  • •  Available ISO Ratings: ISO 7, ISO 8
  • Choose between two models to meet your outlet flow requirements
  • Membrane module consists of bundles of hollow fiber, semipermeable membranes, each with a perfectly circular cross-section and uniform core, contributing to strength
  • Includes gas pressure regulator, control valve and instruments, a coalescing filter and carbon filter (to remove oil vapors and particles from the feed line, and moisture membrane)
  • Feed Air Pressure: 60 – 200 PSIG
  • Feed Air Temperature:  40°F (4°C) to 150°F (66°C) (75°F (24°C) recommended)
  • Power Requirement:   Electricity required only for user-supplier air compressor/conditioner
  • Membrane filter is encases in 304 stainless steel case
  • Stainless steel compression fittings allow connection of incoming and outgoing air
  • Efficient membrane separation design never needs regenerating (unlike desiccant dryers)
  • Gives you control over outlet flow and dew point
  • Membrane-separation technology removes moisture from air stream with no moving parts or power requirements – just a source of compressed air
  • Compressed air enters the center of the fiber bundle at one end of the module under pressure; as it passes through the bundles, water vapor passes through the semipermeable membranes and is discharged
  • Low-maintenance, light-weight, compact design
  • Requires no electrical service—simply connect to a compressed air feed line and it's ready for operation
  • Ideal source for purge gas in moisture-sensitive storage and processing applications
