Foamjet Lx With Masterstream Nozzle; Flow Characteristics Of Masterstream Selectable Nozzle - Task Force Tips ZN Series Instructions For Installation, Safe Operation And Maintenance

2.4.1 FOAMJET LX WITH MASTERSTREAM NOZZLE

To increase the expansion ratio and drain time, Task Force Tips "Foamjet LX" (model FJ-LX-M) may be used with the Masterstream
nozzle. This low expansion foam tube attaches and detaches quickly from the nozzle. Note: As expansion ratio is increased, the
reach of the stream will be decreased due to the greater amount of bubbles in the stream and their inability to penetrate the air.
Generally, the reach with foam is approximately 10 % less than with water only. Actual results will vary based on brand of foam,
hardness of water, temperature, etc.

3.0 FLOW CHARACTERISTICS OF ZN & ZM NOZZLES
The ZN & ZM Nozzles are manufactured to a predetermined fi xed orifi ce. The orifi ce size is not adjustable and is specifi ed at time
of order. 250, 350, 500 or 750 GPM fl ow rates at 100 PSI are available on the ZN and 500, 750, 1000 or 1250 GPM @ 100 psi are
available on the ZM nozzle. The fl ow rate is marked on the nozzle's baffl e. Figure 3 gives relationship of fl ow and pressure for various
orifi ce sizes.
3.1 FLOW CHARACTERISTICS OF MASTERSTREAM 1000 SELECTABLE NOZZLE
The Masterstream 1000 Selectable Nozzle allows the user to select one of several orifi ce sizes by turning a knob at the front of the
nozzle. An indicator on the knob shows which fl ow has been selected. Figure 3 gives relationship of fl ow and pressure for various
orifi ce sizes.
