💨 16" Shutter Exhaust Fan – 2900 CFM Smart Attic Vent with Variable Speed & Temperature Control
Does your garage turn into an oven in July? Is your greenhouse stifling, or your workshop full of stale air and dust? The 16" Shutter Exhaust Fan is not just another wall fan – it’s a smart ventilation system. With a massive 2900 CFM airflow, it can completely exchange the air in a typical two‑car garage in under 30 seconds. But the real game‑changer is the intelligent controller: set temperature and humidity triggers, and the EC motor automatically adjusts its speed (up to 10 levels) to maintain perfect conditions. No more manual on/off – just set it and forget it.
Built with an all‑metal steel construction (black powder‑coated), this fan resists rust, rain, and damp conditions – ideal for sheds, greenhouses, attics, and even covered outdoor areas. The premium EC motor runs quietly at up to 1400 RPM while consuming only 98 watts, saving energy compared to traditional AC motors. The built‑in timer and alarm give you full control, and the auto‑shutters keep out pests and weather when the fan is off. Whether you need to cool a hot attic, vent humidity from a greenhouse, or remove welding fumes from a shop, this smart exhaust fan delivers professional‑grade performance with hands‑free convenience.

❔ Frequently Asked Questions
Does the fan come with a power cord? Do I need to hardwire it?
This fan includes a standard 120V AC power cord with a plug – just plug into any nearby outlet. No hardwiring required. The smart controller is integrated; you can also wire it to a wall switch if desired, but the included cord works for most users.
How do I program the temperature and speed settings?
The controller has an LCD screen and buttons. You can set a target temperature (e.g., 80°F) and a humidity threshold (e.g., 60%). The fan will start at low speed when the threshold is approached, then ramp up automatically. Up to 10 speed levels. A timer can also be set for manual operation. The manual includes step‑by‑step programming.
How big of an opening do I need to cut?
The outer housing is 20.47" square. The required wall cutout for the louver frame is approximately 16.5" x 16.5". Exact dimensions are in the manual. Use a reciprocating saw or jigsaw for wood siding; for masonry, use a hammer drill with a core bit.
Is this fan suitable for a greenhouse? Will humidity damage the controller?
Yes, it’s designed for greenhouses. The all‑metal construction and EC motor are sealed and resistant to humidity. The controller is splash‑resistant (IPX4 rated typical). For very high humidity (e.g., tropical greenhouses), mount the controller in a dryer location and extend sensor wires – possible with minor modification.
How noisy is this fan at full speed?
At 2900 CFM, sound level is approximately 65–68 dB at 3 feet – similar to a loud conversation or a window AC unit. At lower speeds, it’s much quieter. The EC motor eliminates the hum of traditional AC motors, so noise is mainly airflow.
Can I use this fan as an attic fan? Does it need a separate thermostat?
Absolutely. It’s perfect for attics. The built‑in thermostat and humidistat mean you don’t need any external controller. Mount it in a gable end or roof (with proper flashing), set your desired temperature, and it will run automatically.
Will the shutters close completely when the fan is off? Can rain get in?
Yes, the spring‑loaded aluminum shutters form a tight seal when the fan stops. Rain and snow won't enter under normal conditions. For hurricane‑driven rain, we recommend an external hood, but for most installations, the shutters are sufficient.
💡 Installation tip: For maximum efficiency, mount the fan on a wall opposite your main entry door to create cross‑ventilation. In attics, place it high on a gable end. Use a level and seal around the frame with exterior caulk to prevent air leaks.
🌬️ Take control of your space's climate – add this smart 16" exhaust fan to your cart and enjoy automated, powerful ventilation.
