Atlas Copco 13 HP CR Gas-Powered Cast-Iron Piston Air Compressor

Atlas Copco CR 13 HP gas drive: 24.6 CFM at 100 PSI with no electrical service

This is the compressor for work that happens where there is no power: roofing and framing crews, fence and deck builders, mobile tire and fleet service, farm and ranch repair, pipeline and utility trucks, and rental fleets. A 13 HP Honda or Kohler engine drives a cast iron, splash lubricated two stage pump on a 30 gallon horizontal ASME tank, delivering about 24.6 CFM at 100 PSI and 23.6 CFM at 175 PSI. That is the output of a 5 to 7.5 HP electric two stage, enough for two framing nailers and a 1/2 inch impact at the same time, a 3/4 inch impact on truck lugs, or a sandblaster with a small nozzle.

Honda or Kohler. Both are 13 HP four stroke engines with recoil start plus an electric starter; the Honda carries a small premium, the Kohler is the lower price. Either way, bring a battery for the electric start and plan on gasoline, an oil change schedule for engine and pump, and a spot on the truck where the exhaust clears the cab. The unit weighs about 485 pounds dry and measures roughly 42 by 24 by 44 inches, so it needs a flatbed, a service body or a trailer, and a forklift or a lift gate to load it. Bolt it down with isolation pads.

Running notes. The pump is rated for 100 percent duty, so it can run continuously as long as the engine has fuel. Keep the intake filter clean on dusty sites, drain the tank daily, and use a filter regulator at the tool end. Noise at the compressor is about 92 dBA, so hearing protection is needed nearby.
