Product Description

255 m³/h Rotary Vane Vacuum Pump DRV275 for Optical Coating, Freeze Drying.

Characterists

High vacuum performance
Reliable and stable.
High pumping speed to maximise your productivity and performance.
High operating reliability through an integrated high vacuum safety valve.

Advantages

The use of a non-spring rotary vane to achieve low noise, low vibration, and long service life.
A built-in check valve is used to avoid the oil return phenomenon.
Built-in forced-fed oil pump is used to ensure the long-term continuous operation of the pump at atmospheric pressure.
The use of air cooling, oil cooling, water cooling, and other cooling methods ensures a good cooling effect and makes the long-term stable running of the pump as well as the stable pumping performance.
A reasonable structure has the advantages of easy assembly and disassembly, as well as the fast and easy maintenance.
