AC Infinity CLOUDLINE A8, Quiet 8" Inline Duct Fan with Speed Controller. | EC Motor - Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics

I purchased this blower for use with an 8” independent insulated duct system that I installed in my attic to redistribute excess heat from the room my new wood burning stove is located in, to the rest of the house. The blower is very quiet even at full speed can move large a large volume of air. The variable speed control is nice although I do believe it would have been nice that the corded speed control’s form factor matched a US a rectangular switch plate/electrical outlet face plate dimension with and/or a faceplate mounting kit for a clean, permanent installation as the faceplate of the control is just a bit too big. Very happy with the unit so far

Purchased to push more air from a central furnace to a room that is far away (and only had a single vent in the room). Works as expected! The room is sufficiently cool in the summer and warm in the winter. The installation package comes with every possible option needed to install the inline duct fan. The unit disassembles so that the support housing can be installed without the motor/blower. Once installed, the motor / fan drop simply drop in and are secured with screws. Easy. The unit comes with a a 10 speed controller which is a must. I found that setting 2 is sufficient to push air to a far away room. At a speed of 3 there is a slight noticeable sound at the far end vent. Keeping in mind the house has a 1960's HVAC system that is essentially a series of is a long metal tubes, so without dampening additional noise probably to be expected. Even at level 10, it's not deafening. Setting 2 (out of 10) moves enough air to compensate what I had before. The unit is very quiet and does the job.

A quality product! Really really quiet, and well constructed . Blower shipped with lots of mounting and fastening materials - More than I would have expected! Clearly a good company, and if I need another blower, I will go to AC Infinity.

very high quality - powerful fan system

Initial thoughts, I give this 5 stars, but, the speed controller has these 10 small obnoxiously bright LED lights, so I'm whacking one star. They're the white/blue type. Wow, they're like miniature lasers piercing your eyes. They should have gone with red, not the white/blue. The fan is made of plastic, but it's durable. Blades are sturdy. No flimsy materials used. The fan is pretty quiet. Speeds 6+ are pretty noisy, but then again, when you're shoving 730 cubic feet of air into an 8" tube, it's going to make some noise. I find that acceptable. Lots of air flow, which is what we wanted. Once we start using this more, I may be back to update if needed.

Ive had this for almost 8 months and it works great

I'm used to ordering duct fans that make a lot of noise but don't really move much air. This is an exception, it moves a massive amount of air even on it's lowest setting. At full power it's enough to blow papers off a desk from 20 ft away with a noise level to match. I'm likely never going to need to run it over 40%. My only complaint is that the speed controller only has one button and it runs from low to high so you have to run though the entire speed range to slow it down.

I own a beauty salon and we have added a nail tech and we needed to vent that work room to remove the odors. Didn't want to cut any holes in the wall so we just hooked a duct to the furnace return grate and used this fan to pull the odors out and vented it outside. It works great and is probably more than we needed but it serves us perfectly. It an alternate use of this product but if you need to remove smells and odors this is a great way to do it. It was easy to install , it's fairly quiet, and it really Sucks!!!

Leistungsstarker Ventilator. Für den Umbau meines Bitcoin Miners sehr gut geeignet
