AC Infinity CLOUDLINE PRO T4, Quiet 4” Inline Duct Fan with Temperature Humidity VPD Controller, WiFi Integrated App Control - Ventilation Exhaust Fan for Heating Cooling, Grow Tents, Hydroponics

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 DC-motor with PWM-control for a quiet and energy efficient performance. Includes an intelligent controller that features advanced programming and functions. Complete kit includes one duct fan unit, one thermal controller, one corded thermal probe, two duct clamps, installation manual, all necessary mounting hardware, and a corded AC plug adapter.

The controller can be programmed to adjust fan speeds to respond to varying high and low temperatures, and humidity. For ventilation applications, the controller can be set to run continuously, or triggered to run at customizable speeds when given power, due to its backup memory capability. Additional features includes a countdown timer, alarm system, and eco-mode. Includes detachable 12-foot precision water-resistant probe.

Unlike common duct fans that uses an AC-motor which are loud and unmanageable, this duct fan features an DC-motor that is controlled using PWM (Pulse Width Modulation). This technology enables motors to be able to run smoothly at extremely low RPM speeds without generating additional heat or noise. In addition, the duct fan uses a mixed flow design using a stator blade and dual hydrodynamic wind circles. This gives it a high static pressure rating, enabling it to deliver airflow even in applications where air movement is being restricted. The motor houses dual ball bearings rated at 67,000 hours which allows the duct fan unit to be mounted in any direction. The unit is IP44 rated to be highly resistant to dust and liquids, and performs well even in harsh environments.
