ADG introduces their new Rail Exhaust Extraction System. This system offers multi-bay service and ease of use with auto hose retraction. It utilizes high quality aluminum extruded rail coupled with trolley mounted fan assisted hose retraction holsters. Closing the drop end dampeners simplifies hose retraction. The system offers optional radio controlled fan motor switches at the drops, allowing technicians to shut the blower motor down from their bays when not in use.
