Description

- Hollow cone spray pattern with a circular impact area - Large, unobstructed flow passages minimize clogging - Good atomization of liquids at lower pressures – ideal for fluid cooling applications - Removable caps for easy inspection and cleaning on some models - Slope-bottom design models reduce the drilling effect of the fluid vortex in the fluid chamber and premature wear - AX and BX nozzles form smaller drops; ideal for use in air washers and dust suppression applications - CX, CF, CRC and D nozzles feature higher flow rates; ideal for use in larger, evaporative cooling spray ponds - AP, LAP and LBP nozzles are constructed of polypropylene and feature excellent corrosion resistance at temperatures up to 160°F (71°C); patented center post design provides extended wear life of the nozzle - Standard, wide and extra wide spray angles **Flow:** As liquid enters the nozzle, it passes into a whirlchamber and begins to spin in a circle at high speed. The rotation forces the liquid away from the center toward the edges of the whirlchamber. This causes the liquid to exit the orifice in a hollow cone pattern. Some WhirlJet nozzles have a slope bottom in the whirlchamber that helps extend wear life.
