Blowoff On A Transmission Pan

The Problem

A newly designed transmission pan presented a myriad of cleaning problems for the die-caster. 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 the Application Engineers at EXAIR, 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.


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 tonne 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 jets. When you need to clean, cool, or dry with air, and you’d like to minimise dollars and decibels, EXAIR products can help.
