2.0 GENERAL INFORMATION
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 250, 350, 500 or 750 GPM. Fog angle is user
adjustable between 90° 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 MASTER FOAM 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 MASTER FOAM self-educting nozzle is hardcoat anodizedANSI 356-T6 aluminum. All MASTER FOAM
nozzles accept the FJ-LX-M FoamJet low expansion air-aspirating attachment.

3.0 NOZZLE OPERATION
3.1 NOZZLE COUPLING
The MASTER FOAM 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.
CAUTION Nozzle threads must be mated correctly. Mismatched or damaged threads may cause nozzle to
leak or uncouple under pressure and could cause injury.
CAUTION Donotcouplealuminumtobrass.Dissimilarmetalscoupledtogethercancausegalvaniccorrosion
that can result in inability to unscrew the threads or complete loss of thread engagement.
3.2 FLOW CHARACTERISTICS
Figure 2.1 gives the flow characteristics of the MASTER FOAM 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.
CAUTION 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.

3.3 PATTERN CONTROL
The MASTER FOAM’s spray pattern is adjustable from straight stream to a 90° 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° of rotation is required to go from wide fog to straight
stream. The widest pattern is useful for protection and cooling but doesn’t educt foam.
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.

3.4 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).
WARNING 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.

3.5.1 CLASS A FOAM
It is recommend that the Class A foam used meets USDA Forest Service 5100-307A “Specification for Fire Suppressant Foam for
Wildland Firefighting (ClassAFoam)”, NFPA298 “Fire Fighting Foam Chemicals for ClassAFuels in Rural, Suburban, and Vegetated
Areas”, or NFPA 1150 “Foam Chemicals for Fires in ClassA Fuels”.

3.5 USE OF FOAM
Refer to fire service training for the proper use of foam.
WARNING 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. Foam pickup in the 90° wide fog
position is not guaranteed to function. 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
WARNING 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.
WARNING 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.

3.5.2 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 MASTER FOAM 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 concentrate. The orifice plates
for the MASTER FOAM nozzle have been calibrated at 70 degrees F as follows:
PERCENT FOAM USED FOR CALIBRATION
0.5% and 1% Class A foam of 20 centipoise viscosity
3% 3M ATC 3 AR-AFFF product code ATC-603
6% 3M ATC-AFFF product code FC-600F
CAUTION Foam pickup in the widest fog position (90°) is not guaranteed.
3.5.3 CONCENTRATE HOSE CONNECTION
Remove the nut on top of the percentage knob and lift the knob to select the proper foam concentrate type. Replace the knob nut.
Turn the knob to the desired concentrate percentage. The percentage knob may be turned to the OFF position for water only use.
Be sure to use the foam manufacturer’s recommended concentrate ratio.

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:Asexpansionratioisincreasedthereachofthenozzle
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.
3.5.5 CLEANING AFTER USE
After educting foam it is recommended that water be
educted in through the concentrate hose and inlet. This will
washoutfoamconcentrateresidueinthehose,orificeplate,
and nozzle passages. If not removed, any residue may dry
and adversely affect the accuracy of proportioning.
3.5.6 USE WITH SALT WATER
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

Hose Connection
4.0 MAINTENANCE AND INSPECTION
WARNING The nozzle may be damaged if frozen while containing sufficient amounts of water. Such
damage may be difficult to detect visually and can lead to possible injury or death. Any time
the nozzle is subject to possible damage from freezing, it must be hydrostatically tested by
qualified personnel before being considered safe for use.
The MASTER FOAM 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.
