Quote:Large foam concentrate loading/unloading device; just a guess.Yes, for 500 gal Foam totes. (no more moving cans)
This piping allows the hook up and changing of multible totes and to be able to flow from them with out interrupting the foam supply. This is needed for the large capicity foam flows.
Also the Malvern Mack B is the first Mack B-75 (#1001)
I am not sure if it is the first B Mack because there was also B-85 & 95 (and a few others)
