WALTER VT 220 refrigeration dryer

The WALTER VT 220 refrigeration dryer was manufactured in 2013 by the Polish company WALTER Kompressortechnik. The device is used to eliminate water and steam from compressed air, which can damage equipment or tools powered by compressed air. The dryer lowers the temperature of the compressed air and then removes water and oil particles from the air flowing through it.

The WALTER VT 220 allows an air flow of 3.6 m3/min with a maximum inlet pressure of 16 bar. The condensation process (water condensation) starts at a pressure dew point of 3°C. The machine can be used at an ambient temperature of +4 to +43°C. The total weight of the machine is 70 kg.
