A: This unit does have a length of 14 inches. However, they require a rough opening of 14-½” x 22-½”. Because of this rough opening requirement, it sounds as though your area will be too small to accommodate. The damper assembly box is designed for horizontal installation only. The dampers will not function in the vertical position. If you have any further questions, please call us at (800) 433-1626.
A: Hello Ki, our 14" ducted whole house fan does not include a reverse option.
A: I would say NO...It has an R-5 insulated backflow damper at the ceiling but I see where it may be an issue since many jurisdictions are requiring thermal break to meet current prescriptive r-values in the energy code. That said, you will want the fan in the attic to reduce noise where it will pull the air out versus pushing exhaust air against the damper which would create more fan noise. You may want to look at the Battic Door version that has an R-50 motorized door and even a wifi control to meet your needs and possibly even code compliance with a thermal door.
A: Hello GarageMan, our 14" ducted whole house fan is rated at 6.6 sones at 1289 CFM on low speed. We rate our attic fan noise in sones instead of decibels for a more accurate rating.
A: Mine said 3500 CFM on the paperwork and the side of the box. There are multiple sizes so make sure you get the one you need.
A: Hello Rich, the CFM rating for our 18" ducted whole house fan is 2700 CFM.
