空气喷射真空泵使用大气作为动力介质。凭借可生成 50 到 100 毫巴中等真空的液环真空泵,空气喷射真空泵可以达到 5 毫巴的吸入压力,具体取决于设计和操作条件。
只要是低能耗问题,就最好将带有冷凝器的蒸汽喷射泵连接到液环真空泵的吸入端,从而喷射泵的动力介质(蒸汽)会被冷凝且不会像空气喷射泵一样负载液环真空泵。
Together with Mona Neubaur, Minister of Economic Affairs of the German state of North Rhine-Westphalia, GEA CEO Stefan Klebert has opened a new technology center for pharmaceutical freeze-drying systems in Elsdorf, Germany. GEA employs approximately 260 people at the facility, which combines research and development with production and service under one roof.
