Softwash spray nozzles designed for controlled low-level chemical application.
Product overview
These nozzles fit our 1/4-inch stainless steel couplings, allowing you to connect them directly to the outlet of Benz low-level and mid-level softwash lances.
The different nozzle tips provide controlled flow and an appropriate droplet pattern for the chemical being applied.
The interchangeable design allows you to change the nozzle quickly according to the chemical, pump flow and surface being treated.
What they’re for
These nozzles support controlled chemical application during low-level and close-range softwash work, including:
- Close-range render treatment, particularly around reveals
- Fascia, soffit and gutter cleaning
- Garden walls and boundary walls
- Paths and patios
- Bin areas and service yards
For high-level chemical application, use our high-level softwash spray nozzles. Their lighter design makes them more suitable for use on water-fed poles.
Available nozzle sizes
Benz low-level softwash spray nozzles are available with three interchangeable tip sizes: 6.5, 10 and 15.
The number stamped on the face of each tip represents its fluid-delivery rating in litres per minute at 6 bar. A higher delivery rating produces a coarser droplet pattern that may help reduce overspray and run-off.
In simple terms, a smaller nozzle number indicates a smaller opening. This increases delivery pressure while reducing the volume of liquid that can flow through the nozzle.
6.5 nozzle
Controlled Bio Cleanze application
The 6.5 nozzle is best suited to applying Bio Cleanze where controlled delivery and good penetration into biological growth are required.
- Best suited to Bio Cleanze
- Recommended flow rate: 2 to 6 L/min at the nozzle
- Suitable for smaller pumps, including 12 V softwash systems, and larger pumps with the flow reduced
10 nozzle
Lightning Cleanze application with smaller pumps
The 10 nozzle provides a higher-flow option while maintaining a controlled droplet pattern that helps reduce spray drift.
- Best suited to Lightning Cleanze
- Recommended flow rate: 1 to 2 L/min at the nozzle
- Suitable for systems such as 100 psi, 5 L/min pumps commonly used for window cleaning
- Can also apply Bio Cleanze, although it provides less penetration than the 6.5 nozzle
15 nozzle
Faster coverage with larger pumps
The 15 nozzle supports higher-flow application where a larger softwash pump provides sufficient output.
- Best suited to higher-flow applications
- Recommended flow rate: up to 10 L/min at the nozzle
- Suitable for larger softwash pump systems
Understanding flow rates
Reducing the size of the nozzle opening increases pressure and velocity but reduces the volume of liquid flowing through the nozzle.
You can visualise this by squeezing the end of a garden hose. The water travels further, but the overall flow rate decreases.
Different chemicals and surfaces require different flow rates. Selecting the correct nozzle helps you apply the chemical efficiently while controlling overspray and run-off.
How to check your flow rate
Direct the nozzle into a bucket for one minute and measure the volume collected:
- 2 litres collected equals a flow rate of 2 L/min
- 5 litres collected equals a flow rate of 5 L/min
Adjust the pump flow until you can apply the chemical evenly without creating excessive run-off.
With experience, you will develop a feel for the correct flow rate for different chemicals and surfaces.
