AFR Lifestyle 1 scaled

When it comes to maintaining a comfortable living environment and protecting your home from potential damage, having a reliable and efficient solution for attic ventilation is crucial. That’s why we are excited to introduce the all-new QuietCool AFR line of roof mount attic fans. This groundbreaking product line surpasses any other on the market today, offering unmatched performance, advanced features, and easy installation, making it the top choice for homeowners and professionals alike.

The Sealing Obsession

The solution lies in proper attic ventilation, which can be provided by whole house fans and attic fans. These fans cost only pennies per hour to operate, making them a cost-effective alternative. Furthermore, the price tag associated with spray foam insulation, ranging from five to ten thousand dollars, pales in comparison to the affordability of a whole house fan (typically $600 – $1400) or an attic fan (usually priced between $150 – $400).

Patent Pending Design

Designed with meticulous precision in the USA, the AFR fan features a one-piece, stamped steel hood without any seams or welds. This seamless design not only enhances the fan’s durability but also ensures optimal airflow within your attic space. Combined with high-performance computer-balanced fan blades, the AFR line effortlessly cuts through the air, maximizing efficiency and ventilation.


The AFR’s one-piece perforated cylindrical housing is not only visually appealing but also incorporates an integrated wildlife guard. This safeguard preserves the integrity of your attic by preventing bugs and other wildlife from accessing it while still allowing for optimal ventilation. The housing is coated with high-quality polyester paint, providing excellent film integrity and extreme UV protection. This guarantees longevity and resistance to harsh weather conditions.

The AFR line is powered by the best motors available. In the PRO models, you’ll find highly efficient two-speed Permanent Split Capacitor (PSC) motors, ensuring the fan operates at peak performance throughout its lifespan. The ES model features the world’s most efficient motor, the three-speed brush-free Electronically Commutated Motor (ECM). This groundbreaking motor technology boosts energy efficiency by up to 70% at lower speeds, resulting in significant energy savings without compromising performance. Whichever model you choose from the AFR line, you can enjoy a well-ventilated attic while minimizing your environmental footprint.

The AFR line offers exceptional versatility with its interchangeable flashings, seamlessly accommodating various roof types. The primary flashing simplifies installation on shingle roofs, while the optional secondary flashing eliminates the need for fabrication when installing on cement tile roofs. For S-tile or M-tile type roofs, the malleable aluminum design allows the secondary flashing to be easily molded to fit. Moreover, the AFR line offers the option to curb mount the fan to a flat or low-pitch roof using the curb flashing, with no need for fabrication. Interchangeable flashings are sold separately.

This plug-and-play design saves you time and effort during the installation process, allowing for a quick setup and immediate enjoyment of improved attic ventilation.

Custom Control

We recognize that every homeowner has unique needs, which is why we offer two control options for the AFR line. The adjustable thermostat, available in our most affordable model, allows manual adjustment from 50º to 120º, giving you precise control over your attic’s temperature. 


For our smart models, the innovative Smart Control option provides a host of advanced features. With the QuietCool Smart Control app, you can effortlessly monitor attic temperature and humidity levels, manually operate the fan, enable smart mode for automatic cooling and ventilation, and customize settings and presets to suit your specific requirements. Our patented Smart Mode ensures the attic remains at the ideal temperature and humidity conditions throughout the year, eliminating the need to climb into a hot attic to adjust the thermostat.


The Smart models feature built-in temperature settings that proactively cool the attic by increasing the fan’s speed as the temperature rises. This intelligent feature ensures optimal performance without constant adjustments, offering convenience and peace of mind. Additionally, the AFR line includes two pre-set options for Summer and Winter climates. These tailored presets optimize temperature and humidity conditions to help with cooling and ventilation in the summer, help prevent ice damming during winter, and combat condensation buildup in humid climates.


Safety is of paramount importance when it comes to attic ventilation, and the new AFR line takes it to the next level with its advanced safety features. Notably, it includes a built-in fire safety shut-off fuse that activates if the attic temperature exceeds 182ºF. This intelligent system ensures that in the event of a fire, the attic fan automatically shuts off, helping prevent the spread of flames and potentially saving lives and property.e temperature and humidity conditions to help with cooling and ventilation in the summer, help prevent ice damming during winter, and combat condensation buildup in humid climates.
