re: Corsi-Rosenthal Air Filter Box

Nice write-up, Nathan! I’ve been getting cranky with my ceiling-mounted Rikon filter. They strongly dis-recommend modifying it to be always on, because (according to the tech support person I talked to) if the filters get clogged, the unit will shut down rather than overheating the motor. But I really want a ceiling-mounted unit I can hardwire to the same circuit as the shop lights so it’s always on when I’m working.

Also, the cost of the replacement filters for the Rikon is pretty high. I think I’ve got five filters left to “use up” before I retire it for something like what you’re playing with.
