Design and Function
The AUTOSPRAY 481, Type APL 1.2, consists of a self-contained stainless steel cabinet assembly which is easy to clean and also provides excellent resistance to high humidity.
Because both the switch gear cabinet containing the pneumatic/electric control elements and electric wiring and the motor compartment have a pressurized enclosure, the Model 481 spray applicator for test panels is explosion-proof.
The explosion protection is certified by TÜV Rheinland (German technical surveillance association).
The AUTOSPRAY APL 1.2 is therefore suitable for use in potentially explosive atmospheres. If required, further components can be easily integrated into the pressurized switch-cabinet, without adversely affecting the explosion-proof properties of the AUTOSPRAY 481.
Since all connections are of the plug-in type, transportation for maintenance purposes is simplified and the spray booth can remain in operation.
The control unit not only allows the use of fixedprogrammed spraying parameters such as step sizes, horizontal and vertical stroke speeds, number of spraying strokes and exhaust air times; by altering the settings it is possible to adapt to practically all conceivable requirements of coating technology (e.g. applying a paint wedge). As a result, reproducible coating structures can be generated at any time.
The assymetrical layout of the operating panel ensures easy access to the test pieces which have been or are to be been coated, even in smaller spray stands.
The AUTOSPRAY 481 is pre-fitted to enable the use of one or two automatic flow cup spray guns which can be individually pre-selected.
Because there is no screen involved, a uniform air flow in the stand can circulate around the sprayers.
Airless guns can also be integrated as an option.
The gun holder is designed in such a way that the height and angle of the sprayer position can be readjusted.
The spray gun operates at an angle of 90° to the test panel. The machine can be supplied complete with spray gun on request.
The adjustable test panel holder makes it possible to vary the distance between the spray gun and the testing surface.
Changing the test panel holders is a simple matter – and the use of either magnetic fixing devices (secure, rotatable, with flow edge) or suction cups is possible.
