DYNAPRECIPITOR WATER WASH SPRAY BOOTHS
Global Finishing Solutions’ (GFS) Dynaprecipitor Water Wash Spray
Booth handles a larger variety of paints in a wider range of viscosities
and drying speeds, at higher production rates than any of the
conventional spray booths.
This booth employs two well-known engineering principles to remove
paint particles from exhaust air in painting operations. First, by drawing
air through a continuous curtain of moving water, suspended paint
particles are scrubbed out. Second, when air carrying paint particles
makes a sudden change in direction of flow, centrifugal force slings
the solid particles out of the air stream (called impingement). Entrained
paint particles are thrown against adjacent walls and curtains. Water
then flushes the particulate into the collecting pan. Through these two
actions the air reaching the exhaust stack is virtually free of airborne
particles keeping the stack area cleaner longer.
A
Upper Centrifugal
Wash Chamber:
Here, most of the paint
particles are separated
from the exhaust air. This
separation is accomplished
by centrifugal force on the
paint particles as the air
abruptly changes direction
of flow while simultaneously
being forced to pass through
powerful water sprays.

B
Lower Wash Chamber:
In the lower wash chamber,
the exhaust air must pass
through an unbroken curtain
of water. Again, water
scrubbing and centrifugal
force combine to remove
the remaining paint particles
before the air passes to the
exhaust chamber.

Recessed Drain:
The recessed drain supplied
insures complete removal of
water from the collecting
pan. This feature simplifies
the cleaning operation.
Standard Features
These booths are constructed of 18-gauge galvanized
panels for field assembly:
> An upper and lower wash chamber
> Large capacity collecting pan
>Slotted water intake pipe to ensure sediment
free water
>Circulating water to maintain a constantly
flushed system
> Removable manifold for easy maintenance
>Hinged water curtain to allow easy access to
the rear of the collecting pan
>Access door located just below the fan for
easy maintenance
> External float box with level control
Space Saver:
The booth saves floor space. Its short-depth wash
unit gives water-wash-spray-booth advantages while
occupying conventional booth space.
Easy Maintenance:
Hinged front water curtain permits easy skimming of
coagulated paint particles from collecting pan. Optional
automatic centrifugal separators are available.
Circulating System:
Circulating water forms a continuous, constantly
flushed system that has no sediment-accumulating
dead ends. Rate of water flow is quickly adjustable. An
automatic water level control supplies make-up water to
compensate for slight daily evaporation loss.
NOTE: Check with local codes
for disposal.
Dynaprecipitor® is a registered trademark of
GFS.
The wash water should be treated (compounded). This causes the
paint particles to coagulate and allows convenient skimming when
cleaning out the collection pan. GFS recommends that the end
user enlist the support of an experienced chemical supplier that
will provide the paint testing required to support the chemical
treatment for controlling the pH, foaming and detactifier agent to
enhance the performance of the water wash equipment.
Correctly engineered water wash spray booths provide an extremely
efficient means for removing paint particles from the exhausted air.
In addition, they are the most acceptable type of spray booth for all
health, fire, and building codes.

NO PUMP WATER WASH SPRAY BOOTHS
NO PUMP Spray Booths
Features:
Without benefit of pump or water-spraying manifold, GFS’ NO PUMP
SPRAY BOOTH uses the highly effective scrubbing action of a water
wash to separate paint particles from exhaust air. By ingenious
channeling of the paint-laden exhaust air through a “water tunnel” the
NO PUMP system eliminates pumps, piping, filters, manifolds, and
nozzles.
>12 and 14 gauge galvanized welded washer
assembly.
How It Works
Paint-laden air is drawn into the washing chamber at high velocity
through an opening between the entrainment plate and water surface.
The controlled dimension of this opening and the specially designed
profile of the entrainment plate force the high velocity air to become
severely turbulent, splash up water, and become thoroughly mixed with
the overspray.
> Standard panel work area enclosure, 18 gauge
galvanized.
>Automatic water level control for maintaining air
velocity through entrainment plate gap to within
+ 1%.
> Low sound, high efficiency mixed flow in line fan.
> Inside-accessible ETL-listed 4-tube light fixtures
(includes color corrected T-8 tubes).
> Wash chamber works equally well in both
“Crossdraft” and “Downdraft” booth configurations.
>Access door located on back wall for inspection
and fan maintenance.
> External float box with level control.

Water Tank
Next, this rapidly moving mixture of air, paint particles, and water
droplets strikes the distribution plate. The mixture is forced to change
direction abruptly and to flow upward through a series of baffles. The
“mixture” flow changes direction 11 times during its passage through
the baffle section. At each change centrifugal force separates air from
paint particles and from water droplets. The resulting rain of water,
particularly from the lower baffles, serves as an additional water
curtain for scrubbing the incoming spray laden air. All of the paint
spray that is separated from the air falls back into the water tank.
4
The water in the tank should be treated with the proper
compound to suit the material being sprayed in order that the
paint particles be made non-tacky and settle to the bottom of
the tank where they agglomerate as a soft, foamy residue.
Residue buildup may approach to within 2 inches of the water
surface without adversely affecting the “NO PUMP” action in
the water tunnel. Residue removal is very infrequent, even
in high production painting. Optional automatic centrifugal
separators are available.
The gap between the water surface and entrainment plate is
kept with + 1% of its optimum dimension. This is accomplished
with a GFS Float Box with Water Level Control Unit. This unit is
located outside the booth proper - isolated from contaminating
water and spray.
Yet it is directly connected hydraulically to the water tank and
senses water level changes immediately and accurately. Its
external location gives it maximum accessibility for inspection
and calibration.
Easy Assembly
NO PUMP washer is shipped in 3 major all-welded sections
for ease of field assembly: Pan, Wash Chamber, and Booth
Adapter (Closure Panels).
