Featuring a maximum flow rate of 1 GPM, precision tubing compatibility, and tested durability exceeding 40 pounds of force, it ensures a splash-free, secure, and code-compliant installation for both residential and commercial use. ## Description The AG110-002 reverse osmosis (RO) filter air gap prevents backflow from the standpipe into the RO system. This unit is a gravity flow device and, as such, must have a standpipe feeding directly to a drain without kinks and bends. The GAP-A-RO air gap’s maximum flow rate is 1 gallon per minute (GPM). The maximum flow rate through an air gap is the flow rate at which water does not splash outside an air gap. The air gap is dry on the outside at the maximum flow rate. The AG110-002 air gap must be installed per the manufacturer’s instructions, and the outlet side feeding directly into a standpipe. This configuration lets the discharge water stream flow freely through the outlet piping. The inlet port fits 1/4-inch OD poly tubing from the reverse osmosis unit, and the outlet port fits 3/8-inch OD poly tubing directly feeding into a standpipe. The AG110-002 air gap provides the following advantages: Super strong material to provide a secure connection, tested and listed for compliance with applicable plumbing codes, is easy to install, easy to use, and easy to maintain. ## Features - ❤ FLOW RATE: The GAP-A-RO air gap’s maximum flow rate is 1 gallon per minute (GPM).
