As with all spray nozzles there is often a
bewildering array of products on the market with different flow rates,
spray angles and design types. Often expert advice will be required to
make the final selection but prior to calling an expert supplier its is
best to consider the following
Black Nozzle: Uses a wider spray and lower PSI for soap application.
zjautoparts offers several nozzles for use with your pressure washer, giving you a choice of spray angles and pressures that work best for your cleaning task.
Degrees of washing:
0° Red Nozzle: Used for blasting hard to clean items such as caked mud, tar, glue, stubborn stains and much more.
15° Yellow Nozzle: Used for paint preparation, removing dirt from construction or farm equipment, removing growth from boats and marine equipment, etc.
25° Green Nozzle: Used for standard cleaning/washing to remove general mud, dirt and grime from surfaces.
40° White Nozzle: Used for light cleaning and rinsing of automobiles, boats, roofs, windows etc.
Nozzle selection
Are there any constraints on the materials of construction?
Nozzles can be made in many different materials but not all types can be made from all materials. So, for example, if spraying at high temperatures plastic nozzles may not be suitable.
What flow rate is required?
The nozzle supplier you select will need to understand how much fluid you are looking to deliver per minute in order to select a suitable nozzle. If flow rates are very low then this may necessitate the use of air atomising nozzles which means as compressed air supply will be required in the system.
Are there any space constraints?
A flat fan need space to spread out. If there is very limited space between the feed pipe and the target then this may necessitate wide angle spraying or deflection type nozzles.
Is the environment cause blockages?
This may well affect the choice of nozzle. Elliptical orifice nozzle are cheap and easy to maintain but they are the most prone to clog and block. It may be a false economy to go with the basic option if clogging is likely. A good nozzle supplier will be able to advise accordingly.
How viscous is the fluid?
The spray angles and atomisation statistics given in nozzle brochures will be for spraying water. For more viscous fluids the angles produced will generally be lower and so may need to be compensated for. A quality nozzle supplier will have software that will calculate this difference but they will need to know the specific gravity and viscosity of the fluid in order to make the calculations for you.
Ask the experts
There are many flat fan nozzles on the market so if there is any uncertainty it's probably best to consult with a quality manufacturer. As the spray nozzle business is fairly niche it is likely that a good supplier will be able to deal in small quantities so buying directly from the manufacturer in quantities of 1's or 2's is not uncommon.
