## Description

desertcart.com: AC Infinity CLOUDLINE PRO S12, Quiet 12” Inline Duct Fan | With Speed Controller - EC Motor Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics : Patio, Lawn & Garden

Review: Fantastic deal - Quiet, powerful exhaust fan. Using it for a whole house circulation. The remote can be interfaced with a microcontroller generating a pwm signal, for extremely powerful and customized control.
Review: They move a lot of air and are reliable. - This is my second one of these (12"). Not because the first one broke but because I had an additional project. They are relatively quiet and push a lot of air. One has been running an exhaust for my metal shop for over 3 years and still works flawlessly. The second is running a DIY air cleaning system that I put in my woodshop -- barely hear it in the attic and, again, pushes a ton of air. Recommend.

## Features

- Features a wired 10-speed fan controller; also compatible with all UIS controllers with intelligent programming.

## 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
