TFT has a great advertising and marketing department and people that come up with fancy ideas that aren’t needed and make the nozzle impractical from the experience I’ve had with them.
We have the Elkhart Fire Chief 50psi/150gpm on our 1.75” and 50/250 on our 2.5”, 15/16” snoothbore on our high rise packs.
I’ll always take a fixed gallonage over an automatic as another poster pointed out, automatics give you a great stream but you’ll have no idea what you’re flowing,. A fixed gallonage will have stream degradation letting you know there’s a problem somewhere. The pump operator can over or under pump you a little if you want to change your flows, not a fan of adjustable flow nozzles as I’ve seen them get accidentally moved to a different setting and neither the nozzleman or Engineer were aware.
He new Fire Chief XD are a little nicer and the fog is a 50/160 to match with a 7/8” smoothbore which will do the same flow at that pressure making it nice on your Engineer.
