  • Make your existing HVAC system more effective by increasing air flow with this duct booster fan. The fan features a 115 VAC power cord and built-in Pressure Response Control (PRC) unit to automatically operate when your forced air system is running. When positive pressure is sensed, the PRC turns the fan on to channel the hot or cool air into the selected room. Pressure checks are automatically performed to determine whether the fan should continue to run. The fan will even continue to run for a short time after the heating or cooling system has turned off to ensure every last bit of the heated or cooled air makes its way out of the duct.

    Heavy gauge steel housing and metal prop fan blades make this duct booster fan ultra-durable. If installed where your system's filters are properly positioned and maintained, this fan or its motor will not require any cleaning. The fan's operation will be so smooth and quiet you might forget that it is running.

    Works as designed. It is louder then I expected.

    The unit is about 2 feet from the trunk line and is still very loud. Also, pressure switch is not sensitive enough and you have to give it an assist to start the fan.

    Save your money, do not buy. Got this fan hoping to boost airflow to a duct in bedroom. Hooked up per instructions, this booster made plenty of noise but did not help at all. In retrospect, I should have bought a more powerful booster with a separate switch. Avoid this one !!

    I bought this booster fan about 4 months ago because my home office was always colder in the winter and warmer in the summer than the rest of the house. It was at the end of the line and just didn't get enough heat or A/C.
    The install was easy. Took less than an hour.
    Now that I've had a chance to experience it working both with A/C and heat, I have to say, it's amazing. For my purposes, it was well worth the price. I can hear it running but it's not loud I actually like that I can hear it so I know when it's on. Occasionally, it will kick on when the strong Santa Ana winds blow, but that's not very often. I guess gusts of wind get in the system and trigger the switch.
