C SeriesCool Force™ Cycling, Refrigerated Air Dryer

Pure-Aire’s Cool Force™ Cycling, Refrigerated Air Dryer raises the bar for reliability and lowest total cost of ownership. The

“C” Series maximizes your operation’s uptime and productivity. It is designed to outperform any refrigerated dryer available.

Cool Force™ technology ensures a consistent dew point is held under 40˚F. The Pure-Aire line of compressed air products is

engineered, manufactured and supported in the United States.

Our Components Make The

DifferencePremium components are utilized to ensure

unmatched reliability and performance.

Pure-Aire is the ONLY manufacturer to offer

BOTH heat exchangers and the circulation

pump in stainless steel metallurgy.

Best-In-Class Warranty5 Year Non-Prorated Warranty

on Both Stainless Steel Heat

Exchangers – Including Parts

AND Labor.

One Year Coverage on All

Components Including Zero-Loss

Drain

Cool Force™ CyclingForced circulation of coolant through a

stainless steel heat exchanger eliminates

dew point fl uctuations seen in competitive

dryers where the heat exchanger is

immersed in the coolant. The refrigeration

compressor cycles to match air demand.

Dual setpoints safely ensure maximum

cooling throughout the entire fl ow of

operation.
