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
and throw remain constant. This keeps the air hugging the ceiling
which maximizes room air mixing and minimizes the “waterfall” effect.

These air quantities were derived from a duct sizing chart .1” friction loss per 100’ of duct. All CFMs listed are approximate. For accurate selection

flow. As the platen moves up, the air volume is reduced but the air velocity
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.
