AC Infinity CLOUDLINE S10, Quiet 10” Inline Duct Fan with Speed Controller, EC Motor - Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics

Strong but noisier than I expected.

Silent motor, high cfm, good suction and pressure. Fan comes with 2 duct clamps, zip ties, velcro wire ties, lag bolts, sheet rock mounts for motor and controller, and a couple other goodies. I have a lot of Hydrofarm inline fans, 4in and 8in that i use For my kitchen, bathroom and shop exhaust fans. They are very good and i have yet to have 1 die on me. The AC infinity won me over today. Its pressure and suction are just as good or better than a same size hydrofarm, what i love is NO MOTOR NOISE. I dont hear the motor at any speed, just the fan and the air being moved. I have the 10in fan and the 10in filter box installed under my bed as an air filter. On the lowest setting i cant hear the fan under the bed, i do hear the air intake but i can easily box that in and make it silent.

I was using this to replace a 16” surface mounted fan on a specialty waste oil heater. The original fan was very loud for the workspace, so I built a plenum and ductwork and relocated the inlet side to another room with this fan being the source. I was hoping for quieter operation and better airflow for a given wattage, and in that it was a success. I measured the wattage of this 10” fan on all of its ten speeds: 1 6W 2 11W 3 22W 4 36W 5 53W 6 75W 7 102w 8 148w 9 192W 10 249W

Love this fan. If noise is an issue, purchase a larger version, for instance if you don’t want it to sound as if a 787 is taking off inside your closet size up. I.e. if you need an 8 inch fan, buy a10 inch fan ( my personal favorite } and run it at a slower speed. In my opinion a push ,pull setup is best. Clean air in, clean air out. Balancing 2 fans can be tricky. So watch a video so you do not over pressure your room , stink gets out, or starve your exhaust fan. I am heavily invested in AC infinite fans and have several different models and I am happy with them all. Continuous run is not an issue, as I have had 2 ten inch fans and a 6 inch fan running day and night for over 6 months. P.S. if you have a power amp, especially a rack mounted power amp check out there line of home theater fans.

I purchased this fan intended to boost 5 vent in 5 rooms. My 5 bedrooms are 40-50 feet away from the furnace and those rooms have been 4-5 degrees lower than other rooms in winter times. I have installed the 10" booster fan before the duct splits to the five rooms and I have first set the booster fan to its Maximum @ 266W. My furthest room's temperature is raised from normally 64C to my house's set temperature of 68C. I am a little skeptically before this purchase as I am not sure how this experiment will turn out but now I agree that this unit is worth the price and is a quality product. I tuned down the fan level by 1 level @ 196W to reduce power and the vent seems to be fine, I also installed an AC relay so that when the furnace's fan turns on, the booster fan will also be on. I have also removed the Duct in-line fan I previously installed that turns out to be too weak and not helping. There are 8 levels for this fan, and here are the power consumptions for each power level from a Kill-A-Watt meter. 1 - 12W 2 - 16W 3 - 29W 4 - 49W 5 - 81W 6 - 127W 7 - 196W 8 - 266W
