PRODUCT DESCRIPTION
Application
The MS Topcoat A4 automatic powder gun is designed
exclusively for electrostatic coating with organic powders.
This powder gun is suitable for electrostatic coating of ob-
jects of all shapes and geometries, provided they can be
grounded. The Topcoat A4 Automatic receives power from
a controller which powers a cascade that generates a high
voltage DC charge to the electrode, creating an electrostatic
field between the nozzle and the target.
One of the many features of the MS Topcoat A4 Auto-
matic powder gun is that the electrical energy, which is
available from the resistive charging electrode, is limited
to the optimum level of safety and efficiency. The system
is incapable of releasing sufficient electrical or thermal
energy during normal operating conditions to cause ignition
of specific hazardous materials in their most easily ignited
concentrations in air.
As the applicator electrode approaches ground, appli-
cator circuitry causes the high voltage to approach zero
while the current approaches its maximum value. This
performance is validated by independent test agencies
that give ATEX EN 50 050 approvals.
Foreseeable misuse
• Coating of ungrounded objects
• Use of enamel powder
• Incorrect powder flow rates
• Incorrect electrode air flow values
• Using moist powder
