Vent-A-Hood 12-Inch Round Multi-Blower Transition

The Vent-A-Hood 12-Inch Round Multi-Blower Transition is an accessory designed to create a cleaner duct layout by converting an 8-inch and 8-inch dual-outlet configuration into a single 12-inch round duct connection. Vent-A-Hood’s installation documents identify VP563 as the multi-blower transition for this setup.

Vent-A-Hood specifically lists the VP563 for B400 applications using double B200 dual blowers, and its model specification pages state that the VP563 transition centers the outlet over the top of the hood. That makes the strongest accurate positioning for this product a Vent-A-Hood transition for compatible 1200 CFM multi-blower configurations where a centered 12-inch round duct connection is needed.
