Because the configuration included channels and blind holes as well as smooth surfaces, a “shaped” air pattern was required for proper cleaning. No single blowoff product would fit the need. An assortment of open copper tubes and drilled pipes was considered, but was rejected as too noisy and expensive to operate. A blower was not an option due to the high purchase price, expensive maintenance costs and frequent downtime. The Solution: With help from our Application Engineers, the company created a cleaning system incorporating a variety of EXAIR blowoff products. (2) Model 6013 High Velocity Air Jets, with their confined airstream, cleared the blind holes, while (2) Model 120022 2" (51mm) Super Air Amplifiers cleaned the channels. A Model 2012 12" (305mm) Standard Air Knife was positioned to blow out the casting’s underside. Comment: There’s no doubt that the casting could have been cleaned just as well by hooking up a bunch of open copper tubes and throwing a ton of air at it. But, at what cost? EXAIR makes a variety of blowoff products because parts come in a variety of shapes and sizes. And, our products operate at a fraction of the air consumption and noise levels associated with open air pipes. When you need to clean, cool, or dry with air, and you’d like to minimize dollars and decibels, EXAIR can help.

After pouring, the castings gradually cool by traveling along a 200 foot long conveyor. At the end, a shake-out conveyor breaks the sand mold so the casting can be removed. Normally, the operator could pick up the part with special gloves and grind the rough edges. However, some castings such as crankshafts, differential housings, and shift parts retained too much heat, making them too hot to handle. The operator had to wait up to ten minutes for them to cool. The Solution: They installed (5) Model 120022 2" (51mm) Super Air Amplifiers over the shake-out conveyor. The high output airflow from each Super Air Amplifier rapidly cooled the parts without shocking them (no cracks or imperfections from cooling too rapidly). When the part reached the end of the conveyor, the operator could proceed immediately. The backlog was completely eliminated. Editor's Comment: This manufacturer had almost given up on finding a cooling solution since the fans and blowers that were tried in the past showed little improvement. Our Super Air Amplifier dramatically reduced the cooling time. As a result, they installed them on their second line. The low cost Super Air Amplifiers are compact, portable and have no moving parts to wear out (which is ideal in a dusty foundry). And, the patented design assures the highest output air volumes possible with the lowest air consumption.
