Compressed Air Piping Loss & Prevents
Costly Drain Problems:


Airid's Moisture Minder E-Drain Valve (valve + timer) is now available with full on-board controls.  This drain valve is designed with the near-zero air loss feature of our standard Airid Moisture Minder product, along with a built-in timer.  The new Airid Mositure Minder is ideal for all drain operations (Receiver Tanks, Drip Legs, Separators, Dryers, Aftercoolers).  This drain valve kit is internally pilot operated with cycle time adjustability from 1 to 120 minutes.


As with all other Airid Moisture Minder products, this one will outlast any other drain product available today.  Moisture Minder kits, operating at 1 minute drain cycles, are still in service after 20 years!
