  • OL-3 - 1-3 Users
  • OL-7 - 4-7 Users
  • OL-10- 8-10 Users
  • Oil-less piston compressor heads
  • Integral desiccant drying system
  • In-line filter to ensure delivery of clean, dry air 
  • Air is stored in an ASME-certified tank
  • Equiped with a low voltage relay
  • Enable operation from a remote location
  • Free of water, oil and other contaminants
  • Excessive circuit lengths should be avoided to reduce voltage drop during compressor operation. Voltage measurements should be taken while the compressor is running. A static voltage reading is not a true indication of voltage supply during operation.
  • To avoid compressor overheating and thermal shutdowns, the installation site must be properly ventilated and, if necessary, air conditioned to prevent ambient temperatures from exceeding 104°F/40°C.
  • Compressors installed outdoors must be protected from rain, snow, direct sunlight and excess dust. Temperature limits and ventilation recommendations must also be followed.
  • Compressor motors are controlled by a pressure switch and will have line voltage applied to them whenever the tank pressure is below 80 PSI. The compressor may start without warning.
