Technical Specifications

Product Details

Product Description

A smart inline duct fan designed to quietly ventilate hydroponic grow rooms, boost heating/cooling to rooms, circulate fresh air,exhaust projects, and cool AV closets. Featuring an inline mixed-flow design, the duct fan can maintain airflow even in high static pressure applications. Contains an EC-motor with PWM-control for quiet and energy-efficient performance. The motor box containing the fan’s impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. Includes a smart controller with dynamic climate and time-based programming, and can connect to one additional fan. The complete kit includes one duct fan unit, one thermal controller, one corded thermal probe, two duct clamps, an installation manual, and mounting hardware.
Precise Speed Controller
The inline speed controller enables you to set the duct fan’s speed to optimal noise and airflow levels for various environments.Unlike common AC-powered duct fans that suppress voltage to control fan speeds, this duct fan features an EC-motor that is precisely controlled using PWM (Pulse Width Modulation). This technology enables the fan's motor to be able to run smoothly at extremely low RPM speeds without generating motor noises and heat as seen on variable voltage controllers. Eight speed options are available with a power switch, and backup memory.

A Quieter and Smarter Inline Fan

This series contains a cutting-edge Electronically Commutated (EC) motor, controlled using precise electronic pulses and
smart programming. This enables the inline fan to operate considerably quieter and reach low speeds without generating noise or
heat. The EC motor is also twice as energy-efficient and can save up to 40% in energy costs, paying for itself in the long run.

Key Features

Smart Programming

T-series models include a dynamic temperature and humidity controller with timers, cycles, scheduling, and Bluetooth App control.

Mixed-Flow Design

Featuring a mixed flow design, the fans maintain peak performance in high static pressure environments. Ingress-protected against dust and liquids.

Quiet PWM Motor

Each fan uses a quiet, energy-efficient EC motor controlled using Pulse Width Modulation (PWM). Dual ball bearings allow for omnidirectional mounting.
