DRV275 300m3/H Rotary Vacuum Pump Mechanical Vacuum Pump Optical Coating Use

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.
