AirLoc™ Gravity Damper Whole House Fan Models
AirLoc™ gravity damper models include Summit Series 2.4, 3.4, and 4.9 whole house fans.
An economical choice in a whole house fan, VentCool Summit and Tahoe series attic fans feature AirLoc™ gravity damper models and are better suited for warmer climates since they do not provide an airtight seal nor is there an insulated barrier between the living space and attic. AirLoc™ gravity damper models can be used in colder climates but be sure the unit is sealed and/or insulated during the winter. Made with aluminum blades and a stainless-steel frame, gravity backdraft dampers are the most cost-effective choice in preventing the reversal of air flow. At VentCool, we have a selection of whole house fan models in various sizes that include a gravity backdraft damper to suit your needs. For more information and help discovering the high-performance gravity damper model that’s perfect for your needs, feel free to contact us at 252-522-3031.
16 Inch on Center Installation.
VentCool Whole House Fans are installed from inside the attic and designed to fit between the joists. There is no need to cut joists when installing the damper box since they all fit 16” on center. Installation is simple. Experienced installers will find installation is fast so there is less time spent on the job site. Homeowners who are handy do-it-yourselfers can easily install a VentCool fan themselves.
All VentCool Whole House Fans include
- An AirLoc™ or PowerSeal™ damper (depending on the model)
- 7 feet of noise reducing flexduct (except for Vista 1.7)
- Wall mount control switch
