[quote author="carpin"]The Aoyue 474A++ [Negative pressure (suction) = 600 mmHg = 80kpa Maybe you can use two pumps?[/quote]
Will get a similar gun (if not the same), and a few pumps and do some testing :) thanks!
If this works will be great add-on to the sparkybg universal controller…
Found the same one here… but I used to work with similar desoldering station and was clogging to often… prefer the firs one but it's much more expensive!
[quote author="sparkybg"]It can drive any soldering iron with thermocouple or resistive sensor.
I am just guessing, but I think this desoldering gun is 24V 80W, with thermocouple sensor. So, yes, it can drive it. But you also need a vacuum pump for it to operate. It looks similar to the gun of my ZD915 station:

Thanks for your replay!
Today I was thinking about the same thing - how to drive a desoldering iron with suction! These are useful and can save a lot of time if you work with through-whole or do repair work.
Instead using bigger diaphragm pump, would it work with just electric motor driving smaller diaphragm pump.
Does someone know what is the back(suction) pressure of original diaphragm pump ZD915,Aoyue, Hakko, or Weller? May be would be possible to use something like this:
The first have 50kpa according to it's specifications: Pump quick specifications: [Negative pressure (suction)] - 50kpa [Positive pressure (blowing)] 90kpa [Flow] 2L / min
