GDHM Series desiccant Air Dryer

GDHM Series Desiccant Air Dryer

Dual Tower Setup

The GDHM Series desiccant air dryers use the proven “Pressure Swing Adsorption” (PSA) method for drying wet compressed air. The unique design of this unit allows for the dryer to start and stop with a compressor or point-of use equipment to eliminate purge loss when off. The solid state memory feature allows the dryer to start where it left off – preventing wet air downstream.
