Hot parts washers generate steam and water vapor that can cause deterioration of the surrounding equipment. With a Quickdraft Venturi exhaust system, operators can enjoy a steam free work zone. The system removes steam from the parts washer cabinet during the cleaning cycle and at the end of the cycle prior to opening the door, preventing damaging discharge into the plant. The Venturi system automatically compensates as atmospheric pressure changes in the building to maintain a constant negative pressure inside the cabinet. Made of stainless steel with NO moving parts in the exhaust flow, the corrosion and blower bearing failure common in systems with in-line blowers is eliminated.
