The AG100-002 Universal Dual Airgap is designed to provide an effective way of connecting water filters to a drain line. The paramount priority of the AG100-002 is to protect the water supply from contamination by separating potable water supply from the drain line.

The AG100-002 features two 3/8" inlet ports that connect 3/8" tubing from water filters to the drain line. The unique feature of this air gap is to be able to accommodate 1-1/2" and 2" standpipes. In addition, a unique design of this air gap enables installation of multiple air gaps into the same drain connection. Up to three AG100-002s can be installed into the same drain line to provide a total of six simultaneous water discharge connections. Splash guard plates protect adjacent equipment from moisture.

The AG100-002 air gap is listed by UPC® and tested for compliance with IPC® and NSF® standards.
