Stream quality and reach, especially with stacked tip (smooth bore) nozzles, is generally improved with a stream straightener because
the water must make many bends before it reaches the nozzle.
6.6.2 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 stress on the monitor's gear train and may lead to
premature wear.

6.5.2 AUTOMATIC NOZZLES
Automatic nozzles maintain a constant pressure by adjusting their orifice to match the available flow. Consult the nozzle’s
manufacturer for maximum flow and pressure ratings. In all cases, do not exceed 1250 gpm (4500 l/min). TFT's Masterstream 1250
Nozzle has a 150-1250 gpm (600 - 4500 l/min) flow range. Masterstream 1250 Nozzle operating instructions (Item Number LIM-030)
are available on TFT's website: www.tft.com
