                The PVL Series rotary vane vacuum pumps are a superior and well "Proven Design". Air-cooled and direct-coupled monoblock designs offer one of the industries most reliable choices in rotary vane vacuum technology. A compete range of standard factory engineered systems to custom designs are available including medical vacuum NFPA99.

                Roots vacuum pump

                A roots vacuum pump is a vacuum pump that compresses and exhausts by rotating a helical rotor.
                This mechanical vacuum pump is also referred to as a mechanical booster when it is mounted to the front end of an oil-sealed rotary vacuum pump to increase the exhaust rate.
                A roots vacuum pump is normally used with a vacuum pump that can compress up to atmospheric pressure, such as a dry vacuum pump, oil-sealed rotary vacuum pump, or a liquid-ring vacuum pump.

                Osaka Vacuum's roots vacuum pumps with directly mounted motor (RD series, RA series) feature a compact footprint for easy integration into existing systems.
                Our lineup also includes belt-driven large roots vacuum pumps (R series) suitable for applications requiring heavy exhaust volumes such as for oversized chambers used for aerospace testing.

                An operating condition of the roots vacuum pump is that there be an allowable pressure difference between the inlet pressure and back pressure. Operating outside the allowable range may result in motor overloads, or excessive uncontrollable heat.
                To address this, roots vacuum pump exhaust systems from Osaka Vacuum can be fitted with a relief valve to automatically adjust the pressure if it exceeds the allowable range. This enables the pump to perform at maximum exhaust capacity even in high inlet pressure ranges. (Optional)

                Inverter control allows driving from atmospheric pressure, and pressure control at low inlet pressure levels.
                Also, depending on the model and region, the speed of the pump can be increased to increase the exhaust rate by a maximum of up to 40%. (Optional)
