AC InfinityCLOUDLINE S8, Quiet 8” Inline Duct Fan with Speed Controller - Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics

Bought it for a DIY Air Purifier, and it's extremely powerful on max settings. Looks good too, it's well made. I'd order from them again when I aim to get a humidifier.

I read the reviews before buying, and i've got to agree, this fan is very powerful on full power, even on the low speed, there is very good air flow. its very quiet on the low speeds, came fitted with a UK plug.. very happy with this purchase.

This is crazy powerful, it will literally take off if not held down. It has single handedly resolved my heat problem on my rig. Absolute must buy for miners. Quality is excellent, noise is acceptable. A+

Did not come with a remote as said in ad and is the speed is set to max so can’t actually use till I get a remote to control it but over all a great product

thumbs up

I was planning to use the unit to boost air flow across a HEPA filter (got excited about the "booster" part in the title). I expected more airflow at the output than I was getting (air flow reduced about 3-fold at max setting). I will keep the unit b.c. it is affordable, and it has speed control; will use it to test 12" panel filters. Will need to get a centrifugal unit to use as a booster in an HVAC duct.

These are a serious bit of kit for the money. Gave 3 star for noise as they are noisey but doubt you will find one out there that isn't. It sounds like a jet engine about to take off before you even get to full power. I've brought the ac infinity silencer to reduce noise and its still to loud if want to take it above the 3rd power setting. But for me I find setting 3 more than enough for a 2mx2m set up. Would definitely buy again and would definitely recommend. Would also recommend buying silencer aswel though

Amazing
