Key Features & Benefits1. High-Performance 3500 CFM Airflow
Engineered to move substantial air volumes efficiently, this fan rapidly exhausts hot air, dust, fumes, and humidity from large spaces. With a powerful 150W motor operating at 1500 RPM, it provides industrial-level ventilation that significantly reduces indoor temperatures and improves overall air quality, creating a safer and more comfortable working environment.2. Automatic Self-Closing Shutter System
The integrated aluminum shutters open automatically when the fan is operational and close securely when the fan turns off. This intelligent design prevents backdrafts, blocks cold air infiltration during winter months, and deters insects and pests from entering. The automatic operation also protects the internal motor from dust and moisture when idle, extending the equipment's lifespan.3. Durable All-Aluminum Construction
Built for longevity in challenging conditions, the fan features corrosion-resistant aluminum blades and shutters that withstand high humidity, temperature fluctuations, and exposure to industrial atmospheres. Unlike steel components, the aluminum construction inherently resists rust, making it ideal for moisture-prone environments like workshops, greenhouses, and agricultural buildings.4. Simplified Installation & Operation
Designed for user-friendly setup, the fan arrives fully assembled. Installation requires only wall mounting of the pre-assembled frame and connection to a standard AC power source (power cord sold separately). No complex assembly or technical expertise is needed, allowing for immediate operation to address ventilation needs.5. Versatile Multi-Environment Application
This unit is engineered to perform reliably across diverse settings:

• Industrial: Effectively removes welding smoke, sawdust, and chemical fumes
• Agricultural: Regulates temperature and humidity in greenhouses and livestock barns
