Miniature, regenerative compressed air dryers capable of achieving dew points of better than -100°F (-73°C) and for flows to 3 scfm (85 slpm). Ideal for OEM and point-of-use applications requiring ultra-dry air, small size, and economical pricing. Fits easily into a shoe box! Accessories include inlet and outlet filtration, flow and pressure regulation, and a NEMA-4 enclosure.

Product Features:

Ultra-dry air to –40°F pressure dewpoint (–100°F ADP also available)
Flow capacities to 3 scfm (85 lpm) at operating pressures of 3,5 - 10 bar (50-125 psig)
Extremely compact, lightweight anodized aluminum construction
Easy to install and no regular maintenance required
Regenerative operation eliminates ongoing expense of desiccant replacement
Non-corroding purge muffler comes standard for quiet operation
Governed by solid-state timer for prec ise control and lower power consumption
Sizes to match the output air flow of fractional horsepower compressors
Manufactured in a Demand Flow Technology environment to ensure world-class qual ity and on-time delivery

Principle of Operation:

The dryer employs Pressure Swing Adsorption (PSA) technology to remove water vapor from ordinary compressed air. The 4-way valve directs the wet air into one of the two desiccant chambers, where nearly all of the water vapor is removed. The ultra-dry air leaving the desiccant chamber passes through the outlet shuttle valve to the application. A precision orifice in the outlet shuttle valve disk allows a portion of the dry air to be redirected back through the off-line desiccant chamber, purging it of the accumulated moisture. The purge air then exits the unit through the 4-way valve and muffler. A solid-state timer governs the process by controlling the 4-way valve.
