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.
