Roots air Ejector Water Ring pump system adds the Air Ejector before Water Ring Pump of Roots Drinking water Ring pump program.Comparing to Roots Drinking water Ring Pump system which has the same amounts of Roots pumps，there are the following features；
Large vacuum，high Air Vacuum Pump china displacement in smaller inlet gas pressure
Motor isn’t reqired for Air Ejector，so that zero power consumption；Energy saving
With Air Ejector，the gas pressure difference between input and output has been reduced，which will reduce the comoressing heat and make the operating more reliable for Roots pump.
APPLICATIONS：
Suitble for high vacuum distillng，vacuum vaporizing and vacuum dehydrating-crystalllzation in chemical substance and medicine sector；vacuum drying and vacuum impregnation in electrical and light textile industry；frozen-dryer in food and medicine market etc.
Roots Pump with Air flow Ejector and Water Band Pump Vacuum System
Control and communication are the essential factors for increasing program availability. The intelligent interface technology of the Ever-power allows very great adaptation and monitoring of the procedures. By integrating condition monitoring, details about the health of the vacuum system is always available. In addition, condition monitoring increases system availability, allowing users to plan maintenance and repair steps in a good and anticipatory method and prevents cost-intensive creation downtimes. These advantages result in a long service life and maximum operational safety. ever-power vacuum pumps can either end up being aligned vertically or horizontally. This enables maximum pumping acceleration and a far more customized and effective utilization of space at the customer’s production site.
The maintenance and energy costs of the HiLobe are a lot more than 50% lower compared to conventional Roots pumps. This is due to a get with energy efficiency class IE4 and the particular rotor geometries of the pumps. The pumps are hermetically sealed to the atmosphere and also have a maximum essential leakage price 
of 1·10-6 Pa m3/s. Dynamic seals are eliminated and, as a result, maintenance is only required every four years. An innovative sealing concept in the suction chamber makes the usage of sealing gas superfluous generally in most applications, which also offers a positive influence on the working costs. Since the operation of the Ever-power Roots pumps is possible even at ambient temperatures as high as over 40°C with flexible atmosphere cooling, cost-intensive drinking water cooling is unnecessary.
