Proper nozzle size is important to get the most from your pressure washer.
Having a pump of 200 l min at 1540 bar a 6 rear jets nozzle and a 10 pressure loss it is possible to calculate holes diameter as follows.
I know how confusing it must be selecting the proper pressure washer nozzle size.
To find the correct nozzle size you need to know the flow of your system and the pressure you wish to achieve.
Rotary nozzles are great for use on stubborn stains wall cleaning paint stripping and more.
Let s say the calculator says you re in between sizes and the nozzle size is 2 79.
The incorrect size would affect the pressure and either reduce it or even break the machine.
Determine the proper nozzle size by the pressure washer s gpm gallons per minute at a specific psi.
Most in gallons per minute and pressure output.
Follow this column down until you find the gallons per minute rating of your pump.
Pressure washer rotary nozzles act as a zero degree tip that sprays in a circualar motion.
Enter your units flow in gallons per minute in the pump flow box.
This chart will assist you with the selection of the proper nozzle size.
If the nozzle size is to large your cleaning ability will be reduced.
P 150 bar 10 pressure loss 135 bar.
Choosing a nozzle with too large of an orifice will reduce operating pressure.
Choosing a nozzle with too small of an orifice will limit water flow and possibly create an excessive load on the machine.
This is actually the most important factor as the incorrect size would affect the pressure and either reduce it or even break the.
Please note that nozzle fan degree does not effect nozzle size selection.
Using the calculator below enter your rated gpm and psi of your pressure washer.
