 Product Features: 
 1, the overall cylinder structure 
 Using integral cylinder block structure over the VRD series products, from the structure to ensure the accuracy of the cylinder and the deformation of the vacuum pump, while the top surface cut point arc design, the limit of vacuum stability. 
 2, built-in pump cycle is forced into the oil system 
 Over the VRD series of products using the built-in pump cycle to force oil into the system, forced lubrication of the pump chamber, and thus efficiency inlet pressure for the case of atmospheric pressure to work long hours. 
 3, auto return oil valve structure 
 Flying over the VRD series with automatic anti-return oil valve structure can be automatically cut off when the pump stops, the pumping system to ensure that the vacuum of the system and not be contaminated. 
 4, adjustable solar terms town design 
 Flying over the VRD series is equipped with adjustable solar terms the town to ensure a strong water vapor capacity, the effective exclusion of condensable gases.
