Gas Automatic Switching Box

Model ZQ-1 gas automatic switching box is widely used in hospital, industrial enterprises or scientific and research institute where central and uninterrupted gas supply is needed. It can divide a lot of gas cylinders into two groups and gather gas from all cylinders together to transfer to all special gas-consuming equipment via pipes after pressure regulating and stabilizing. 

When it is in operating, it uses gas in one group of cylinders. In case gas in the group is almost exhausted it can automatically switch to the other group of cylinders under normal gas-supply state and send out sound and light alarm signals to tell operator on duty to change air source and adjust switching handle thus to ensure uninterupted gas supply and ready use of cylinder with full gas.

This automatic switching box has advantage of reasonable structure, convenient, safe and reliable operation and service.
