ZJ-300
1000m3/h Industrial Vacuum Processing Machine
- The YUNENG1000m3/h industrial vacuum processing machine has a fast start-up speed and fast air extraction.
- It is especially suitable for the vacuumization of transformers.
- It can also be used for vacuumization in vacuum metallurgy, pharmaceutical, paint, welding, electronics, and other industries.
- It can also be used as a backing pump for large vacuum systems.
The ZJ-300 is an industrial-grade vacuum station for medium transformers up to 220 kV. It features a high flow rate and strong evacuation capacity, ideal for factory production and large on-site maintenance tasks.
The unit supports stable 24/7 operation. It integrates a dedicated GIS vacuum interface for professional vacuum treatment of GIS equipment in high-voltage substations.
