10 Best Thru Wall Exhaust Fans 2025 in the United States

The Restaurant Canopy Hood Grease Rated Exhaust Fan (DU12HFA) is well-suited for restaurant and general ventilation applications, offering an airflow capacity between 100-500 CFM. This range allows for effective ventilation in various kitchen settings, helping to maintain a clean and grease-free environment. The fan is equipped with a high-speed direct drive centrifugal upblast system and features a variable speed control, enabling users to adjust the fan's performance to their specific needs. Additionally, the inclusion of a disconnect switch and 10-1/2" wheel ensures ease of operation and maintenance. The construction is robust, with a heavy gauge aluminum housing, which contributes to its durability.

It also includes a backward inclined, non-overloading wheel and vibration isolators for stable and quiet operation. Given its application, it is likely to be on the noisier side compared to residential fans. The exhaust fan comes with essential built-in features like a restaurant duty grease cup, down spout, and a hinge kit for roof curbs, which are particularly beneficial for grease-laden environments. It is UL705, UL762, and ULC-S645 certified, ensuring it meets safety standards. Its energy efficiency might not be its top strength given the 0.180 HP motor and 134-watt power consumption, but it does provide reliable performance for heavy-duty use.

The installation process may require professional assistance due to its weight (62 pounds) and specific requirements. Manufactured in the USA, it comes with a one-year warranty and technical support. The fan appears to be a dependable choice for restaurant ventilation but may not be the best fit for quieter, energy-efficient needs or straightforward self-installation.

The iLiving 36-inch Wall Mounted Shutter Exhaust Fan is designed to provide efficient ventilation for spaces like attics, garages, sheds, and other areas in your home. It boasts a high airflow capacity of 6128 CFM, making it suitable for larger areas up to 9000 square feet. This high capacity ensures effective removal of excess heat and moisture, which can help reduce cooling costs and improve comfort in the living space.

Additionally, the 36-inch fan is constructed with durable aluminum blades and weather-resistant shutters, enhancing its longevity and ability to withstand tough conditions such as moisture and heat. The motor is also thermally protected and permanently lubricated, minimizing maintenance needs. However, it is worth noting that the fan operates at a single speed and does not offer variable speed control, which might be a limitation for those who need adjustable airflow. Despite its powerful performance, some users might find the noise level to be on the higher side, which could be a consideration if used in more noise-sensitive areas.

Installation is straightforward, but due to its weight (65.3 pounds) and large size, it may require two people for proper setup. The energy efficiency is described as low, which means it could contribute to higher electricity bills if used extensively. Additional built-in features like automatic shutters enhance convenience by closing to prevent backdrafts when the fan is not in use. The iLiving ILG8SF36S is a robust and high-capacity exhaust fan ideal for large spaces needing consistent and strong ventilation, though users should consider its noise level and energy consumption.

The KEN BROWN 20 Inch Shutter Exhaust Fan is designed to provide strong ventilation, delivering a high airflow capacity of 3500 CFM, which is excellent for quickly removing heat, moisture, and odors from spaces like garages, workshops, and greenhouses. It operates at 1309 RPM, powered by 120 volts and 130 watts, making it energy efficient for continuous use. The fan features corrosion-resistant aluminum blades and shutters, enhancing durability in moist or hot environments, which is a big plus if you need a fan that lasts.

Installation is simple since it comes wall-mounted with a 1.65-meter power cord—just plug it in without complicated wiring. Automatic gravity shutters open and close with the fan operation, helping to keep out dust and pests when the fan is off. On the downside, the noise level is around 60 dB, which is noticeable and might be a bit loud for quiet residential areas but typical for industrial fans. It has a single speed setting, which means less control over airflow adjustment compared to models with multiple speeds.

The fan weighs about 20 pounds and has a modern brown metallic finish that suits many indoor settings. It’s indoor-rated and recommended for exhaust and ventilation tasks, best suited for larger spaces where strong airflow is a priority rather than very quiet operation. This fan represents a solid choice if you want a robust, easy-to-install unit that handles tough ventilation needs without fuss.
