Garvee 20-Inch Shutter Exhaust Fan, High-Speed Smart EC Motor Ventilation Fan with Intelligent Control, 120V/60Hz, Automatic Self-Closing Shutters for Shed, Garage, Greenhouse & Warehouse - Black
20‑Inch Intelligent EC Industrial Exhaust Fan
Master your commercial facility air metrics with high-efficiency climate automation. Powered by a heavy-duty EC motor to secure a massive 4000 CFM storm-grade air volume displacement flawlessly.
Intelligent Control System
Features an interactive smart control panel that allows for multi-speed adjustments, climate monitoring, and timer automations.
Powerful 4000 CFM Flow
Driven by an advanced EC motor to deliver a heavy-duty 4000 CFM airflow at a rated speed of 1450 R/min for complete air turnover.
Automatic Shutters
Designed with self-acting physical shutters that open automatically when powered on and close tightly when off to block rain and pests.
Automated Climate Tracking Matrix
Take absolute, real-time command over your facility environment. The integrated wall-mountable smart control station features dual built-in sensors for precise, continuous temperature and humidity level monitoring. Effortlessly cycle through multi-speed motor calibrations or lock in custom timer schedules to automate ventilation during heavy-load operational hours.
High‑Efficiency Variable EC Motor
Unlock exceptional commercial ventilation capacity while optimizing power grid consumption. Powered by an elite, next-generation brushless EC motor, this 20-inch industrial exhaust fan generates a relentless, stable vertical airflow of 4000 CFM. Rated at a swift 1450 R/min speed, it flushes out stagnant heat waves, damp moisture, and fumes with maximum efficiency.
Automatic Gravity Weather Shutter
Defend your interior building assets against external weather elements effortlessly. The precision-balanced lightweight shutters are engineered with a responsive air-link linkage mechanism that forces them wide open instantly upon fan activation. The moment electricity cuts off, gravity pulls them completely flat to establish a tight seal that blocks rain, debris, and pests.
Robust Carbon Steel Armor Frame
Built to endure relentless operational demands across both indoor and outdoor environments. The structural frame shell is stamped entirely from thickened carbon steel to deliver immense rigidity and fully eliminate body vibrations under full speed. Enveloped in a premium, scratch-resistant black powder coating that shrugs off rust, moisture rot, and UV corrosion.
Precision 20-Inch Architectural Profile
Simplify wall mount placement with a clean, low-profile architectural structure. The industrial-standard 20-inch configuration allows for hassle-free installation between structural framing studs without requiring extensive masonry adjustments. Provides an absolute flush seating layout that fits clean into wood, concrete, or brick walls.
Multi-Scene Heavy Circulation Flagship
The definitive structural solution for high-volume air circulation across a massive variety of challenging setups. Installs beautifully into commercial distribution warehouses, active manufacturing factories, high-humidity agricultural greenhouses, auto repair garages, backyard workspaces, workshops, and barns.

Pro Ventilation Operations & Automated Maintenance Guidelines
Optimal Mounting Orientation: For maximum 4000 CFM air displacement efficiency, secure the 20-inch carbon steel chassis into your header wall perfectly level. Ensure the automatic louver shutters pivot outward away from the room, allowing gravity to seal them completely flat when electricity cuts out.
Sensor Probe Management: Position the smart controller's dedicated climate tracking probe at mid-height inside your greenhouse or factory, away from direct thermal exhaust drafts or water irrigation streams, ensuring precise, uncorrupted ambient humidity and temperature trigger reads.
End-of-Season Maintenance: The brushless EC motor core is completely sealed for long-term maintenance-free life. Periodically check the shutter links to remove external dust or leaf accumulation that could block opening fluidity, keeping your weather protection line working like new year after year.
