Description
The METACAP Spray Gun is a low pressure device.
The spray material is atomized with low pressure while at the same time
being encapsulated by a large volume of air; this air jacket presses the
atomized spray material against the surface to be processed and prevents
clouds of atomized spray material from escaping. This process is, however,
only efficient within a distance of max. 20 cm for a wide spray beam and of
approx. 30 cm for a circular spray beam. Please keep these distances during
the spraying procedures and always guide the spray gun in such a way that
the spray beam will vertically hit the surface. Otherwise, clouds of atomized
spray material will escape.
The nozzle and needle are made of stainless special steel and therefore
ensure a high durability. Both components are appropriate for various
coating materials.
This spray gun is equipped with the standard METACAP-AKKORD nozzle
set. This nozzle set is continuously adjustable according to nozzle sizes
between 0.5 and 3.6 mm. Thus, different coating materials can be processed
using only one nozzle set avoiding the annoying nozzle change and the
purchase of further nozzle sets. Furthermore, the AKKORD needle is a pipe
through which an additional atomizing airflow is brought to the coating
material to improve the spraying process.
Apart from the AKKORD nozzle set and nozzle cap, also nozzle sets with
fixed nozzle diameters and standard nozzle caps can be installed in the
spray gun.
For special applications, there are of course nozzle sets with fixed diameters
available upon request.
Important note:
The standard type of this spray gun can only be used to a certain degree in
case of highly corrosive or abrasive coating materials.
If the spray gun is charged with such materials, an increased need of
maintenance and cleaning and of spare parts will be the consequence.
If you are in doubt concerning the possible use of any kind of material with
this spray gun, please contact the manufacturer and exactly indicate the
material to be used and/or send us a sample.
Special designs concerning the whole material guiding system made of
special steel are of course possible. A list of the materials used for the
manufacturing of this spray gun is available upon request.
If necessary, please also check the other components of your coating
device, if they are suitable for the above mentioned coating materials.
