The EVCP-0255 Dry Running Claw compressor

The EVCP-Series compressors are dry contact-less with modular constructions consisting of compartments: pumping and gear chambers are separated by using labyrinth seals. As two claws rotate in opposite direction, the air will be sucked in the pumping chamber, compressed and discharged under pressure. Two gears for synchronizing of claws rotation are placed inside the gear chamber and lubricated with appropriate gear oil. A dust filter on the inlet flange will prevent dust from entering the compression chamber. The compressors are directly driven by a flange motor via a coupling. The claws and compression chamber have a TFE (Teflon) coating to protect the compressor against corrosion from moist in the inlet gasses.

Advantages to the user:

  • High Volume Flow
  • Oil free pumping chamber
  • Corrosion protection by teflon coating
  • Air cooling, no cooling water needed
  • Low energy usage
  • Very little maintenance needed
  • Non contact claw rotation
  • Direct drive
