Air Dryer offers alternative to refrigerant technology.

Press Release Summary:



Balston Membrane Air Dryer will dry compressed air to dewpoints as low as -40°F at flow rates up to 100 SCFM. It has no moving parts and operates without attention. Coalescing prefiltration is employed immediately upstream of membranes to protect them from pipe scale, particulate, and liquids. Dryer requires no electrical connections, which makes it ideal for remote and point-of-use installations or for flammable and explosive applications.



Original Press Release:


New Membrane Air Dryer Offers An Economical, Efficient, Reliable Alternative To Pressure Swing Adsorption Or Refrigerant Dryer Technologies!


Tewksbury, MA...New Membrane Air Dryer now available from Parker Hannifin Corporation. will provide pure, dry compressed air and offer an economical, efficient alternative to pressure swing
and refrigerant dryer technologies.

The Balston Membrane Air Dryer will dry compressed air to dewpoints as low as -40°F at flow rates of up to 100 SCFM. As the Balston Membrane Air Dryer has no moving parts, it operates reliably and efficiently without operator attention and maintenance is minimal.

Dry air is achieved by returning a small portion of the dry product air to sweep out moisture, which preferentially passes through the membranes. The degree of drying is controlled by varying the compressed air throughput. The moisture laden sweep gas is vented to the atmosphere, eliminating potential liquid-handling and freezing problems.

Since the Balston Membrane Air Dryer is compact and lightweight, it can be easily mounted in an existing pipeline. Coalescing prefiltration is employed immediately upstream of the membranes to protect them from pipe scale, other particulate, and liquids. The Balston Membrane Air Dryer requires no electrical connections, which makes it ideal for remote and point-of-use installations or for flammable and explosive applications.

Applications for the Balston Membrane Air Dryer include: Low dewpoint instrument air, pneumatic equipment, pressurizing electronic cabinets, analytical instrumentation, prevention of freeze-ups, dry air for hazardous areas, pneumatic autosamplers, general laboratory air supply.
