This Gast Portable Rotary Vane Vacuum Pump is in used condition, has been tested and is guaranteed to be functional. This unit came from a local lab that had surplus equipment and shows signs of use. Unfortunately the pump no longer has the identification plate indicating model. We urge customers to view all photos as they show overall condition, included accessories and functionality. Please feel free to contact us with any questions. PLEASE NOTE: Aside from aesthetics, one issue worth noting is the left side gauge is no longer working and will need to be replaced. There is a chance we have the replacement so please inquire at time of sale.
