Nozzle Selection Guide
How to choose the correct nozzle?
Choosing the correct nozzle is important for the output and smooth function of your high pressure cleaner.
Nozzle too small = machine permanently switches into bypass or off
Nozzle too wide = machine has a small output, lower pressure
- Make sure you know the flow and pressure of the high pressure cleaner e.g. 15 l/min at a working pressure of 3000 Psi
- On the second row, find the nearest pressure to 3000 psi i.e.2900 Psi
- Flow the column down to the nearest flow to 15 l/min i.e. 14.6 l/min.
- Look left to the first column
- The nozzle size you need is 045
What does “orifice” mean?
What does the “045” in a 25 045 Nozzle mean?
The”045” is a reference point In defining the orifice size of a Nozzle. All Spray Nozzles are rated at a flow point in USGPM rated at 4000psi. Examples to help understand: an 045 nozzle delivers 4.5USGPM at 4000Psi – an 060 nozzle delivers 6.0USGPM at 40000Psi – an 030 nozzle delivers 3.0USGPM at 4000Psi
Tip Angle
0° Blasting Nozzle
This nozzle delivers a very concentrated stream of water. Care should be used to avoid gouging wood or damaging fragile surfaces.
Uses: Removing weeds from sidewalk cracks, stubborn stains from concrete, masonry, aluminium & steel, caked mud from equipment and mower decks
The spray should be directed at a 45 degree angle to the surface and used like a scraper to remove paint, grease & dirt.
Uses: Surface preparation (removing peeling paint & mildew stains, cleaning gutters & downspouts).
25° Flushing Nozzle
With a narrower spray pattern than the 40° nozzle and with a more concentrated spray pressure, this nozzle is best suited for flushing dirt, mud & grime.
Uses: Wet sweeping leaves from walks, curbs & driveways, cleaning stable floors. Washing the bottom of swimming pools & blasting BBQ grills
40° Wash Nozzle
The wide spray pattern disperses water over a large area and is recommended for rinsing and moderate washing.
Uses:Washing down aluminium siding, cleaning windows, washing vehicles, spraying sidewalks, drive ways & patios
Turbo Nozzles
Turbo Nozzles spray water out of 0° orifice. The spray exits the nozzle at an angle while rotating. This rotation allows the spray to simulate a spray pattern, therefore, it allows the operator to cover a larger area. With the increased tearing action of the rotating spray, the turbo nozzle handles caked on mud, peeling paint, concrete cleaning and other applications where a flat fan wont cut it.
Soap / Detergent Nozzle
Used for low pressure spraying. This nozzle will allow a soft spray soaking of the surface with a liquid soap or detergent.
Uses: Equipment cleaning, removing mildew & oxidation stains from houses, cleaning effervescent brick & degreasing.
Effective Working Pressure (EWP)
Effective Working Pressure is a meaningless number designed to mislead. In the Australian market, some use the term EWP to create the impression that a pump can dramatically increase the performance of a machine by adding a Turbo Nozzle i.e. the pump on a pressure cleaner may be rated to 3000Psi and some say by adding a Turbo, the EWP increases to 4500 Psi. Our comment on this: You cannot change the engineering capabilities of a pump simply by adding a device such as a Turbo to the end of a lance. The turbo actually increases your cleaning speed, not your pressure.
