The Edwards Model 250 Water Cooled Exhaust Trap cools the exhaust gases from the pump and causes particulates to collect in the Exhaust Trap. This prevents the collection of particulates in the exhaust-system. The Exhaust Trap is designed for connection to a pump which is used in an LPCVD nitride process using dichlorosilane or hexachlorodisilane and ammonia. The Exhaust Trap is not suitable for connection to a pump which is used in other processes. The Exhaust Trap is designed to fit BOC Edwards CDP and QDP dry pumps and Drystar MKI, MKII and QMKII dry pumping systems. Your system must incorporate a pressure switch to shut-down the pump if the exhaust system becomes blocked. The Exhaust Trap has a main outer body which is mounted on a baseframe. You can adjust the height of the trap-body in the baseframe to fit the Exhaust Trap to different pumps. The baseframe has castors for ease of movement of the Exhaust Trap and levelling feet so that you can securely locate the Exhaust Trap in its operating position.
