AC Infinity AIRTAP T6, Quiet Register Booster Fan System, Bronze, for 6" x 12" Registers

I cut a hole in the floor above a woodstove (located in the basement). I purchased the Register Booster Fan to help pull the heat from the woodstove. The Register has two fans but they don't seem to move much air even on the highest setting. Might work great for other applications. Good quality and noise was not an issue.

We need a boost in air flow to the most used room in our house and these registers work perfectly. The fan sensor was a bit difficult for this non-IT Savvy geezer to set. I stayed with the instruction and finally found MY mistake in reading the instructions. We LIKE the way it works automatically.

Tight fit, not the simplest to program but once configured these improve airflow in a room without having to run the full HVAC blower all the time.I have used both the cooling feature as well as the fan manually on at a set speed, heat boosting is not required for this room(but could be a way to combat a poorly insulated room's temperature difference. pulling more cooled air in summer and warm air in the winter.Thermostatically controlled to turn on when air temperature in the duct is above or below a set point. I use them to pull more cool air from the duct and other rooms through a room with lots of light and solar heating. I was worried about our Master suite getting too cold but that isn't an issue. As well as there is not much restriction on air flow when fans are not running so no need to remove them when additional airflow is not required.Yes, these are 6x12 and sit down in the duct almost 2 inches. For my installation, this required trimming the carpet and making sure the duct opening was fully open. While a very tight fit, they do not require any additional mounting to avoid rattling or vibrations when running.The long-life fans move a good amount of air relatively quietly, (a lot quieter than a box fan or table fan, but not fully silent, the HVAC blower on high is still louder)After locking the controller and turning off the LED display, the LEDs will turn back on after power loss, and do not go back dark automatically. (but the operating configuration does not reset after a power cycle)

Very tight fit, low noise, easy installation, and moves air very well to increase or decrease temperature rapidly.

2 Minute install fixed a hot room. Simple, quick and easy solution. Getting one more for hot spot in house.
