RS-4 single stage rotary vane vacuum pump

一、Characteristic：

1, anti return oil design

The air inlet channel is specially designed to prevent the back flow of the pump oil after stopping the pump, and the pollution is drawn and the pipeline is discharged

2, environmental protection design

The oil tank is arranged in the interlayer, and the oil and gas separation device is arranged on the exhaust port

3, aluminum alloy motor casing

The motor is made of aluminum alloy shell, which has high efficiency of heat dissipation efficiency, ensures long time continuous operation, and has good appearance quality

4. Integrated design

Integrated with the pump design, make the product more compact and reasonable

5, large starting torque

This product is specially designed for low temperature environment, to ensure the normal start in the case of low ambient temperature in winter

6, the use of shock resistant rubber foot, reduce vibration and noise.

二、purpose：

1..RS-4 type rotary vacuum pump is connected directly to the micro vacuum pump

2 for the special design of low temperature environment, to ensure the normal start in the case of low ambient temperature in winter.

3 optimization design, the increase of the vacuum, the efficiency is improved, suitable for vacuum refrigeration, automobile maintenance, medical machinery, vacuum packaging, gas analysis, printing machinery and other vacuum pumping.
