## Questions & Answers

**Q: Will this be good for 48"X24"X60"  tent ?**
A: I use in a 4x4 tent works great.

**Q: For the manufacturer: I’d like this ventilation kit in the 4” size, but with the wifi version of the controller. Is that possible?**
A: Yes totally possible. I think its about 160ish with the remote as well. I opted for the speed controller bundle instead of the wifi controller and i regret not going with the better one. So good thinking on your part to go ahead for the better one.

**Q: Is there a warranty available on this it is not showing up when i addit to my cart ?**
A: All of AC infinity products, except consumables, are under a 2 year warranty. You just have to provide the order number, and confirm your address and AC infinity will replace or repair the defective product. Very easy replacement

**Q: Is the filter also inline with a 6" inlet and 6" outlet?**
A: The filter can be utilized either pulling air out, or pushing air in with the inline fan.
