Rotary Screw Models Performance Features

  • Continuous airflow eliminates need for air storage tank.
  • Cost-effective – more air volume (CFM) for your dollar.
  • Instant power upon arrival.
  • More air volume (CFM) per square foot of mounting area.
  • On-board air allows hitch to be available for towing equipment.

Reciprocating Model -

Thermal Characteristics

  • Heat rejected to hydraulic oil by compressor motor and vehicle pump, assuming the pump has the same efficiency as the compressor motor and assuming full load operation at 175 psig compressor discharge:
Heat rejection to hydraulic oil – BTU/hr
Oil temperature degrees above ambient
59 F
  • Heat rejection capability of compressor oil cooler when used as auxiliary cooler for other vehicle-mounted hydraulic equipment, assuming a maximum oil temperature of 75 degrees Fahrenheit above ambient temperature (with compressor not running other than cooling fan):
Heat rejection to hydraulic oil – BTU/hr

Compressor Pump Type

  • Cast iron design with splash lubrication
  • Travel limiters on inlet and discharge valves
  • Two-stage four-cylinder reciprocating pump with belt drive

Compressor Drive

  • Conservatively designed, extended life, dual “B” section belt drive system
  • Convenient belt tension adjuster bolt for future belt tensioning if needed
  • Cast iron gear-type motor with case drain features; hydraulic manifold has integral pressure bypass, solenoid bypass valve (for unit on/off control) anti-cavitation, adjustable flow control, cooler relief (oil bypasses cooler in colder climates); closed-circuit version has a load sense port to signal variable displacement pump
  • Built-in 3000 PSI hydraulic relief valve


  • 14″, 12V DC electric, straight blade, high-efficiency cooling fan
  • Built-in hydraulic oil cooler
  • Cooling air enters through fan, exits through cooler


  • Compressor oil level sight gauge
  • Discharge pressure gauge
  • Hour meter (records pump run time only – fan can run without adding hours)
  • Air Cleaner

    • Heavy-duty single stage with replaceable element

    Service Outlet

    • One 1/2″ FNPT connection and -4 air pressure sense port for connection to receiver

    Hydraulic Connections

    • -8 inlet and -12 outlet, -4 case drain, -4 pressure sense (on closed-center hydraulic models)


    • 12-volt DC output signal for speed control idle-back feature
    • Conveniently located service panels for all routine materials
    • Discharge temperature shutdown switch
    • Easy access drain for compressor oil
    • High quality e-coat primer and powdercoat finish inside and out
    • Internal vibration isolation of compressor pump and drive system
    • Lifting provisions at four corners of frame base
