Re: Fantastic Fans in Penthouse Top
Not sure I need one yet. But the "small vent" Fantastic fan is a very quite variable speed 10 blade low draw fan that really moves air. We also have for many years used a screen house that walls are 100% screening. In still hot weather with some sun the inside was still noticeably hotter then the air outside. Many times in the northern woods you can hear the wind in the trees but at ground level the air can be very still.
At high speed the fan draws about 920cfm which should be about 1.5 air exchanges per minute. So on hot, humid, still nights the fan may be a very positive addition. Also the fan is "free" since I already own two!
