Beware of youtube videos about connecting 2 compressors together

This is interesting. In theory, would the CFM capacity of the compressors be additive? In other words, would two 10cfm compressors provide 20 cfm in this configuration?

Also, is there a good schematic out there that shows the dummies like me how everything is actually connected? Or is it really as simple as running the two motors off of the same pressure switch, so when the tank comes up to pressure, it shuts them both off at the same time?

I'm sure capacity would add. I see no reason it would be diminished.

So far as electrical, re-read what Bill did. The original pressure switch is not heavy enough to operate both motors. IF that were the case, yes, you could simply wire both motors to the same switch. What he did was use the pressure switch to operate a larger contactor (relay) which DOES have large enough contacts

Of course doing so, at some point, you need enough "oomph" with your electrical service to the garage!!!!
