The Edwards RV3 is a two-stage, oil-sealed rotary vane vacuum pump renowned for its versatility, high performance, and quiet operation. Designed to accommodate both high vacuum and high throughput applications, it is widely used in laboratory and industrial settings.

Key Features:

• Selectable Dual Mode: Offers high vacuum for optimal pressure and high throughput for continuous inlet pressures above 50 mbar, allowing users to select the most suitable pumping performance for their applications.
• Gas Ballast Valve: Equipped with an easy-to-use gas ballast valve, the RV3 can handle water vapor pumping rates of up to 220 grams per hour, making it ideal for applications involving moisture and solvents.
• Quiet Operation: Operates at a noise level of 48 dB(A) at 50 Hz, providing a quieter working environment and minimizing disruptions.
• Mode Selector & Gas Ballast Control: Features a simple mode selector and accessible three-position gas ballast control, allowing the pump to be reconfigured at any time, even during operation, to meet varying vacuum needs.
• Fast-Acting Inlet Valve: Incorporates a fast-acting inlet valve that seals the pump to prevent oil mist from entering the system, ensuring safe operation and protecting connected equipment.
• Maintenance-Friendly Design: Designed for easy maintenance, the RV3 requires minimal servicing, reducing downtime and ensuring reliable performance over time.

Specifications:

• Pumping Speed:
– 50 Hz: 3.3 m³/h (2.0 CFM)
– 60 Hz: 3.9 m³/h (2.3 CFM)
• Ultimate Pressure:
