4320 m³/h Vacuum Evacuation System for Transformer Maintenance
The 4320 m³/h Vacuum Evacuation System is designed for fast vacuum extraction in transformer maintenance, vacuum drying, vacuum oil filling and industrial vacuum processing applications.
- Complete Electrical Protection: Protects against phase loss, overvoltage, undervoltage and leakage, with alarm indicators for quick fault checking.
- Anti-Backflow Safety Design: Automatically helps prevent vacuum pump oil from flowing back into GIS equipment or vacuum chambers.
- Improved Roots Pump Cooling: Reduces pump temperature and supports stable high-capacity vacuum extraction.
- Optional Synchronous Start: Allows the vacuum pump and Roots pump to start together for shorter evacuation time.
- Wide Vacuum Range: Supports fast pumping across different pressure stages with deeper ultimate vacuum performance.
- Simple Control System: Easy-to-use control panel, with optional PLC and touch screen control for automation.
- Reliable Vacuum Connections: Stainless steel hoses and quick flange connectors support easier installation and better sealing.
This Vacuum Evacuation System is a high-performance vacuum pumping system designed for 4320 m³/h fast vacuum extraction in transformer maintenance, vacuum drying, vacuum oil filling and industrial vacuum processing. It is especially suitable for power equipment such as transformers, where stable vacuum performance is required before oil filling, drying or maintenance work.
it adopts a combined Roots pump and vacuum pump design, providing large pumping speed, fast start-up and strong vacuum extraction performance. The working vacuum can reach less than 133Pa, while the ultimate vacuum can reach less than 5Pa.
To ensure stable long-term operation, the system is equipped with an electrical control system, automatic vacuum relay, cooling water system, vacuum pump oil circulation filter and circulating water cooling device. These configurations help protect the vacuum pump, reduce aging, maintain normal pump temperature and improve operation safety.
For projects requiring larger extraction rates, the system can be customized with dual Roots pumps to achieve faster pumping under high-vacuum conditions.

Transformer Vacuum Extraction
Used to evacuate air and gas from transformer tanks before oil filling, drying or maintenance.
Vacuum Oil Filling for Transformers
Creates a stable vacuum environment before transformer oil injection, helping reduce trapped air and bubbles.
Transformer Vacuum Drying
Supports vacuum drying processes by lowering pressure and helping remove moisture from power equipment.
Power Equipment Maintenance
Suitable for transformers, reactors and other electrical equipment that require vacuum treatment.
Industrial Vacuum Extraction
Can be used in general industrial vacuum systems where air removal and stable vacuum conditions are required.
Vacuum Metallurgy, Chemical and Petroleum
Also applicable to vacuum metallurgy, chemical processing, welding and petroleum-related vacuum systems when the required vacuum level matches the equipment capacity.
Optional Configuration
Germany Leybold Vacuum Gauge
Germany Robert RBT Ball Valve
Double Zone/Single Zone Micro NC Vacuum Gauge
