The vacuum pump for air-conditioning systems with R32 or similar refrigerants works particularly efficiently thanks to the two-stage design, as it minimises the gas backflow effectively. The custom design increases the pumping capacity and enables a vacuum of up to 15 μm. With the186 W power, the model achieves a flow volume of 58 l/h which works extremely fast. The air-conditioning vacuum pump is impressive with its extremely quiet and low-vibration operation - an unbeatable advantage, especially in professional environments such as laboratories.
