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.

2.3 PATTERN CONTROL
The 's spray pattern is adjustable from straight stream to a 90 degree wide fog. Turning the
stream shaper clockwise (as seen from the operating position behind the nozzle -see figure 2.3) moves the
shaper to the straight stream position. Turning the shaper counterclockwise will result in an increasingly wider
pattern. Only 90 degrees of rotation is required to go from wide fog to straight stream.
Since the stream trim point varies with flow, the stream should be "trimmed" after establishing a steady flow. To
properly trim the stream, first open to a narrow fog. Then close the stream to parallel to give maximum reach.
NOTE: Turning the shaper further forward will cause stream crossover and reduce the reach of the nozzle.
MASTER FOAM
2.4 FLUSHING DEBRIS
Small debris in the water may get caught inside the nozzle. This trapped material will cause poor stream quality,
shortened reach and reduced flow. To remove debris trapped in the nozzle:
• Shut off flow to the nozzle.
• Unscrew baffle (see figure 2.3) using 1-1/8 inch (28mm) socket.
• Remove debris. Flow water to flush if necessary.
• Reinstall baffle.Tighten to approximately 30 ft-lbs (40 Newton-Meters).

Large amounts of debris may be unflushable and can reduce the flow of
the nozzle resulting in an ineffective flow. In the event of a blockage, it may
be necessary to retreat to a safe area.
Larger debris can get caught in the nozzle ahead of the cast vane. If this occurs uncouple the nozzle to clear
the blockage.
WARNING

2.5 USE OF FOAM
Refer to fire service training for the proper use of foam.
There are a wide variety of foam concentrates. Each user is responsible for
verifying that any foam concentrate chosen is suitable for the purpose
intended.
Improper use of foam can result in injury or damage to the environment. Follow
foam manufacturer's instructions and fire service training to avoid:
• Using wrong type of foam on a fire, i.e. Class A foam on a Class B fire.
• Mishandling of concentrates, some of which are flammable.
• Plunging foam into pools of burning liquid fuels.
• Causing environmental damage.
• Directing stream at personnel.
For Class B fires, lack of foam or interruption in the foam stream can cause a
break in the foam blanket and greatly increase the risk of injury or death. Make
sure that:
• Application rate is sufficient (see NFPA 11 or foam manufacturer's
recommendations).
• Enough concentrate is on hand to complete the task (see NFPA for
minimum duration time requirements).
• Foam logistics have been carefully planned. Allow for such things as:
• Storage of foam in a location not exposed to the hazard it protects.
• Personnel, equipment and technique to deliver adequate foam.
• Removal of empty foam containers.
• Keeping clear path to deliver foam as hoses, other equipment and
vehicles are deployed.

2.5.1 FOAM SELECTION
See figure 2.5.1 for a summary of typical uses for various foam types.
2.5.2 SETTING FOAM PERCENTAGE
The foam percentage is controlled by an orifice plate that is installed in the nozzle at the mouth of the concentrate
inlet (see figure 2.5.3). The comes with orifice plates for 0.5%, 1%, 3% and 6%. Each orifice
plate is marked with the percentage and nozzle flow rate. The flow rate on the orifice plate must match the flow
rate marked on the nozzle's baffle. The chart in fig 2.5.2a gives the nominal rates of foam usage. Accuracy of
proportioning is fairly insensitive to nozzle inlet pressure. The graph in figure 2.5.2b gives expected percentages
for various inlet pressures.
To install the orifice plate in the nozzle simply push it into the bore at the concentrate inlet on the nozzle. The
orifice plate has an O-ring to hold it in place.
To remove the orifice plate, hook a small object (such as a screwdriver or Allen wrench) into the hole in the
orifice plate and pull it out. Take care not to damage the orifice. Note: The hole in the 6% orifice plate is big
enough that your finger can be used to pull it out instead of a tool.

Note: In any eductor type system the accuracy of proportioning depends on the viscosity of the foam

2.5.3 CONCENTRATE HOSE CONNECTION
The concentrate hose is attached to the nozzle by a 1.5 inch cam lock fitting (Military
Standard: MS 27019). Orient levers to avoid interference with the stream shaper and push the fitting onto the
concentrate inlet on the nozzle. Fold both levers until they touch the hose to lock. The other end of the hose is fed
into a foam container. An optional hose is available with female camlock fittings on each end. Hose connection
and typical set ups are shown in figure 2.5.3a and 2.5.3b.

3.0 MAINTENANCE AND INSPECTION
The self-educting nozzle requires no routine maintenance. The shaper seal slides on a plastic
surface and requires no grease. The nozzle should be inspected regularly to assure proper operation. In
particular, check that:
• Coupling and gasket are tight and leak free.
• The desired orifice plate (flow and percentage) is installed.
• Concentrate inlet hose and gasket are damage and leak free.
• Flow passages are unobstructed.
• Baffle is in place and tightened securely.
• Shaper moves freely.

2.5.4 USE OF FOAMJET LX
2.5.5 CLEANING AFTER USE
2.5.6 USE WITH SALT WATER
To increase the expansion ratio, Task Force Tips' "Foamjet
LX" (model FJ-LX-M) may be used. This low expansion
foam tube attaches and removes quickly from the nozzle.
Note: As expansion ratio is increased the reach of the
nozzle will be decreased due to the greater amount of
bubbles in the stream and their inability to penetrate the air.
Figure 2.5.4 gives approximate stream trajectory
information with and without Foamjet LX. Actual results
will vary based on brand of foam, hardness of water,
temperature, etc.
After educting foam it is recommended that water be
educted in through the concentrate hose and inlet. This will
wash out foam concentrate residue in the hose, orifice
plate, and nozzle passages. If not removed, any residue
may dry and adversely affect the accuracy of
proportioning.
Use with salt water is permissible provided nozzle is
thoroughly cleaned with fresh water after each use. The
service life of the nozzle may be shortened due to the
effects of corrosion and is not covered under warranty.
For saltwater compatibility with foam, refer to supplier's
technical data.
