Castair R10112VG11 — 10 HP Single-Phase Rotary Screw Air Compressor — 120-Gallon Vertical
The Castair R10112VG11 is a 10 horsepower, single-phase rotary screw air compressor with a 120-gallon vertical tank. It delivers 40 CFM at 100 PSI with a 100% duty cycle — meaning it can run continuously without overheating or needing cool-down periods. If your shop needs constant air supply and you are on single-phase power, this is your machine.
Why Rotary Screw?
A rotary screw compressor runs continuously and delivers constant air pressure without the pulsation and cycling of a piston compressor. There is no start-stop cycling, no pressure drops between tank refills, and no recovery time. When your shop has multiple technicians running air tools simultaneously, a rotary screw keeps up without the dips in pressure that shut down impact wrenches at the worst possible moment.

Single-Phase Advantage
Most rotary screw compressors require 3-phase power, which many smaller shops and rural locations do not have. The R10112VG11 runs on single-phase power, giving you the benefits of a rotary screw — continuous duty, constant pressure, quiet operation — without the cost of installing 3-phase electrical service.
Shipping and Ordering
- Ships within four weeks of order placement (shipping time, not delivery time)
- All orders receive a courtesy call to confirm conditions and application
Castair has been family owned and operated since 1991. As the name implies — CAST iron, not aluminum. Oil-lubricated pumps running at slow RPMs for quiet operation and extended service life.
