Donaldson Air Dryers

Air dryers remove water vapour from compressed air, rather than the liquid water a separator or drain deals with. Air leaving a compressor is warm and saturated, so it drops out more water as it cools in the pipework downstream - which is where corrosion, frozen lines and damaged pneumatic components come from.

Dryers are selected on flow rate, working pressure and the pressure dew point required for the application. Search by Donaldson part number, or tell us the compressor output and what the air is being used for.
