INDIANAPOLIS. Miller Electric Mfg. Co. introduced its EnPak Air Power 40 truck-integrated, engine-driven air compressor and generator here at the NTEA Work Truck Show. The company said the new unit eliminates the need for hydraulically driven stand-alone or under-hood compressors and integrates seamlessly into a truck’s electrical and fuel systems.
According to Miller, along with doing away with hydraulic compressors, the key advantage of the EnPak Air Power 40 is it “reduces fuel use and engine hours by allowing service personnel to run tools with the truck turned off.”
That feature will lower fuel costs up to 30%, reduce truck engine hours [expended] up to 60%, lower truck noise and reduce exhaust fumes in the work area, Miller stated.
The company pointed out that the EnPak Air Power 40 is designed for service truck operators who regularly use compressed air and generator power but don’t need the hydraulic functions first introduced in its EnPak Mechanics Series. “This makes it more accessible for service trucks that aren’t equipped with hydraulic cranes but still require the use of heavy-duty air and power tools, such as impact wrenches, jacks, grinders and welding and cutting equipment,” Miller stated.
Prior to EnPak, field service technicians relied on either a hydraulically driven standalone or under-hood compressor, said Miller. This required leaving the truck running throughout the day, which added unnecessary drivetrain hours to service trucks. EnPak Air Power 40 now runs the air compressor and generator with its 27-hp. Kubota diesel engine, which ties directly into the truck’s fuel and electrical systems. Field service technicians now only fill up the truck’s diesel tank and can run all critical tools with the truck turned off.
EnPak Air Power 40 features Miller’s Air Pak 40 variable-speed rotary screw air compressor that is rated at 40 cfm at 100 psi, with 175 psi maximum pressure. This allows service technicians to use air tools without having to stop and wait for pressure to build. It also features 6,000 watts of generator power for welders and power tools, plus an optional 2,400 watts of pure sine wave EnVerter power for accessories such as lights and laptops.
Miller also stated the unit is up to 10 dB quieter when compared to running the same tools off the truck’s engine, and the work environment is substantially improved as truck exhaust isn’t filtering into the work area. EnPak Air Power 40 also features a vertical exhaust to filter fumes up and away from the work area.
