Gardner Denver Z5941 Automatic Tank Drain Rebuild Kit

The Gardner Denver Z5941 Automatic Tank Drain Rebuild Kit is a restoration set for automated filtration valves that removes accumulated moisture from compressed air storage tanks in HVAC systems. This includes internal pieces such as a diaphragm, valve disc, spring, stem, and sealing elements that renew the drain assembly's operating action. Whole component is positioned within the valve body to regulate opening and closing cycles through pressure changes. Properly operation drain operation allows trapped condensation to discharge automatically, reducing moisture buildup inside the receiver tank and maintaining cleaner air flow through the compressed air system.
