The ET120-001 Universal Air Gap is designed for home or commercial water treatment equipment and condensate lines that require an air gap discharge to the drain. This air gap drain line adapter is perfect for applications where rigid Schedule-40 pipe must be plumbed to an approved air gap device. The ET120-001 provides a convenient, ready-made, air gap for all Schedule-40 DWV standpipes.
The ET120-001's minimum flow rate is 6 gallons per minute (GPM) and the maximum flow rate is 22 gallons per minute (GPM). The minimum and maximum flow rates through an air gap are the lowest and highest flow rates at which water does not splash outside of an air gap. At minimum or maximum flow rate, the air gap is dry on the outside.
It is easy to use, easy to install, and easy to maintain. The ET120-001 air gap is UPC and IPC listed.
