Combined with dry or oil-sealed forevacuum pumps, RUVAC roots pumps are used effectively to increase the pumping speed at low pressures,  extending the operating pressure range of the fore-vacuum pumps. The RUVAC WA series uses air cooled, flange-mounted standard three phase motors

• RUVAC roots pumps can be used either in vertical or horizontal position, thus ensuring flexibility in achieving compact design within systems. Position selected may be changed later if required.
• RUVAC roots pumps have rugged bearings, which in combination with the highly efficient lubrication systems enhances quiet running properties.
