1.0 GENERAL INFORMATION
1.1 PART IDENTIFICATION
The Task Force Tips MASTER FOAM nozzle is a simple and rugged self-educting foam nozzle with superior
stream quality and reach. This fixed orifice fog nozzle rated at 100 PSI is available with a flow range of 350, 500
or 750 GPM. Fog angle is user adjustable between 90 degree wide fog and straight stream. The nozzle's baffle is
removable for flushing debris. The standard swivel coupling is 2.5" NH, NPSH or BSP female threads. The
Nozzle can educt foam concentrates at 0.5%, 1%, 3% and 6%. Percentage is set by means of
an interchangeable orifice plate. The nozzle comes with an 8 foot long 1.5" diameter concentrate hose with a
1.5" camlock fitting (military standard MS27019) for attachment to the nozzle. The simple and basic design
requires no grease or other maintenance. The halo ring/stream shaper is made from a non-corroding high
temperature polymer. The rubber bumper is UV resistant. The
self-educting nozzle is
available in UNS C83600 brass, as well as hardcoat anodized ANSI 356-T6 aluminum. All
nozzles accept the FJ-LX-M FoamJet low expansion air-aspirating attachment.
Figure 1.1 shows the
nozzle and identifies the various parts and controls.

2.0 NOZZLE OPERATION
2.1 NOZZLE COUPLING
The
nozzle is available with 2.5 inch female threads (NH, NPSH or BSP). When tightening
the coupling, make sure the foam inlet is pointing downward for ease of attaching the concentrate inlet hose.
MASTER FOAM
Nozzle threads must be mated correctly. Mismatched or damaged threads
may cause nozzle to leak or uncouple under pressure and could cause
injury.
Do not couple aluminum to brass. Dissimilar metals coupled together can
cause galvanic corrosion that can result in inability to unscrew the threads
or complete loss of thread engagement.
An inadequate supply of nozzle pressure and/or flow will cause an
ineffective stream and can result in injury, death or loss of property. See
flow graph or call 800-348-2686 for assistance.
2.2 FLOW CHARACTERISTICS
Figure 2.1 gives the flow characteristics of the
nozzle. Pressure on the graph is the nozzle inlet
pressure. Losses through piping and monitor must be taken into account to deliver the desired pressure to the
nozzle. Flow on the graph is the water flow entering the nozzle.Any foam educted will add to this flow.
