I have 2 vacuums pump, one of them is original vacuum pump ( 1 hp) I use it for small systems , Another one I made it from bittzer compressor ( 4 hp ) I use it for large systems
Both of them go to deep vacuum and sometimes I use it for recovering gas.
The reason Why I use Air Compressor is , moisture is not effect and damage it and I had in my work shop.
If in your work shop you have air compressor you can test it . open discharge side , connect your manifold to suction side then measure it , might is not very deep vacuum but you see it is good vacuum.
hi there i do know there is a reason for us using vaccum pumps in our industry and as nike 123 said u need 2 boil out all the water!!! a standared air comp is not desigend for this job and i really dont know to what level of vaccum it will go ,so i would rather save time and use the appropriate machine for the job and be on safe side .
