Lance Jet (III)
These fountain nozzles are similar to the two previous models in terms of their operating principle. The differentiating factor is that this model uses more economical materials and manufacturing techniques than the previous two series. In this model, the brass body is replaced by an AISI 304 stainless steel casing. Because the previous series have a smaller deflection cone at great heights, they perform better; however, for the first three quarters of the water jet height, they both provide similar quality. They are supplied with an outer swivel joint or with no joint. The outer joint produces better-quality parabolic jets because the joint has an additional jet locator..
