Self-inducting air-aspirating foam monitor nozzle (Dispersion jaw) features both self-inducting and air-aspirating functions. Through an inbuilt eductor and pick-up tube, the nozzle introduces foam concentrate into a pressurized water stream. Through an aeration tube, it then introduces sufficient air for mixing with foam solution to produce foam. With dispersion jaw at the tip, it can deliver straight jet, and fan type spray.
