CLOUDLINE T4, Quiet Inline Mixed-Flow Duct Fan System, 4 Inch
- Designed to quietly ventilate grow tents, transfer heating/cooling to rooms, circulate fresh air, and cool AV closets.
- Intelligent controller with thermostat programming, speed control, alarm warnings, and backup memory.
- Mixed flow design combined with a PWM-controlled DC-motor for a truly quiet and energy efficient performance.
- Kit also includes thermal probe, AC power adapter, two duct clamps, and all necessary mounting hardware.
- Duct Size: 4” | Dimensions: 6.9 x 11.9 x 7.4 in. | Airflow: 152 CFM | Noise: 28 dBA | Bearings: Dual Ball
The quiet duct fan system is designed to quietly cool AV equipment rooms and closets, and to ventilate various air circulation and exhaust projects. Featuring an inline mixed-flow design, the duct fan can maintain airflow even in high static pressure applications. Contains a DC-motor with PWM-control for a 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 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 to power the unit through a standard outlet.
The controller features an on-board processor with active temperature monitoring that will automatically adjust fan speeds to respond to varying temperatures. For non-cooling ventilation applications, the controller can provide a readout of the duct fan’s speed and status; and the programming can be set to run continuously at customizable speeds with easy shut-off and power on-off memory. Additional features includes an alarm system, eco-mode, display lock or off while programs are running, three back-light settings and two buffer options. Features a detachable 8-foot precision thermal probe that is water resistant.
QUIET AND ENERGY EFFICIENT DESIGN
Unlike common duct fans that uses an AC-motor which are loud and unmanageable, this duct fan features a 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.
This quiet duct fan system is popular in a variety of applications including cooling AV equipment rooms, closets, racks, and cabinets. Due to its low noise and advanced control features, it’s also used in various air circulation and ventilation projects including hydroponic grow rooms and tents, exhausting bathrooms and attics, and other installations.
