The Rotary Vane Vacuum Pump RC 66 has been designed to minimise the adverse effects of condensable and corrosive vapours. Its main components are a two-stage rotary-vane pump and a two-stage chemistry diaphragm for optimited corrosion resistance. The diaphragm pump continuously evacuates the oil reservoir of the rotary-vane pump in order to keep the partial pressures of solvent vapours, oxygen and corrosive gases at a low level and/or below their condensation point. The RC 6 is a low-maintenance pump for freeze-drying and other applications requiring an ultimate vacuum in the 10-3 mbar range. Items supplied: Pump with on/off switch, overload circuit breaker and 2m cable with plug, centering and clamping ring for inlet, particulate filter and operating instructions. Oil supplied in separate bottle.
