The vacuum negative pressure station is equipped with a gas-water separator, which can save water and reduce environmental pollution.

The vacuum tank of the device can be designed horizontally and vertically according to the field design, and the installation is more flexible.

The device adopts the advanced automatic water replenishing device in Japan, which does not require manual water replenishment, and greatly prolongs the life of the equipment.

The device automatically controls the system without human operation, and automatically closes the vacuum system during power failure.
