Summary:A nozzle assembly for a fire suppression system includes a body having an inlet end for receiving a flow of fire extinguishing agent from the fire suppression system at an inlet pressure and a nozzle portion extending from the body. The nozzle portion includes an interior cavity having an outlet end, a center body arranged within the interior cavity adjacent the outlet end, and a plurality of exit orifices formed in an outer wall of the nozzle portion, in communication with the interior cavity, for vectoring the flow of fire extinguishing agent exiting therefrom and to reduce a noise level of the nozzle assembly. At least one perforated filter member is positioned upstream from the plurality of exit orifices formed in the nozzle portion, for reducing the inlet pressure of the flow of fire extinguishing agent.
