This will help reduce the iron oxidation that occurs, in the control valve, on air over media systems.
The Air Blocker will extend the valves' service life and cleaning intervals, over systems without an air blocker.
It is designed with the twist-lock feature that has an o-ring seal and will only work on Clack 1” control valves with 1.050 riser pilot.
NOTE: This should never be used on systems with Carbon as the media.
You need a Top Distributor attached to valve with carbon systems,
and this Air Blocker would prevent using the Top Distributor.
