6.1.2 Powder Level Sensor
(continued)
Refer to the Dwyer Photohelic
®
Gauge/Switch Section in the Appendix of this
manual for more specific information on this unit.
NOTE:
The range of the control sensor has been pre-set at the ETI
factory and should not be touched or changed without
consulting ETI personnel.
6.1.3 Powder Feed Chamber
Powder replenishment is supplied on demand from the Coater Level Sensor and
Powder Pump via the Powder Feed Chamber, attached to the Coater Bed. A
mixture of powder and air enters the Powder Feed Chamber. Once in the
chamber, the powder settles to the bottom and falls into the Coater Bed, while
the air exits to the exhaust outlet.
6.1.4 Optional Conventional Fluid Bed
The Conventional Fluid Bed (C.F.B.) is a non-electrostatic fluidizing dipping
bed that mounts over the electrostatic fluidized bed. There is an operator control
switch to run the High voltage “OFF”, and allow the C.F.B. to be used. The
C.F.B. has 8 inch deep side walls which holds the powder in a lightly fluidized
condition for the dipping of a pre-heated part.
The C.F.B. option is intended for heavy powder build applications on a hot part.
NOTE: CARE MUST BE TAKEN DURING DIPPING APPLICATIONS
TO NEVER TOUCH THE POROUS PLATE LOCATED AT
THE BOTTOM OF THE FLUIDIZING BED WITH A HOT
PART OR IT WILL MELT.

COLLECTOR
The 500 CFM Collector Module uses a ¾ HP motor to drive the Exhaust Fan. The
Exhaust Fan pulls air from Powder Application Hood (Canopy) and into the (2)
Cartridge Filters. The air passes through the Cartridge Filters and is forced through
the Final Filter. The clean, powder free air is returned to the surroundings.
Excess powder (not adhering to the parts) is carried by the air flowing through the
Hood to the Cartridge Filters, where it collects on the outer surfaces. When activated
(by pressing the Filter Pulse Manual Valve pushbutton), the pulse valves force air
from the Pulse Valve Air Manifold through the Cartridge Filter in the opposite
direction of normal flow. The pulse airflow cleans accumulated powder from the
Cartridge Filter media. The powder falls to the bottom of the Collector Module and
into the storage container where it can be recovered and recycled or discarded.
