The Hollowcone consists of an orifice plate with a swirl core postioned in front, the two forming an intermediate swirl chamber. Liquid passes through the helical slots in the swirl core, and into the swirl chamber where the liquid acquires a high rotational velocity, discharging from the orifice in a hollow cone spray form. Rated at 3 bar pressure, these nozzles produce a bimodal distribution. The swirl core is a push-fit into the orifice plate and becomes captive. It is easily removed with a key.
