D-FUSER ZONE DAMPER
Zonex Systems D-Fuser is a combination zone damper and diffuser. It mounts in a standard 2’ x 2’ T-bar
ceiling opening, providing for simple installation and easy maintenance access. The D-Fuser is a cone
shaped fluidic nozzle with a platen that modulates up and down to control air flow. As the platen moves up,
the air volume is reduced; but the air velocity and throw remain constant. This keeps the air hugging the
ceiling, which maximizes room air mixing and minimizes the “waterfall” effect. The D-Fuser is a fully
modulating power open / power close damper using a 24vac 60Hz 2 VA motor. Motor drive time from full
open to full close is 90 seconds. The D-Fuser connects to round duct either on the side or top. Collars are
available for 6”, 7”, 8”, 9” and 10” duct.
