Stream quality and reach, especially with stacked tip (smooth bore) nozzles, is generally improved with stream straightener because
the water must make many bends before it reaches the nozzle.
6.7.2 STREAM STRAIGHTENERS WITH FOG NOZZLES
When using a fog nozzle it is recommended that no stream straightener be used since the fog nozzle's flow path generally serves as a
stream straightener. Use of a stream straightener with a fog nozzle will increase the stresses on the monitor's gear train and may lead to
premature wear.

6.6.2 AUTOMATIC NOZZLES
Automatic nozzles maintain a constant pressure by adjusting their orifice to match the available flow. Consult the nozzles manufacturer
for maximum flow and pressure ratings. In all cases, do not exceed 1250 gpm (5000 L/Min). TFT's Masterstream 1250 Nozzle has a
150-1250 gpm (600 - 5000 L/Min) flow range. Masterstream 1250 Nozzle operating instructions (Item Number LIM-030 is available on
TFT's website: www.tft.com.
