ROAIRVAC R32 9.0 – Two-stage vacuum pump


Single Page Thumbnail

A two-stage vacuum pump (ROAIRVAC series) is a reliable, high-performance device designed for evacuating all refrigeration circuits in accordance with DIN 8975. Ideal for air-conditioning systems, refrigeration systems, and heat pumps, its two-stage rotary vane pump efficiently frees systems of residual moisture and achieves a vacuum of less than 25 micron.

Two-stage vacuum pumps in the ROAIRVAC R32 series feature an integrated solenoid check valve to protect the refrigeration system from oil contamination during power outages. Equipped with a gas ballast valve, thermal switch protection, and a special filter to reduce oil mist on the exhaust vent, it ensures high evacuation power, safety, and extended service life.

Key Features & Application Benefits

  • Solenoid check valve: Protects the refrigeration system from oil contamination during power outage
  • Vacuum gauge with drag indicator: Enables simple and quick control of the evacuation process
  • Light and high-quality casing: Protects the integrated components
  • Gas ballast valve: Reduction of water vapour in the oil container, guarantees higher evacuation power and extended service life
  • Special filter: Reduces oil mist on exhaust vent
  • Gauge-glass & oil drains: Enables simple oil-stand monitoring and easy emptying
  • Fast oil filling: Quick filling of oil without spilling (no special funnel necessary)
  • Thermal switch: Protects the unit from motor overheating
  • Standard 1/4″ SAE connection: Includes adaptors for 5/16″ SAE and 3/8″ SAE
  • Removable cable: Prevents cable damage
  • Four-pole motor: Increased torque and long service life (ROAIRVAC R32 1.5, 3.0, and 6.0)
  • Practical operating instructions: Always within view on the unit
