## Description

AC Infinity CLOUDLINE S12, Quiet 300mm Inline Duct Fan with Speed Controller - Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics, 12-Inch : desertcart.co.uk: DIY & Tools

Review: Added some ductwork in my house two years ago to help distribute the heat from the woodstove. This fan running 24/7, 6-7 months out ofthe year. Well worth the money compared to the units at H/D or Lowe's.
Review: Read: if you have a 12” supply line running it the upstairs of your home and the air conditioner just isn’t pushing the air to the registers, get this!!! Installed one in a 2700 sq ft two story home with the furnace in the basement, there is now measurable air reaching the entire top floor. And the best part is you cannot hear it from outside the utility/mechanical room, even when running at full power.

## Questions & Answers

**Q: hello,i gonna use it in my grow room.
do i really need the carbon filter while using this fan?
if yes,can i use other brands carbon filter with it?**
A: This machine just blows air in or out.  The carbon filter get rid of smell. Two different things.  Yes, you can use a different filter mix and match equipment.

**Q: Is there no option to buy 2 fans and 1 controller?**
A: No there is no option for buying 2 fans and 1 controller. If you do buy 2 fans I would get 2 s models and buy the controller separately. Saves a little bit of money and get the same results!

**Q: I have read the reviews discussing the sizing issues with the inlet/outlet sizes being more 12.25 instead of 12.  Has this issue been corrected?**
A: If your trying to put that 12 inch flexible ducting you basically cant and just have to get aluminum tape. Its not that big of an issue though. With the tape it stays put.

**Q: Can this fan be used to exhaust kitchen hoods (e.g. inline connected to a hood liner)?**
A: I would not use such an expensive fan for a kitchen exhaust hood. The condensation and grease steam alone would gum it up and ruin it. They sell hood exhaust fans
