Description

Designed to quietly ventilate grow tents, transfer heating and cooling between rooms, circulate fresh air, and cool AV cabinets. It features a 10-speed wired fan controller and is fully compatible with all UIS controllers with smart programming.

The EC motor with PWM control ensures quiet, energy-efficient operation with minimal heat and noise. The mixed-flow design with stator blade and hydrodynamic rings enables strong airflow delivery even in high-resistance applications.

The motor housing containing the impeller and fan blades can be removed from the mounting frame for easy cleaning and maintenance. Includes an intelligent controller with dynamic climate adjustments and timer programming, compatible with multiple UIS devices. Part of the UIS™ platform for fully integrated grow environment control.

Precision Speed Controller

The 10-level speed controller allows fine airflow and noise optimization. The advanced EC motor managed through PWM enables smooth operation at extremely low RPM without motor noise. A backup memory retains the last speed setting after power interruptions.

Quiet and Energy-Efficient Design

The mixed-flow structure with stator blade and dual hydrodynamic rings delivers airflow even where ventilation is restricted. Dual ball bearings provide a 67,000-hour lifespan and allow installation in any orientation. Rated IP44 for high resistance to dust and moisture.

Applications

Ideal for cooling AV equipment rooms, cabinets, racks, and for household ventilation such as bathrooms, attics, grow rooms, and grow tents. Its silent operation and advanced controls make it suitable for various air circulation and extraction setups.
