I'm intrigued by this post as I had a hankering to re-purpose an old airconditioner's pump for bagging etc.

I am a little confused as to where the two grey cylinders are from. I assume they are tanks used to maintain some "store" of vacuum? (much like a compressor in reverse?)

Would my old ac unit have these? If not, where to source and are there guide line on volume / strength etc to be followed?


thanks in advance!

This set up should work with any pump arrangement as it basically controls the power to the pump.
Only thing to take note of is the start up currant for you pump and ensure that the relay is man enough,
The small white tank is 1nch water pipe and acts as a check to stop the pump trying to start with a vacuum as this it can stall the pump.
The two gray tanks I used some soil pipe that was lying around with end caps. Each is 100mm diameter x 300mm length
They give some back up vacuum that smooths the operation and aids having to run the pump more than necessary.
I bagged some 1.75mt wings and with a good seal on the bag the pump ran for less than 30 seconds over the 12 hours.
To give some idea of scale my unit measures 400mm wide, 250mm deep. 300mm high.
Hope that helps

By the way the wings are for my PIK 20.
