Hi I'm ready to buy my vacuum pump
And I am looking for a ROBINAIR whit 3 CFM and 1/3 hp for $440.00 dlls
or a budget vacuum pump (refrigerator compressor) for $100 dlls
but just not sure if the ROBINAIR pump its to much for just doing wood-core boards and divinycell cores.
or if a refrigerator compressor its just enough for this task.
did some one knows how much presure can pull on vacuum bag each one of this pumps???
I need to run the pump for 8hrs or more,,,, so the refrigerator compressor can handle this???
