For homes up to 6000 sq. ft. the AirScape 4.5 delivers the high airflow required for larger homes while maintaining the low-noise profile that AirScape is famous for. In fact, this is both our most powerful AND our quietest unit. How is this possible? An exceptionally robust industrial-grade fan, isolated through a noise-deadening ducted design puts the 4.5 in a class all by itself. It's more expensive to build, and requires a little more energy to run, but the performance -- in terms of both airflow and noise -- is truly exceptional. Plus, the 4.5 is low-speed-adjustable, straight-forward to install and comes with a hi-flow grill that minimizes noise and looks as unobtrusive as it sounds.
Ultra-high power, still low noise
While all AirScape fans deliver high power and low noise, the 4.5 delivers massive airflow at surprisingly low noise levels. The ducted design and smooth and powerful 20-inch motorized impeller fan work together to achieve excellent performance/noise ratio. The amount of air this unit moves is impressive, and the noise level at which it does this is even more impressive
Industrial build quality
Exceptional engineering and build quality is a foundational feature of all AirScape units, the 4.5 is no exception, with heavy industrial-grade components that are rare in the consumer market. The shipping weight of this unit is over 100 lbs; the fan alone, with its cast-aluminum motorized impeller, weighs nearly 50 lbs. Every aspect of this unit is built to a rigorous specification suitable to demanding industrial applications.
Two-speed operation
On high speed, you get a whopping 4673 CFM to cool your house down fast without sounding like a jet engine. Set to low, the 4.5 runs virtually silent -- all you'll hear is air whooshing quietly through the cube core grill. The unit is controlled via a wall-mounted switch (included) or optional wireless remote.
Adjustable low-speed setting
Also, the low-speed setting is user-adjustable, so you can tweak it according to your tastes and installation requirements to achieve maximum low-speed flow rates while maintaining near-silent noise levels.
Automatic insulating damper
A key drawback with traditional whole house fans was air leakage between the attic and living spaces. This could result in dirty attic air entering your home, and, in cold climates, warm, and moist indoor air entering the attic and causing water damage through condensation. Properly installed, the AirScape 4.5 takes care of this problem with AirScape's proprietary automatic damper system. When the fan is off, your attic is sealed tight. So attic air NEVER leaks into your living space, and warm air never condenses in your attic.
Premium Cube Core grill
The AirScape 4.5 comes with a premium high-flow grill that minimizes air movement noise through the grill. These high-performance grills look great too, so your system looks as unobtrusive as it sounds.
Easy installation
The AirScape 4.5 damper unit mounts between standard joists, either 16-inch or 24-inch centers using pre-drilled tabs. The fan is hung from the rafters with supplied hardware. Equipped with a standard plug and an available remote control, the unit can be installed with plug and play simplicity. See our ducted installation page for complete details.
Maintenance-free operation
The AirScape 4.5 employs an industrial fan unit which is sealed and never requires lubrication. The only other moving parts are the twin heavy-duty door actuators which are tested to 45,000 cycles and are also maintenance-free. All mechanical and electrical parts are accessible and can be serviced or replaced without removing the entire unit.
3-year warranty backed by professional support
Not only are the units guaranteed for 3 years, but they're backed by our professional technical support. If you have a problem with your unit -- or just a question -- you'll get prompt, knowledgeable responses from real engineers. Guaranteed.
