Now, of course, using a vacuum supply changes the way the desoldering unit operates, so it would need re-plumbing to eliminate the venturi and make the solenoid valve work for vacuum.
Another thing to consider is the smoky output of desoldering. I recently repaired a Hakko 470, that has
an on-demand vacuum pump, and found the smoke had gummed up the rubber flap reed valves of the pump.
It's a good idea to have some kind of receiver container up stream of the solenoid you use, since it
would be in line to get rosin smoke. Maybe a pipe fitting container with wads of TP in it?
