ESCRIPTION
The Flex Attack
®
Nozzle has been designed primarily to give a fire-fighter a distinct advantage
in the application of Compressed Air Foam (CAF). The patented variable orifice waterway
allows the fire-fighter to adjust discharge sizes without shutting down, depending on the
requirements of the specific situation. The nozzle has been designed to flow water, wet CAF,
dry CAF, and anything in between.
A. Shutoff
The shutoff portion of the Flex Attack
®
nozzle features a dual drive, double seat shutoff with a
full round metal ball. The nozzle is manufactured standard with a 1.5” NH thread free swivel
inlet and an aluminum/bronze horseshoe shutoff handle. A Teflon
®
impregnated, hard
anodized aluminum pistol grip is also standard on the shutoff body. Special thread and handle
configurations can be addressed upon request.
B. Pressure Balancing Mechanism
This patent pending mechanism allows the nozzle to adjust between discharge orifice settings
under normal working pressures within the 40 in-lbs as required by NFPA 1964. This feature
also allows the nozzle to be fully adjusted from largest discharge orifice to the smallest in only
120 degrees of rotation. This portion of the nozzle is protected by a heavy-duty Santoprene
bumper to increase the fire-fighter’s ability to grip the nozzle.
C. Nozzle Tip
The Flex Attack
®
nozzle tip is constructed from Teflon
®
impregnated, hard anodized aluminum.
The tip includes an indicator lug to give the fire-fighter tactile feedback on the discharge
positioning. The tip includes a set of colored labels for convenient discharge line identification.
See instructions sheet in label packet for details on label installation.
D. Variable Orifice Waterway
The patented variable orifice waterway enables the user to vary the discharge size of the
nozzle depending on the technique required to fight a fire. The variable orifice waterway
creates a fully open, unobstructed waterway in all three positions. This consists of a Zytel
®
ST801 adjustable center barrel and a 70A durometer compressible bore. The waterway can
be adjusted to three convenient discharge sizes.
Discharge Orifice Size
Setting Size (inches)
Water 15/16
Wet CAF 1 1/8
Dry CAF 1 3/8
