SE Water foam nozzles give the option of projecting water or secondary aspirated (also called unaspirated or non-aspirated) foam over long distances. Normal or primary aspirated foam cannot be projected over a long distance, and hence has limited range. SE Water Foam nozzles produce secondary aspirated foam, which typically have expansion ratios of around 1:3 to 1:4, and being more dense, this foam can be projected further as compared to normal foam. When properly used, these nozzles can be useful in tackling large flammable liquid fires. Convenient Swivel type inlet suitable for use with 2.5”, 3”, 4” and 6” size monitors. Supplied with matching Pickup tube and piercer.
