Miniature Heatless Dryers 0.1 To 12 SCFM

PUREGAS Regenerative Desiccant Air Dryers

PUREGAS manufacturers heatless regenerative miniature air dryers using pressure swing adsorption (PSA) technology. These mini air dryers are designed to provide trouble free dry air to maximize the effectiveness your air system. If it is for your point of use or an original equipment manufacturer, we can supply units for -40°F or -100°F dewpoint outputs.

Some Typical Dry Compressed Air Applications:

MDH-Series Miniature Desiccant Air Dryers capacity from 0.1 to 3.2 SCFM

The MDH mini air dryers can be used with fractional horsepower compressors. The MDH heatless air dryer can produce reliable, low dewpoints, and only take up a small amount of space. With its small footprint, it can be placed inside equipment cabinets for original equipment manufacturers (OEM’s) or at a point of use in your production facilities.
