Edwards RV12 Rotary Vane Vacuum Pump – 8.4 CFM, 115/230V 1-Phase 50/60Hz (Factory Set to 115V for USA) (A65501906)
Edwards RV12 Two Stage Rotary Vane Vacuum Pump – 8.4 CFM
The Edwards RV12 (part number A65501906) is a versatile two-stage oil-sealed rotary vane vacuum pump from the highly regarded RV series. This single-phase model is factory set to 115V for USA operation (switchable to 230V) with 50/60 Hz compatibility, making it plug-and-play ready for most North American laboratories and light industrial facilities.
With a pumping speed of 8.4 CFM (14.2 m³/h) at 60 Hz and an excellent ultimate vacuum of 2 × 10⁻³ mbar, the RV12 offers high throughput, outstanding vapor handling, and quiet performance. The RV series is known for its ability to deliver excellent ultimate vacuum in both high-vacuum and high-throughput modes, with or without gas ballast.
