Air King Introducing most efficient fan?
I was mulling around on the Energy Star website and came across a listing for an Air King in-line fan. Curious, I checked out their website and also found they have a new line of DC motor exhaust fans coming to market.
According to a page on the 2017 AHR Expo website, these new Air King D4S and D4D fans will be the most efficient exhaust fans on the market:
According to the company’s Ventilation Catalogue, these fans will have a selectable airflow range of 30-120 CFM, a peak power input of 7.3W, and self regulation to ensure consistent airflow with various restriction levels.
120cfm / 7.3W = 16.4cfm/W
How does that stack up to other options? I’ve only heard reference to Panasonic’s Whisper fans, and I’m not intimately familiar with their lineup.
