1. 2X rotary vane vacuum pump is of double-stage oil-sealed mechanical vacuum type and is the primary equipment to create vacuum for sealed vesselsby air extraction. Remarkably, this type of pump has become the leader in market with its unique and excellent performance,providing the following features:
fast extraction,compact size,light weight,low noise,easy mainainance and creation of high vacuum degree.
2. It is equipped with a reliable dust filter. Impurities may get into the inside of other types of rotary vane pump.
3. It has a dual-purpose screw serving as both release valve and oil inlet. Other double stage rotary vane pumps that have been in production for many years in China are so designed that the oil inlet is located in the air relief valve seat at pump inside bottom, so that to clear away any blockage in the oil inlet need to drain out the oil and remove the oil tank.
