TWISTER S-VSA / S-VSB / S-VSI series

With the screw vacuum pumps of the S series, compression is achieved by reducing the space inside. The screw vacuum pump consists of two parallel rotors in the shape of a screw, one screw having a right-hand thread and the other a left-hand thread. Both screws mesh without contact and with very narrow gaps in the compressor housing.
