Vacuum Desiccator made of PVC pipe

[chy_farm]

I have a rotary vane vacuum pump that I use for complex wood-working. I also fabricate and do R&D work for loudspeaker design. Thanks for the fruitful ideas. It makes me think.

Good morning @mwmkravchenko, you seem to have a nice vacuum pump there. I too have one here, one made in France;

This one gives me a tad more bigger vacuum than the one I posted lately above.
The previous one is an oil-less pump for vacuum freeze drying, which I got basically for my another homemade-vacuum-freeze-dryer
project, but it's been on the shelf for more than five years, lol.
