As the rotor rotates two vanes, placed in rotor vane groove, turn making contact with the internal surface of the cylinder due to centrifugal force. The inhaled gas is trapped between two vanes as the rotating vane passes through the inlet passage and this trapped gas is compressed as it rotates toward exhaust valve and eventually exhaust through valve. The vacuum oil is supplied to the moving parts for lubrication and tight sealing.
Excellent ultimate vacuum and pumping speed by using high performance new materials. Improved oil anti-suckback system to protect the vacuum system in the event of sudden stop. Occupying strong and constant pressured oil circulating system to protect the pump. Simple maintenance and oil replacement. Simple repair without special tools.
