Elmo Rietschle V-KTR 81 – dry-running rotary vane pressure and vacuum pump
The V-KTR 81 works as a compressor and as a vacuum pump: 66 m³/h at 50 Hz and 82 m³/h at 60 Hz (referred to the state at the pressure connection), pressure up to +0.6 bar and ultimate vacuum down to −0.6 bar (rel.). It runs dry, i.e. without oil in the pumping chamber. Air cooling, inlet filter and vacuum and pressure regulating valves are standard; according to Elmo Rietschle, the rotor is supported on both sides and the flange-mounted motor is connected via a torsionally flexible coupling.Motor and dimensions
