Compressed Air Dryers

Find the Right Air Dryer for Your Compressor

A compressed air dryer removes water vapor from compressed air before it reaches your tools, controls, and production equipment. Compressed air holds moisture the moment it leaves the compressor, and as that air cools inside piping, tanks, and hoses, the vapor condenses into liquid water. Left untreated, this condensate corrodes valves and fittings, washes out lubrication, and creates blockages that slow production down. 

An air dryer for your compressor addresses this problem before it starts, pulling moisture out of the airstream so only dry air reaches your system. Pressure dew point requirements, ambient temperature, air quality standards, and available floor space all point toward a different drying technology for your application.

KAESER builds four types of compressed air dryers to match different operating conditions.
