NOZZLE SELECTION GUIDE
DETERMINING SPRAY TIP SIZE
As stated earlier the outlet pressure is
determined by ejecting a known volume of
water through a spray tip. The size of this tip is
an important factor of efficient pressure cleaner
performance. A tip that is too large may
produce insufficient pressure. A tip that is too
small may cause over high pressures causing
damage to the pump and other system
components.
Refer to the above chart to select the correct
nozzle size for your application.
Firstly, ascertain the output flow of your pump
from the technical data. Then find the
pressure (psi) you require and read down the
column until you reach the output closest to
your own pump. The correct spray tip for the
result you require must not exceed 90% of the
high flow.
Example: 2030 psi at 11 litres per minute,
calculate 90% of flow value = 035 nozzle.
Aussie Laser Tip Nozzles are available in
various sizes and spray angles. It is advisable
to keep a selection different sized and angled
spray tips handy for different cleaning
applications.
Nozzles are also available with an adjustable
spray angle (see Aussie >Vario-Zoom= nozzles
for domestic and commercial pressure
cleaners.
Big Berties are Bonza!
