Features and Benefits
The Model EV-SA is a range of air-cooled dry vacuum pumps with a compact design that need no coolant water. Compact design offers greater freedom of installation location, while achieving large exhaust speeds of up to 5,000 L/min. The only utility required is power supply. Low power consumption and quiet operation. Can be used in various environments such as production plants, as well as in testing and research laboratories. Ideal for clean pumping applications, such as for various analyzers and electronic microscopes.
