Nozzles selection table for the fire safety industry

 

The table below summarises much of the information in the flat fan nozzle section of the SNP website.  It is intended to be 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 their own tab to allow for easy comparison of several different nozzle types
