DESCRIPTION OF FUNCTION
Main compressed
air connection
The arrows always show the direction of flow
Figure 2
The fluidized powder in the powder hopper is sucked into the injector
by means of the conveying air (1- red hose). The powder/air mixture
reaches the powder gun through the powder hose (2). The powder is
electrostatically charged at the nozzle of the gun. In addition, an elec-
trostatic field is created between the gun nozzle and the grounded
object. The charged, and sprayed powder adheres to the surface of the
object.
The powder is fluidized by air forced through a porous plastic plate
from below. The powder acquires, thereby, fluid-like characteristics.
The conveying air, supplementary air, and rinsing air are set on the
control unit, and the fluidizing air is set on the fluidizing unit on the
trolley. The functioning of the injector is described in the EasyFlow
injector operating instructions.

2. Set the total air volume (For further information see the EasyFlow
Operating Instructions)
The total air volume is dependent on the powder hose length, the
number of turns of the hose, the hose diameter, and the object
to be coated.
The value set for the total air volume can be left as it is, as long
as the same powder hose is used. If the hose length and/or the
hose diameter are changed, then the total air volume must be
reset.
3. Select the powder output volume according to the desired
coating thickness.
The selection takes place with the aid of the Keys +and –either
