The C-4 has 550 CFM. This is plenty of CFM to run two wands with
glides on them.
Les, how far is that "550 cfm" measured from the machine?
Is there an industry standard for taking those measurements, ie; 100, 150, 250 ft from the machine? Manufacturers advertisements never say how far it's measured from the machine.
I've always wondered if the CFM's advertised are taken 10 ft from the machine or real world conditions 150 ft or more from the machine, on the second floor of a house with lots of bends and turns down the hall, down the stairs, over the cat, right turn at the front steps, left turn at the driveway...
550 CFM sounds great but it sucks if you are dual wanding ft expecting to get quick dry times with each hose run 200 ft from the machine and you are only pulling 180-200 CFM's per wand. You might as well run 2 single wand machines with 2.5 inch hose, right? Then you have the added expense of a 2nd van with insurance, registration, maintanence etc.
Damned if you do, damned if you don't...
Thanks,
Bill
