  • What's Included
  • This 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 performed repeatedly 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.

    So far the booster fan works well and it was simple & straight forward to install. Happy with it up to this point... I'm curious to see the longevity of this product.
