Description
Discharge nozzles are designed to direct the discharge of
INERGEN
®
agent using the stored pressure from the cylin-
ders. Ten sizes of nozzles are available. The system design
specifies the orifice size to be used for proper flow rate and
distribution pattern*. The nozzle selection depends on the
hazard and location to be protected. Standard nozzles are
constructed of brass.
NOTE: 2, 2 1/2, and 3 in. nozzles are not recommended in
areas that are subject to damage by high velocity dis-
charges, such as suspended ceiling tiles.
* Orifice diameter must be specified when ordering nozzle.
