explosion proof
  • Silent operation
  • No desiccant to change
