Compressor Runs Safely in Underground Mining Applications


British Columbia-based VMAC said its Raptair diesel-driven, stand-alone air compressor is now available in a U.S. Mining Safety and Health Administration approved version. The primary modification to enable approval was a change to the engine; the MSHA-approved version uses a Kubota engine that runs at a slower speed than the diesel offered in the Raptair60. The approved engine enables the compressor to provide more than 52 cfm and lower RPM also make the system quieter than the 60-cfm version. Although there is a decrease in cfm, the company claims the MSHA-approved Raptair50 is a high-performance unit that can be truck- or skid-mounted, and provides enough power to run most common air tools used in mining operations.
