Wonchang’s Dry Rotary Vane Pumps operate according to the rotary vane principal. The rotor is eccentrically positioned in the pump cylinder and has the machined slots for sliding of the vanes. The centrifugal forces of the rotation pushes vanes out towards the wall of the cylinder. The gas enters vacuum pump through the inlet manifold (Air filter) and is compressed and pushed out through the outlet manifold (built-in silencer) installed on pump module. The regulators installed on manifold are adopted for regulating vacuum or pressure level constantly. Carbon material vane is employed for self-lubrication.
