JB Vacuum Pump Size?
I'm trying to decide on which size JB pump to get. It mainly used for resi and on occasion some larger commercial units, but mainly residential. I was deciding between the 1.5 and 3 CFM. o I already have a 5 CFM pump that is older and am looking to upgrade. I just don't want to get a oversized pump to reduce the risk of producing ice when evacuating...or should i get another 5 CFM....
I've read the manufactures recommendations but wanted to know what works best real work situations.
