Cant beat free , as cheapest price
I'm surprise that most video I see online make use of 200-600$ dedicated vacuum pumps.
Were there are so many source of free freon compressor
Mine cost me 0$
It is the Freon compressor from a 12000btu split unit i found in the trash. Control board in the unit was fried
Refrigerant line were cut , so I had no Freon to adequately dispose.
Any household traditional unit will also have similar compressor .
If the Freon of the unit have already leak ...the unit buzz...but no cold come out , you may have a great donor.
Newer inverter type compressor might be more tricky to salvage from , as you may need to savage the 3phases inverter too , to make the compressor work.
They do "stink" for a wile in the first usage , because the remaining oil in the freon is spited out ,,, It will eventually stop
I've use it for years , for vacuum castings metals, and plaster
I do squirt a pinch of oil in the intake from time to time to lubricate the internal
From seen many vacuum filtering on YouTube ,,, my pump does waaaay faster vacuum !
