ZJ Series Roots Vacuum Pump
ZJ series Roots vacuum pump
This series of Roots-type vacuum pumps cannot be used alone. It needs to be used in series with the pre-stage vacuum pump to increase the pumping rate of the pre-stage vacuum pump when the pressure is lower than 1.3×103~1.3×10-1 Pa. The structure is composed of two 8-shaped rotor sections and a rotor casing, and the two rotors do not contact each other and rotate in opposite directions in synchronization with each other.
ZJ series Roots vacuum pumps are mainly applied to:
PVD coating, magnetron sputtering, ion plating, optical coating etc;
Single crystal furnace, polycrystalline furnace, sintering furnace, annealing furnace, quenching furnace etc;
Vacuum drying, freeze drying, leak detection system, gas recovery system, liquid crystal injection etc;
Vacuum industry such as refrigerators, household air conditioners, central air conditioners, automatic evacuation lines for backlights, and exhaust equipment.
