Review: Perfect laser cutter external extractor fan - Very powerful extractor. Used to externally duct a xTool P2S laser cutter. More powerful than the standard internal extractor and much quieter. Good upgrade.
Review: Absolute must have for cooling your premises down - I purchased this cloud line S6 to try to cool my bedroom down. I was so impressed with it and the way it performs I bought another one to put in my bathroom for air circulation. My room temperature has gone down 50% and I’m only using half of the power of the S6 unit. As you can see by the image, I have a prospects window which is hard to see that the unit pushes air through.

## Questions & Answers

**Q: What is the max temp of use for this fan? i see you said 240f, but all other manufacturers with plastic impellers say max temp 140f. are you certain?**
A: Always stay a minimum of 25% below specified temp. At minimum they can warp and and motor performance would be affected

**Q: If powered from a switched outlet, will it remember the last speed setting or does that require constant power?**
A: Morning RS, the S4 will not remember your fan speed. It’s a manual setting only. I also have a T4 with a smart controller and it does remember and can be set to auto for heat and humidity. The T4 is for auto exhaust and S4 is intake. If it is your only fan go with the T4. Also, if you have more than 200sf to ventilate go directly to the T6. The are very quiet which is important as my room is under a bedroom. Hope this helps.

**Q: How well does this work with a carbon filter?**
A: I have a 350 Cfm Coco/Carbon Fiber filter that I place on the Exit side of my application. I have tested the filter on both the intake and the exit. I found these units Push much better than they Pull. I do have to increase the power by 10% when I install the exit filter, but it's not really an issue in my application.

**Q: What is the best way to connect this to 12 or 24 volt system?**
A: AC infinity, also looking for DC system compatibility off grid use with solar and lithium battery banks.  Want to avoid DC->AC->DC to save wattage.  I like that your fan design is efficient, but not in my case as the conversion costs wattage/heat.  Ended up buying Atwood unit which does 12/24v which is no where near as nice a fan as this...

*by C***R on 7 February 2021*

For me the ac infinity fans were a game changer, got my environment dialled in just how I need it and with ease to, I purchased an s6 and a t4 reasonably priced I might add, they work perfectly together! These fans are great quality and I was even more pleased when they already came with a connector attached to a U.K. plug! Overall 10 out of 10 for these fans, hats off to AC infinity, they’re so quiet and just a quality product, I will never use another make again, if you’re thinking about buying one just do it, you will not be disappointed
