Essential Info

Designed for installations that will not accommodate standard in-line Duct Booster fans, this register fan installs directly into your floor and delivers hot or cold air from your HVAC system. Installation into existing register boots only takes a few minutes. No hard-wiring is required; simply plug the attached 6-foot power cord into the nearest electrical outlet. The air flow will instantly be strengthened and the booster fan will operate quietly to not distract you from your task at hand. The fan's low sone cross flow blower enables it to be 50% quieter and eliminates buzzing that can be heard from typical booster fans. An on/off toggle switch lies beneath the grille to turn the unit completely off when you don't want it running.

    This product was easy to install and made a big difference in our upstairs cooling! Very quiet operation as well. I would recommend this duct booster and Smarthome is great also!
    sam -- Seattle   8/29/2013
    It's OK as long as you don't have zone dampers, because if the zone damper closes while the fan is running, it gets very loud and vibrates like it won't last long.

    You get what you pay for. Great motor, very quiet. Made a noticable difference in my upstairs loft (open to downstairs) where my single-zone A/C can not keep both levels at a comfortable temperature. I do not have access to the ducts to install internal duct booster fans and I don't have the money to install a second-zone A/C for upstairs. Cooled my upstairs enough that I don't have to run the ceiling fan as much. I highly recommend this power register as a 1st step in any attempt to even the temperarure between floors.

    work good, little bit loud, expensive

    Very well engineered product. The quality is very good with only a low level of noise.
