Rotary claw vacuum pumps with variable speed drive

They are rotary lobe pumps characterised by suction or compression of air without contact between the parts, no sealing fluid in the suction/compression chamber, air cooling, energy saving. They have been developed for use in industrial sectors where medium to low vacuum, low maintenance and at the same time oil-free exhaust air are required. They are available with a variable flow rate between 180 mc/h and 332 mc/h, reaching a final residual pressure of 200 mbar absolute.
