CLOUDLINE A4, QUIET INLINE FAN WITH SPEED CONTROLLER, 4-INCH

This inline fan system packs the CLOUDLINE’s core innovations and premium build quality together to bring you a value package. Designed to quietly cool grow tents, rooms, and closets, and provide ventilation in various air circulation and exhaust projects. Containing an inline mixed-flow design, the duct fan can maintain airflow even in high static pressure applications. The motor box containing the fan’s impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. Complete kit includes one inline fan unit, one speed controller, UIS to 4-pin Molex dongle, installation manual, and all necessary mounting hardware. This product is a part of the UIS™ platform of grow devices and smart controllers, designed to integrate with each other to achieve your ideal environment.


FEATURES

  • Designed to quietly ventilate grow tents, exhaust odors, transfer heating/cooling to rooms, and cool AV closets.

  • Features the same build quality and innovations as the CLOUDLINE Series delivered in a value package.

  • Includes a wired 10-speed fan controller; also compatible with all CLOUDLINE Series smart controllers.

  • Mixed flow design combined with an EC-powered motor for a truly quiet and energy efficient performance.

  • Duct Size: 4” | Dimensions: 6.9 x 11.9 x 7.4 in. | Airflow: 165 CFM | Noise: 29 dBA | Bearings: Dual Ball

 

PRECISE SPEED CONTROLLER

The speed controller enables you to set the duct fan’s speed to optimal noise and airflow levels for various environments. This inline fan is equipped with the CLOUDLINE Series’ same EC-motor that is precisely controlled using PWM (Pulse Width Modulation), which enables it to run smoothly at extremely low RPM speeds without generating motor noise. Ten speed options are available with power switch and backup memory. This model can be connected to the following smart controllers to share the same programming and power source as other EC-motor CLOUDLINE fans:

  • B-Series Temperature Controller

  • T-Series Temperature and Humidity Controller

  • CONTROLLER 69

  • CONTROLLER 67


QUIET AND ENERGY-EFFICIENT DESIGN

The inline fan features 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. In addition, the inline fan is crafted with a plastic mounting base to diminish noise as a result of fan vibration. The unit is IP44 rated to be highly resistant to dust and liquids and performs well even in harsh environments.


APPLICATIONS

This quiet inline fan system is most found in hydroponic grow tents and rooms to provide cooling and ventilation for plants. Its low noise and advanced control features make it fit for bathroom and attic settings, as well as cooling AV equipment rooms, closets, racks, and cabinets.

Flexibility and clean desk space!!!
Bought three of these for my home office. Two for Synology NAS drives and one for a Mac Studio. The size ranges make this the perfect product to get everything off my desk. A little difficult to install with the desk upright so I suggest turning it on its side or over completely. In my case, I have these in sit stand desks which is great.

Decent bracket, Non-beveled screw holes cause complications
The screws that secure the mount to the underside of the desk stick out enough to cause the inner dimensions to change. I had to use the next hole down to increase the size of the bracket to accommodate my device, resulting in a less secure mount than desired. If the holes were beveled so that the screws fit more flush with the mount I'd be able to give it 5 stars. But the inner dimensions are not entirely as advertised due to the screws. Quality is up to standard otherwise, installation is relatively straightforward, price point is fine for a bracket of this size.

Great mount!
Great under desk NAS mount. Adjustable and sturdy, easy to install. Worked well for my Qnap TR-004 four slot DAS. I used 5/64 drill bit for the holes. Since my desk has a rear lip I reused rear stopper bit as a headphone hanger. I bend it slightly to a hook shape.
