AC Infinity CLOUDLINE Inline Fans With Speed Controller

The CLOUDLINE inline duct fan system is designed to quietly cool AV equipment rooms and closets, and to ventilate various air circulation and exhaust projects. Features an inline speed controller utilizing PWM-technology. Containing an inline mixed-flow design, the 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 duct fan unit, one inline speed controller, installation manual, mounting hardware, and a corded AC plug adapter to power the unit through a standard outlet.

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 suppresses voltage to control fan speeds, this duct fan features a DC-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 power switch, and backup memory.

#1 Q:   I need a two quiet fans to provide fresh air and exhaust air from an 11x15 sound room. What setup do you recommend? I really only need very low air flow since the sound room is in a basement and temperature will not vary (just need fresh air). I noticed that these fans have an optional duct fan silencer. What is that and how effective is it to reduce sound? Would I need to build a baffle box or are the fans quiet enough?
A:   Quiet enough is very subjective. The fan choice for low sound is good with these fans. They are very good and speed controllable. Place the fans where any radiated noise from the fan casing does not interfere or build a lined box around the fan. Definitely use a silencer. Use the Fantech LD series as they have actual sound reduction data in the specs: https://www.hvacquick.com/products/residential/Kitchen-Exhaust/Silencers/Fantech-Silencers

#3 Q:   Suitable for kitchen hood fan?
A:   It could be used in that application, although the hard wired controller will make for a complicated install as you must use the one that comes with it.

#4 Q:   Would you recommend the Cloudline or the FG Series for Fireplace blower?
A:   They have the same max airstream rating (140 F). You would have to shield them from any radiant heat. Both are very good products so I would choose on price and desired airflow. The Cloudline fans are much more controllable (come with speed controller).

#5 Q:   What is the max air temperature this is rated for?
A:   They specify 14 to 230 F as the ambient operating temp range. The max sustained airstream temp is 140 F, same as most inline fans.
