Portable Air Compressors

The Rails R70/RX70 Portable Air Compressor is a self-contained, gas engine driven rotary screw air compressor capable of producing 70 cfm at 100 psi* continuously (85 cfm at 90 psi) with plenty of reserve—enough for a wide range of maintenance jobs. It can operate at ambient temperatures from
–20°F to 100°F and can be used in dusty or sandy areas. Every R70/RX70 compressor is operated and tested at the factory before shipment.

-Lightweight, compact, versatile

The R70/RX70 is ideal for section gangs. It is small enough to be moved easily from job-site to job-site but has enough capacity for tamping, driving spikes, running impact wrenches, etc.— jobs that otherwise would require time-consuming hand operations or tie up a large compressor.

-Powerful, reliable engine

The power source is a reliable, fuel-efficient, overhead valve, V-twin cylinder, air cooled gasoline engine.
The R70 features a 25HP Kohler Engine and the RX70 a 20HP Honda Engine.

-Rotary screw compression

The R70/RX70 features positive displacement, oil-flooded, single-stage rotary screw ends. Rotary screw compression provides constant air flow and pressure continuously, regardless of the amount of time it takes to get a job done. There is no need for air storage tanks or waiting for the system to “catch up”. The air ends are warranted for 2 years against defects in materials and workmanship and loss of capacity due to wear.

-Easily transportable

The R70/RX70 weighs under 500 lb. and can be transported on any class of truck or towed on a trailer mount. The compressor’s low profile assures clear visibility for safer, easier transporting.
