Roots vacuum pumps RUVAC, which are also called Roots blowers, are rotary
plunger type pumps where two symmetrically shaped impellors rotate in opposite
directions inside the pump housing. Roots pumps are use where great volumns
have to be pumped. In combination with backing pumps, which compress against
the atmosphere, these pumps are capable of improving the attainable ultimate
pressure of a pump system by a factor of 10.
