RECTANGULAR DAMPER SELECTION
Rectangular Damper Capacities*
* These air quantities were derived from duct sizing chart . 1" friction loss per 100' of duct.
All CFMs listed are approximate.
For accurate selection use duct sizing table or device.
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 damper is equipped with a damper board designed to support and
communicate with a Zonex wireless programmable thermostat. The D-Fuser is a fully
modulating power open / power close damper using a 24vac 60Hz 2 VA motor.
