Nozzle Size / Flow Rate (To find the right size Nozzle)

To find the right size nozzle look along the "TOP LINE" and find the Pressure output of your pump in bars.

Then follow the line across to the left and fine the nozzle size in the left hand column.

General Info and the Importance of Sizing the Orifice of pressure washer nozzles

Impact pressure is highest immediately on exiting the tip.
Impact pressure decreases the further pressure washer nozzles are from the surface being cleaned.
The most efeective cleaning distance is from 4"-12".
Increasing the size of a nozzle orifice effectively lowers the pressure produced while maintainig the flow output of the pump.
