Compressor Features

  • Compressor: Oil flooded rotary screw, continuous duty, industrial air compressor. Direct coupled to motor for positive alignment.
  • Electric Motor: 230/460/575 volt Nema T-frame, C-face, double shaft, open drip proof squirrel cage induction type.
  • Motor Starter: 460 volt, full voltage magnetic starter with 120 volt controls, Nema 1 enclosure, circuit breaker transformer and three-phase overload protector.
  • Coupling Drive: Compressor is flange mounted to motor C-face for positive alignment and direct driven by zero maintenance coupling.
  • HD Air Intake Filter: Oversized dry type, single stage with replaceable element
  • Inlet Modulation Control
  • Cooling System: Air cooled with air cooled aftercooler and factory filled with Palasyn 45 synthetic lubricoolant. Equipped with a microfiber full flow oil filter.
  • Controls: Full modulation, solenoid controlled for smooth control and lowest possible no load power. Automatic start/stop or constant spped timed dual control.
  • Instrumentation: Air pressure gauge, hour meter, discharger temperature and overpressure shutdown.
  • Protective Devices: Class 20 overload relay, high temperature and overpressure shutdown.
  • Mounting: Base mounted, no special foundation required. Optional tank or platform mounting available.
  • General: Consult factory for options or accessories not listed. Specifications subject to change without notice.
  • Deluxe Gauge Panel: Deluxe gauge panel includes 2.5" liquid filled sump and line pressure gauges, 2.5" oil temperature gauge, with oil filter and separator differential pressure gauges.
  • Air Cooled Aftercooler: Double pass air-cooled aftercooler with thermostatic control for maintaining the appropriate oil operating temperature and reducing the discharge air temperature to within 15 degrees of ambient.
  • Auto/Dual Control: Compressor control that allows the unit to be operated in continuous run mode or with an automatic timed shut down. Auto control allows multiple machines to be operated in a lead-lag condition.
