1. It is designed to extract air from transformer. 2. vacuum drying for transformer. 3. made of two vacuum pumps.
ZJ air extractor Feature:
(1) Quick starting, high pumping rate, stable performance, easy-handling.
(2) The unit takes Roots Pump as main pump and spinning vacuum pump as pre-stage pump.
(3) A vacuometer is used to meter and control vacuum of pumped container.
(4) The unit adopts French Schineider Electric as control element.
(5) Full-automatic and non-presence of operation with lamps indicating the condition of operation.
(6) Humanization design, low noise, less energy expenditure, economical to circulate cost.
