Gph you mean. Almost all rinses are 32oz per 5 gallon jug. (1 quart) 128 oz per gallon, 4 quarts in a gallon, so 1 gallon of rinse concentrate yields 20 gallons of ready to use rinsing agent. So at 2.5 gph 1 gallon of rinse concentrate will yield 8 hours trigger time. Psi doesn't matter . Hope this helps you.How long will a gallon of that rinse last at say 450 psi at 2.5 gpm? I used to just dump the rinse in my fresh water tank, but my new machine has a meter.
I've been using Crystal Rinse from Magic Wand for years. It's a encapsulating rinse and does a great job in my opinion. Use it for commercial and residential. Never get any call backs.I use Matrix All Fiber or Complete, depending on the job. 32oz in 5 gallon tank. Meter at 2-3 GPH. How long it lasts depends on size, number and type of jobs but it seems to last about the same as a 120 gallon tank of fresh water. With all that said, am thinking about trying an encapsulating rinse in the near future.
If you like that combo, I'd suggest AFD instead of AFR because of its encap properties and put yer own isopropanol in it. The iso helps dry times but also helps cut through oily soilI'm using a combo. Last step by cti & prochem all fiber rinse. Last step as a high alcohol content crating faster dry times. All fiber rinse just smells good.
