The Rothenberger ROAIRVAC R32 is used to evacuate all refrigeration circuits according to DIN 8975. A vacuum of less than 25 microns is achieved by the two-stage rotary vane pump, making it ideal for all refrigeration system builders and technicians. It features a 4-pole motor for increased torque and long service life, and is also suitable for highly flammable refrigerants such as R32. The solenoid check valve protects the refrigeration circuit from oil contamination in the event of a power interruption. The lightweight, high-quality housing protects internal components, while the gas ballast valve reduces water vapor in the oil reservoir. A special filter reduces oil mist at the discharge connection, and the easy-to-read oil level is indicated through a sight glass. The unit has an easily accessible oil drain plug for quick draining, and a thermal switch protects it from overheating. It includes a standard 1/4" SAE connection, as well as 5/16" SAE and 3/8" SAE adapters. The delivery also includes a detachable cable to prevent cable damage. Further technical features include a tank volume of 0.33 liters and a volume flow of 85 liters per minute.
