Precicely, I kinda lumped them all in the same type category. It is all
about the CFM of the pump and not so much the tank size. But for the
most part the bigger the tank the less the pump has to recharge.
I once bought an 80 gallon compressor from a garage sale, it had a tiny
single piston pump. It literally took approximately 45 minutes to fill
from no pressure. Obviously it was a "piece it together" affair. I was
glad to sell it and downsize to a "New" compressor 20 years ago. LOL
