Product Description
This smart inline duct fan is designed to quietly ventilate grow tents, redirect heating and cooling, supply fresh air and cool AV cabinets.
Thanks to the mixed-flow design, airflow remains constant even at high static pressure, and the PWM-controlled EC motor ensures quiet, efficient operation. The motor housing can be removed for cleaning. As part of the UIS™ platform, the fan integrates seamlessly into smart grow setups.

Mixed-flow design
The mixed-flow design with stator blades and two hydrodynamic air channels ensures high airflow even when air movement is restricted.
Quiet and energy-efficient
The precise, PWM-controlled EC motor runs considerably quieter and uses less power than conventional AC (alternating current) motors. PWM technology enables smooth, quiet operation even at very low speeds.
Precise Speed Controller
The included speed controller adjusts the fan speed precisely in ten levels to match noise and airflow requirements. A memory function automatically restores the last setting after a power failure.
Durable and easy to maintain
The dual ball bearings are rated for around 67,000 hours and allow mounting in any position. The IP-44 rating protects against splashing water and solid objects. The motor housing can be removed for cleaning.

Applications
Ideal for grow tents and grow rooms, AV cabinets, racks and equipment rooms, as well as bathrooms, attics and many other circulation and exhaust projects.
UIS PLATFORM
Speed controller included – UIS controller optional
The included speed controller covers the basic functions. A UIS controller additionally integrates the fan into the AC Infinity system – with smart programming and app control.
UIS controller sold separately, for example the CONTROLLER AI+.
