HEV Venturi and Oilmaster™ Team Up to Eliminate Oily Graphite Particulate at Major Forging Facility
|
From Met-Pro Corporation
NTN Driveshaft Inc. of Columbus, Indiana had a history of high maintenance costs with existing dry filters to control oil, dirt, smoke, and other particulates generated by the operation of their 2,000 ton presses. The NTN filter press process creates an oily translucent vapor containing a graphite particulate which exits the press at a rate of 12,000 ACFM at a temperature of 120°F. Since Duall Division had successfully designed and installed a phosphate plating line ventilation system at NTN in 1993, they contacted Duall Division again to supply an oil mist collector that would meet their air emission requirements and reduce their substantial maintenance expense.
