The Air-Saver is installed on the air outlet of the air tank. The Air-Saver will automatically open just prior to the working shift begins, and closes just after the working shift is over.
A typical compressed air system will lose compressed air through pipe connections, non-demand drains etc. At the end of the final work shift, the Air-Saver will shut the air tank off from the rest of the system. The content of compressed air within the air tank will be saved rather than lost through pipe leakages.
