I currently working on a box-fan air cleaner project which will hang from the ceiling. I want to preserve the speed controls, if possible, but I'd like to add a time so that it will run for an hour after I'm done making dust (yea, I do have a DC plumbed to everything but 'fines' tend to get away). The real problem is that the AC access is on the ceiling where the lights are plugged in. If I could mount the timer to the bottom of the fan I will be able to reach it without a ladder. I would prefer a self contained unit so that I don't have to get into running conduit and installing a box for the typical bathroom type timer. Do any of you folks have any experience with such a device?
As always, TIA! Chuck
