ALL YOU WANT TO KNOW ABOUT PRESSURE WASHERS
NOZZLE SIZING CHART
Size are listed vertically on the left. The PSI rating is
listed across the top, left to right. Under each PSI rating the gallons per
minute (GPM) allowed by the orifice will be listed vertically. To match the
nozzle orifice to your systems requirements begin by finding the PSI rating on
top. Follow this column down until you find the gallons per minute rating of
your pump. Look to the left colum and find the orifice size required by your
system.
If the nozzle size is too small, your equipment can be
damaged from overpressure. If the nozzle is too large, cleaning ability is
compromised.
Nozzle fan degree does not effect nozzle size selection.
