Nett’s S-Series Filters Listed By MSHA For Coal Mines

Posted on June 27, 2007

Nett Technologies Inc.’s SN and SO-Series diesel particulate filters have been listed by the Mine Safety and Health Administration (MSHA) for installation in coal mine applications, the company announced. The listing is an expansion of currently listed S-Series filters for use in metal non-metal mines. SN and SO-Series filters contain an NO2 suppressant which allow these specially-catalyzed filters to be used in coal mines, and are one of only a few passive technologies listed, Nett said.

The SN and SO-Series filters have been tested by MSHA laboratory testing facility and listed for installation on diesel-powered mining equipment, reducing diesel particulate emissions by 85% and 87% respectively. SN-Series filters utilize a Cordierite (ceramic) filter monolith to trap diesel particulate emissions. SO-Series filters, on the other hand, use Silicon Carbide monoliths for enhanced high-temperature durability. Both series are available in a range of sizes to fit applications from 20 to over 700 hp.
