Product Description

A shutter exhaust fan designed to exchange air in large spaces, improving ventilation in workspaces like warehouses, greenhouses, garages, and workshops. By installing this exhaust fan, you can refresh your workspace and regulate heat, moisture, and odor levels to improve comfort. It is run by a PWM-controlled EC motor that is energy-efficient while enabling precise fan speed control to generate your ideal ventilation level. This control is powered by a speed controller that enables up to 10 fan speed levels. Its heavy-duty build features aluminum fan blades, steel wire guards, and lightweight steel shutters. This product is a part of the UIS™ platform of grow devices and smart controllers, designed to integrate with each other to achieve your ideal environment.

Precision Fan Speed Control

This shutter fan includes a speed controller that enables you to set its speed to optimize noise and airflow levels in various environments. The fan speed control is supported by its EC motor that is precisely controlled using PWM (Pulse Width Modulation), which enables it to run smoothly at extremely low RPM speeds without generating motor noise. Ten-speed options are available with a power switch and backup memory.

Heavy-Duty Performance

Features steel shutters that are weather and corrosion-resistant, automatically closing when not in use to prevent dust, debris, and moisture from entering your space. The blades and impeller are constructed of lightweight aluminum, weight-balanced to reduce vibrations. Utilizing an innovative EC motor that is controlled electronically using PWM (Pulse Width Modulation), the fans can maximize airflow while reducing noise and power consumption. The fully enclosed motor is also permanently lubricated and houses dual-ball bearings that are rated at 67,000 hours. The unit is IP-44 rated to be highly resistant to dust and liquids and performs well even in harsh environments.
