EDCO Vacuum pumps with manual valve (MV) option provide a compact compressed-air powered control unit for vacuum workholding fixtures. An easily-readable 1-1/2” vacuum gauge displays depth of vacuum within the system so a technician can determine whether an adequate vacuum level has been achieved based on experience. This pump incorporates the bowl, gasket, and filter element of our t-style filters directly into the pump base eliminating the necessity of incorporating an external filter into the vacuum system.
