Fyrhed High Velocity Nozzle

The GW Sprinkler Fyrhed high velocity nozzle is designed for directional spray applications in fixed water spray (deluge) systems.

The Fyrhed nozzle produces a soild, uniform and highly robust cone of high velocity water spray, generated as the pressurized water passes through the internal swirl plate, rotating/spinning the water jet as it exits the nozzle orifice.

The high velocity Fyrhed nozzle is available in a variety of K-factors and materials, to meet most land based and off-shore design application requirements.


GW Fyrhed - High Capacity is currently the largest high velocity nozzle in the Fyrhed-family. It is developed to provide a dense 100° full cone spray for extreme applications where excessive application rates are called for. With a K-factor of 210, this 1" nozzle delivers 210 liters per minute @ 1 bar pressure.
