Roots vacuum pump with good quality and very competitive price
Product Description
Roots vacuum pumps
As mechanical type vacuum pump equipped with a pair of dual-leaf rotors
rotating in high speed,roots vacuum pump can realize the gas intake and
exhaust by the rotation of the two figure-eight shaped rotors in pump
housing. The operating principle is similar to that of roots blower.
Because the pump is operated in low pressure range, which with the long
free path of gas molecule and the great resistance of gas leaking
through micro gap, high compression ratio is possible. The pump can be
used as booster device; however it cant exhaust gas into the atmosphere
directly,and should be used in connection with backing vacuum pump.The
pumped gas can be released into atmosphere via the backing vacuum pump,
