Mainly used to evacuate GIS (Gas-Insulated Switchgear) and other high-voltage electrical equipment, creating the required vacuum conditions before filling with SF₆ or other insulating gases.
- Complete Protection & Alarm System – Provides phase sequence, phase loss, overvoltage, undervoltage, and leakage protection with fault indicators.
- Automatic Vacuum Control – Allows users to preset the target vacuum level, with automatic start and stop based on the set value.
- Timed Operation – Supports preset operating times and automatic shutdown when the set time is reached.
- High-Efficiency Dual-Pump System – Atlas vacuum and Roots pumps start simultaneously, improving evacuation efficiency by 30%–50%.
- High Vacuum Performance – Achieves an ultimate vacuum level of below 5 Pa.
- Anti-Oil Backflow Protection – A differential pressure valve prevents vacuum pump oil from flowing back into the GIS chamber during shutdown or power failure.
- Optional PLC & Touchscreen Control – Enables fully automatic operation, remote start, and real-time monitoring.
- Complete Connection Accessories – Supplied with stainless steel vacuum hoses and quick flange connectors.
Zanyo Vacuum Extraction System working vacuum is less than 133Pa, the ultimate vacuum is less than 5Pa. The unit is fast starting and large pumping speed, etc. It can be used for vacuum extraction, applied in industries such as vacuum metallurgy, welding, chemical industry, petroleum and vacuum system, especially used for vacuum extraction in power equipment such as transformers.

- The machine adopts special Roots pump and vacuum pump, so the vacuum pumping speed and pressure, are obviously better than any other devices. ZYV equips an electrical control system and a cooling water system.
- It adopts automatic vacuum relay for automatic control.
- It equipped with vacuum pump oil circulation filter and circulating water cooling device, to ensure that vacuum pump oil is not aged, circulating water to keep the pump with normal temperature.
- If clients required larger extraction rates, we can equip two roots pumps, machine is available for faster extraction under high vacuum condition.
