Description
20" Heavy-Duty Shutter Exhaust Fan & 3500 CFM
Reclaim pristine air quality in your demanding spaces. Powered by a high-efficiency 150W industrial motor, this wall-mounted ventilation unit unleashes a massive 3500 CFM airflow to rapidly refresh hot, stagnant environments.
💨 High Airflow Efficiency
Delivers a robust 3500 CFM output at 1500 RPM. Rapidly exchanges airborne particles, humidity, and odors—making it the ideal ventilation choice for garages, attics, and greenhouses.
🛡️ Automatic Weatherproof Barrier
Precision aluminum shutters open and close dynamically with the fan's operation, forming a 100% lock against backdrafts, driving rain, seasonal dust, and insects.
⚡ 5-Minute Rapid DIY Setup
Skip the stress of complex hardwiring. Arrives fully loaded with a pre-installed 4.9 ft grounded power cord. Simply mount into your wall framing setup, plug in, and dominate heat build-up.
🥇 Patented Automated Weather Shielding Mechanics
Protect your interior from harsh seasonal elements without manual adjustments. The lightweight, precision-balanced aluminum shutters respond instantly to internal airflow pressure. When the fan powers down, the blades gravity-close tightly to eliminate cold air intrusion or moisture penetration in any climate condition.
🔌 Zero-Wiring Plug & Play Convenience
Avoid the high costs of commercial electrical contractors. Featuring an integrated, heavy-duty 4.9-foot pre-wired power cord, this industrial wall fan plugs straight into standard grounded residential receptacles. Perfect for fast, straightforward DIY retrofits across home sheds, workshops, or hobby greenhouses.
🌀 Advanced Low-Noise Aero-Acoustic Engineering
High-volume air exchange doesn't have to mean deafening workshop roar. Optimized blade geometry combined with a premium fully enclosed motor layout keeps operating acoustics at a calm ≤60 dB threshold. Enjoy constant, stable ventilation comfort without disrupting quiet residential neighborhoods or indoor focus zones.
💪 Structural Armor Built for High-Humidity Abuse
Engineered to outlast standard ventilation equipment. The ultra-light balanced aluminum blades repel aggressive corrosion while minimizing motor shaft drag. Outfitted with an OSHA-compliant, safety-coated high-tensile steel protective guard mesh, it effortlessly blocks accidental debris contact in intense garage or workshop environments.

Pro Exhaust Fan Installation & Maintenance Tips
To maximize ventilation draft cross-physics, always install your 20-inch exhaust fan on a wall directly opposite your garage or greenhouse's primary intake air louvers or windows. Ensure the perimeter square frame is packed with professional weather-stripping foam during installation to lock out vibrations. Periodically clear away external tree branch clutter or heavy pollen dust build-up from the aluminum shutter hinge tracking to preserve a lifetime of crisp automatic operation.
