Application Area
Product Description
Air jet nozzles are particularly well suited for the quick
and safe ventilation of closed rooms, containers, tank
system, sewer tunnels, and pipelines. The mobile unit
can be utilised for the quick and safe ventilation that
requires a steady supply of fresh air and continuous
dilution and discharge of noxious gases and vapours.
Compressed air is used to operate the powerful and jet
nozzles. They can be used to blow in air as well as
extracting air during the ventilation. The nozzles are built
into a tube and connected to a plastic plastic air duct, or
alternatively inserted into a tripod.

Model selection
In jet nozzles are compact devices that are easy to
install. They are operated with compressed air.
The compressed air enters the
specially designed ring-shaped
distribution head through a radial
connection, leaving it through an
annular gap at high velocity. In
doing so, the ambient air is swept
along. Depending on the width of
the system, the generated airflow
is up to 80 times of the supplied
compressed air. A steady supply of fresh air and
the continuous dilution and
discharge of noxious gases and
vapours are possible.

Extracting light-weight materials.
Air jet nozzles can be used selectively to extract
light-weight materials such as chips, fabric,
threads, lint, and dust.
Generating spray mist
When installing a fluid supply line upstream in the
intake area, spray mist can be generated in the
blow-out section.
Extinguishing equipment
High level of extinguishing effect due to the elevated cooling potential of the finely distributed water.
Drying surfaces
During cleaning and coating processes of surfaces,
the use of air jet nozzles can reduce the drying
time considerably.
