Cardox fog Aque sno foam Nozzle Chicago Fire airport? Unusual and hard to find water cannon. Not sure of original use. I suspect it might have been used to de-ice airplanes but I do not know. Show some obvious signs of use and discoloration.I have no idea if it would actually work. I see no reason why it wouldn't. This company still makes fire suppression items. Lots of quality workmanship in this. Will need some cleaning if desired.
Price will come down be sure to watch.
