Fog/Jet and non-aspirated nozzles have longer throwing distances than aspirated nozzles for equivalent flow and pressure. They are especially preferred in areas where combined water and foam use is in question. Aspirating nozzles are preferred when direct foam use is required. In aspirating nozzles, the solution and air meet in the monitor barrel and the finished foam (expanded foam) is ejected from the barrel. Relatively shorter firing distances. It is recommended to use film-forming foams with non-aspirating Fog/Jet nozzles.
Depending on the intended use and hazard group, the nozzle type of the monitor is determined. Nozzles used in monitors can be supplied as direct jet nozzles or fog/jet nozzles. Nowadays, monitors are often selected to include fog/jet nozzles as they provide better firing range. If the selected Fog/Jet nozzles have the ability to calibrate the flow rate on the barrel of the nozzle, the installation will be extremely flexible and efficient.
