Fire extinguishing nozzle selection table
The table below summarises much of the information in the fire extinguishing nozzle section of the SNP website. It is intended to be a handy reference guide to aid nozzle selection. Full data on each of the nozzles listed can be accessed by clicking on the boxes in the left hand column of the table below. The data sheets will open in a separate tab to allow easy comparisons between multiple product sheets.
