My dust collection uses a Festool CT MIDI (connected to a cyclone separator),
and I have been very happy with it EXCEPT one extremely irritating detail.
I have it plugged on my (very DIY ) power control panel, behind the “shopvac” switch:
BUT that Festool model only has a momentary push switch for on/off, so it won’t start when “just” supplied from mains. One has to push that button right there to manually start it:
which defeats the purpose of me having it placed underneath my Shapeoko, inside a soundproof enclosure.
The only other way to have it start is using the auto-start, that’s when it detects that something plugged in the output power plug is drawing power:
This is quite convenient when using a power tool plugged there (the Festool will start and stop automatically when one uses the tool), but in my case it means that the only way I can have it start when I flick that 220V power switch, is by plugging some load there.
A few tests revealed that it took about 15-20W to trigger the vac. I wondered what I could use (permanently), that would not be a total waste of 20Watts. And finally I settled on this air extractor:
It draws about 20W, so it does trig the Festool, and is something I have been wanting to do for a while: add active air extraction from the lower part of my enclosure, because on hot days and long runs, it was getting hot in there.
Ok, one item crossed off the todo list, 5967 items to go.
