Roots screw unit:

The roots screw unit is a combination of a roots pump as the main pump and a dry screw pump as the backing pump, equipped with a filter and a control box, becoming a new type of vacuum pumping equipment.This unit will make up for the insufficience of original vacuum pump.

Roots screw unit advantages:

Increase pumping capacity -  a Roots vacuum pump can increase the total (instantaneous) pumping capacity.

Increase the service life - roots vacuum pump can reduce the temperature rise of the vacuum pump,making the pump no overheat; can reduce the running time of the vacuum pump; if adding a buffer tank and air filter,it can reduce foreign matter and micro-granular solids into the vacuum pump.

Solving pollution - can solve the problems of  pollution,waste gas recovery,etc., which is caused by traditional unit. Threfore, it has great advantages in the pharmaceutical, chemical and other industries.

Roots screw unit application range:

The vacuum unit is suitable for environmental protection and clean application processes in the pharmaceutical, chemical, electronics and other industries.
