20 - 350 CFM 20 - 350 CFM High Inlet Air TemperatureDryer System High Inlet Air TemperatureDryer System

Power ON Light The Rally 4 Dryer System features our advanced 4 in 1 drying system. Incorporated within each GHTdryer is an aftercooler, 5 micron filter/separator, pre-cooler/re-heater and evaporator. The need for additional drying equipment has been eliminated. GHTdryers are perfectly suited for placement after a reciprocating type air compressor where clean, dry compressed air is required.
