VDN401 oil rotary vane vacuum pump has the following main features:

■Realized low noise. Low noise is achieved due to thorough low-noise design and precise processing.

■Excellent maintenance and repair performance. Because the main part of the pump can be removed without dismantling the connecting pipes between the vacuum pump 

and other equipment, cleaning, maintenance and replacement of oil seals, etc. become very easy. In order to make daily maintenance work convenient and easy, 

the direction of oil quantity confirmation, oil replenishment and oil replacement is in the same operating direction.

In order to extend the replenishment period of the used oil, a variable oil volume method of 1.0 to 2.5 liters is adopted.

■Capable of continuous operation in the full pressure range. It adopts a forced oil supply method that enables stable operation even at high suction pressure. By using an 

oil mist filter, oil recovery device and heat-resistant seals, it can operate continuously within the full pressure range below atmospheric pressure.

use:

■Coating, sputtering, ion plating.

■Gas replacement, filling, vacuum insulation.

■Vacuum drying, freeze drying, vacuum degassing

■Analytical instruments and leak detection devices.

■Vacuum packaging and vacuum adsorption.

■Transportation, vacuum forming, vacuum casting, etc.
