The Edwards RV12 is a two-stage, oil-sealed rotary vane vacuum pump renowned for its high ultimate vacuum, substantial pumping speed, and efficient vapor handling capabilities. Designed for both laboratory and industrial applications, it offers reliable performance with quiet operation.

Key Features:

• High Pumping Speed: Delivers a pumping speed of 12 m³/h (7.06 CFM) at 50 Hz and 14.2 m³/h (8.35 CFM) at 60 Hz, ensuring efficient evacuation of air and gases.
• Ultimate Vacuum: Achieves an ultimate pressure of 3.0 x 10⁻³ mbar (2.25 x 10⁻³ Torr) without gas ballast, suitable for applications requiring deep vacuum levels.
• Vapor Handling: Equipped with a gas ballast valve, the RV12 can handle up to 290 g/hr of water vapor, making it ideal for wet pumping applications such as freeze drying, extraction, filtration, and gel drying.
• Quiet Operation: Operates at low noise levels, providing a quieter working environment.
• Anti-Suck Back Protection: Features a fast-acting inlet valve that closes within 0.4 seconds of the pump stopping, preventing oil mist from entering the system and ensuring safe operation.
• Flexible Operation: Includes a mode selector and two-position gas ballast to meet varying vacuum needs, enhancing versatility across different applications.

Specifications:
• Motor Power: Operates on 115/230V, 50/60Hz, 1-phase electrical supply.
• Cooling Method: Utilizes convection cooling for efficient thermal management.
