AC Infinity CLOUDLINE PRO S4 Silent 4" Inline Duct Fan with Speed Controller Heating and Cooling Fan Promotes Cooling Growing Tent Hydroponics

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?

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?

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?

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.
