Features and Benefits

Ambient Air Filtration – This washable and replaceable filter keeps your air compressor cleaner and cooler. Conveniently accessed from the front of the unit, this feature reduces maintenance and keeps your unit running at the ideal temperature.

Oversized Air/Oil Cooler – Easy-to-access and oversized to allow for higher ambient operating temperatures

Spin-on Filtration – Spin-on air/oil separators and oil filtration allow for quick and effortless replacement

Condensate Trap – The standard condensate trap, located at the discharge of the air cooler removes bulk water. Includes electric solenoid drain valve.

Low RPM Air End Assembly – The oversized air end assembly allows for a low RPM design which provides reduced maintenance,cooler running conditions, and an extended life expectancy.

Direct Drive Design – Direct drive eliminates gear-sets which increases efficiency, reduces noise and vibration levels.

Integrated Oil Sump Tank – The oil sump tank is integrated directly with the air end, filtration, thermal valve, and MPCV. This compact design reduces hose connections and lessens the chance for oil leakage.

TEFC motor (totally enclosed fan-cooled) – All RK-VSD units come standard with a TEFC motor. This feature protects the motor against dirty environments which increases bearing life and the overall longevity of the compressor.

VSD Inverter – The inverter allows for unlimited motor starts per hour, consistent discharge pressure, soft motor starts, up to 85% turndown, and reduced power consumption. Unlike a fixed speed machine, KW consumption stays on par with your compressed air demand, resulting in significant energy savings.
