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 fi xed orifi ce fog nozzle rated at 100 PSI is available with a fl ow range of 250, 350, 500 or 750 GPM. Fog angle is user
adjustable between 90° wide fog and straight stream. The nozzle's baffl e is removable for fl ushing 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 orifi ce plate. The nozzle comes with an 8 foot long 1.5" diameter concentrate
hose with a 1.5" camlock fi tting (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 anodized ANSI 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.
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
CAUTION
that can result in inability to unscrew the threads or complete loss of thread engagement.
3.2 FLOW CHARACTERISTICS
Figure 2.1 gives the fl ow 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
fl ow entering the nozzle. Any foam educted will add to this fl ow.
An inadequate supply of nozzle pressure and/or fl ow will cause an ineffective stream and can result in

injury, death or loss of property. See fl ow graph or call 800-348-2686 for assistance.
