High-Performance Shutter Exhaust Fan with Speed Control

This heavy-duty shutter exhaust fan delivers powerful ventilation for large indoor areas such as greenhouses, garages, workshops, and warehouses. Designed to replace stale air with fresh air, it helps manage heat, humidity, and odors to improve air quality and comfort.

The built-in EC motor with PWM (Pulse Width Modulation) control provides energy efficiency and quiet performance. Use the included 10-speed controller to fine-tune airflow based on your environment. The motor operates smoothly even at low RPMs, ensuring silent and precise control.

Constructed with aluminum fan blades, steel shutters, and wire guards, this exhaust fan is built to withstand tough conditions. Its IP-44 rated housing protects against dust and moisture, making it suitable for harsh environments. Permanent lubrication and dual ball bearings ensure long-lasting performance.

This fan is part of the UIS™ ecosystem and integrates seamlessly with other smart grow devices and controllers for complete climate management.
