Product Description
This smart inline duct fan is designed to quietly and efficiently ventilate grow tents and grow rooms, boost heating and cooling, circulate fresh air, remove odors 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, energy-efficient operation with minimal heat. The motor housing with rotor and blades is removable, making cleaning and maintenance easier. A smart controller with sensor probe is included. 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.
Smart controller included
The included CONTROLLER 69 PRO offers smart programming with temperature, humidity and VPD triggers (VPD: vapor pressure deficit) and dynamic fan speeds that adjust automatically to climate changes. A minimum speed runs continuously and only increases when needed; timer, cycle and schedule modes complete the control.
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.
SMART CONTROLLER
Smart controller included
The included CONTROLLER 69 PRO regulates the fan automatically according to temperature, humidity and VPD. It connects via WiFi to the AC Infinity app.
