THE ULTIMATE FIXED AIR GAP SYSTEM FOR FLOOR DRAINS & SANITARY FLOOR SINKS

The first and only fully-integrated, fixed air gap drain system on the market.

Wholesale Product Group introduces the DrainGapⓇ FS™ – a fully integrated, code-compliant air gap drain system designed to meet the rigorous demands of commercial and institutional environments. With this complete solution, we deliver everything you need for reliable, high-performance drainage in one certified package. 

The system comes with a 12" x 12" sanitary floor sink, a ready-to-connect trap primer port, a 3/4" outlet hub, an internal disposable strainer, and a durable 9" x9" modular PVC grate. At the heart of the system, the DrainGapⓇ FS™ offers flexibility with two certified air gap module options: a five-input 2" window model or a two-input 4" window model – both rigorously tested and certified to ASME A112.1.2, A112.6.3, and A112.6.7 standards. 

For expanded capacity, a dual-frame grate option allows the installation of two air gap modules within the same floor sink--ideal for muti-line drainage setups. Every component is engineered for code, compliance, safety, and ease of inspection, so you can spec it, install it, and move on with confidence.
