NOZZLES AND NOZZLE HOLDERS
Airblast high-velocity venturi style nozzles have been designed specifically
to give maximum blast cleaning rates,
uniform
abrasive distribution and economy over an extensive operating life.
All
Airblast nozzles including the long life, 1¼" wide throat nozzles
incorporate the industry standard 50 mm coarse thread
giving quick release
from the nozzle holder and avoiding
grit
entrapment.
We still offer as an
alternative the original style fine thread nozzle.
TUNGSTEN CARBIDE NOZZLES
Airblast’s own brand wide range of Tungsten-Carbide lined nozzles are
available in both long venturi and
straight nozzle format. They constitute
the work horse nozzle of the industry being robust and efficient.
Airblast offers a full range of short straight and venturi nozzles for small
diameter hoses used in
cabinets or portables.
Internal diameters of
⅛"
to ½" ensure that you have the nozzle to suit your particular application.
SILICON
NITRIDE
/ CARBIDE NOZZLES
Airblast after much research and development in their continued striving for
improvement, have introduced the silicon
nitride nozzle with a polyurethane
jacket using a bonding technique to eliminate separation.
The jacket absorbs shocks ensuring no damage
to the liner of the nozzle takes place.
Moulding of the polyurethane is carried
out by vacuum which guarantees
the large 50 mm thread an accurate fit in the nozzle holder.
Field tests have shown an increase in nozzle life when compared with
equivalent sizes of tungsten carbide lined nozzles if handled
in the correct
manner, reducing operator fatigue and increasing productivity.
BORON CARBIDE NOZZLES
These offer the longest wear life of any nozzle material including
silicon
carbide, silicon nitride and tungsten carbide.
Peak nozzle production
performance is
able to be maintained for much longer periods
giving more
economic use of air and
abrasive.
NOZZLE HOLDERS
The
Airblast nozzle holders are available in nylon and aluminium.
All types are complete with high wear, replaceable rubber gaskets.
All nozzle holders are manufactured to fit externally over the
blast hose.
Internal grip rings bite into the
blast hose
for a safe and secure
fit and retaining screws provide additional holding power
without penetrating the
inner hose layer.
