The AG110 series Reverse Osmosis (RO) water filter air gaps are intended for installations with flows of 1/2 gallon/minute. This unit is a gravity flow device and as such must have a drain line feeding directly to a drain without kinks and bends.

The inlet port fits 1/4-inch poly tuning and the outlet port fit 3/8" poly tubing.
