The Stellar® 30R Hydraulic-Driven Rotary Screw Air Compressor is robust yet compact and lightweight. The precision-engineered, rugged air-end is designed for 100% continuous-duty operation. As a result, the 30R will provide plenty of air for most mechanic truck applications, and its compact size and minimal weight make it a great fit for smaller service trucks as well.


Additional Information

Durability Standard

  • Rotary screw compressor air-end is oil injected to eliminate metal-to-metal contact of the two compressor screw lobes. The result is an air compressor designed for 100% continuous-duty cycle with extremely long life.
  • Rotary screw compressor air-end is belt-driven by a heavy-duty hydraulic motor for reliable service.
  • Oil/water separation system and oil filtration of the compressor for long life.
  • System includes a dual-purpose, integral cooler for both the compressor oil and the truck’s hydraulic oil. For most applications, this eliminates the need for a separate hydraulic oil cooler, saving you money.
  • For safety and reliability, the system includes a pressure-relief valve, minimum pressure/check valve, automatic air pressure relief upon shutdown and a safety relief.

Ease of Use

  • Bulkhead fittings for quick and simplified hookup. Hydraulic supply lines, return lines and electric power supply connector are all located at one end of the compressor enclosure.
  • Oil level check/refilling is simplified by access from outside the unit.
  • Includes an attractive powder-coated aluminum enclosure with easy-to-read temperature gauge and hour meter. A resettable safety relay is also conveniently located on the outside of the enclosure.
  • Automotive-type air cleaner for high capacity and long life.
