Rothenberger Roairvac 1.5 CFM Refrigerant Vacuum Pump

Rothenberger Roairvac Two-stage rotary vane pump for evacuation in accordance with DIN 8975. The Double Stage of these pumps make it feasible to achieve the final vacuum level requested for these type of systems. Besides, the solenoid non-return valve avoids any oil mixture due to the backflow after a power interruption or any other process interruption.Vacuum pump for air evacuation of closed systems (air conditioners, tanks, etc). This equipment is specially designed for Air Conditioning and Refrigeration systems.

Key Features:

• Vacuum gauge with integrated drag indicator enables simple and quick control of the evacuation process
• Thermal cut off switch protects the unit from the motor overheating
• Standard 1/4" SAE connection, as well as 5/16" SAE and 3/8" SAE adaptor included in delivery
• Special filter reduces oil mist and exhaust vent
• Solenoid check valve to protect the refrigeration system from oil contamination during power outage
• Removable cable prevents cable damage
