The Rotary Vane Vacuum Pump RC 6 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 optimised 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.Scope of supply: Pump, overload circuit breaker and mains cable (2 m), centering and clamping ring for inlet, particulate filter, operating instructions, oil (bottle of 500 ml)Country-specific power cord versions available on request.

The dry-compressing multi-stage roots vacuum pump was specially developed for applications that require short pump down times, low noise levels, low vibration, and no particulate generation, such as analytical instruments, research laboratories, and light industrial processes. The friction-free operating principle protects its components from any wear, and all components are designed for an operating life of up to five years. During this time, maintenance measures such as replacing seals or changing the oil are not required. The pump is also air-cooled and therefore requires no connection to a water supply for cooling.Integrated castors make it easier to transport the pumpSilencers and integrated acoustic insulation ensure a very low noise levelClean vacuum generation without contaminating the workplace and recipient thanks to the oil-free suction chamber and contact-free rotorsHigh water vapour toleranceIntegrated control panel offers the option of connecting vacuum gauges and valves directly to the pump for simple pressure and valve controlSwitchable mains voltage 100 to 127 V/200 to 240 V, 50/60 Hz
