Clack D1047 WS1 Air Blocker
Use with Ozone and AIO systems
Air Blocker traps water in its chambers, blocking the head of air in the tank from entering the control valve, reducing iron oxidation in the valve.
Extends service life and cleaning of control valve internals.
Air Blocker is designed to twist lock (O-ring seal) into the control valve’s threaded base.
Air Blocker will only work on Clack control valves
