AR4747 (1.5) Mixing Chamber
This is a top quality mixing chamber. This chamber was designed to work with the Fusion AP Gun. This chamber has a round pattern, with .47 orifices. It has a 11.5 inch spray pattern, when you are 2 feet from your target. The output of this chamber is 14lbs/min. This chamber is great for wide open jobs. It allows you to put a lot of foam on sub-straights fairly quickly, compared to the other chambers.
This chamber maybe a little much for wall cavities, or machines that are equivalent to E-20 size or smaller. (The heaters may have a hard time keeping up to the output of the chamber)
