SMOKE CONTROL
Principle of Operation
The ClearAir
TM TM
Pollution Control Unit removes smoke particles by
electrostatic precipitation. The principle of operation of electrostatic
precipitation is actually quite basic. The electrostatic cell is made up
of a series of aluminum plates spaced approximately
1
/
4
” (6.35mm)
apart and the number of cells used is determined by the air volume
and the type of cooking equipment involved. Every other plate is
energized with 5000 volts of D.C. power and the alternating plates
are grounded. At the entry point of the cell is a series of thin wires
spaced approximately 4” (101.60mm) apart. These wires, referred
to as ionizing wires, are energized with 10,000 volts D.C. and as
the smoke particles enter the cell and pass over the wires they
receive a positive charge. As the charged particles continue through
the cell, the positive plate repels them and the negative or grounded
plate attracts them. Thus, the smoke particles are collected on the
negative plates. The action is efficient, safe and simple.
Wash Cycle
All Gaylord ClearAir
TM
units include, as standard equipment,
an internal washdown system and control cabinet which
when activated washes the unit with hot detergent injected
water to remove the daily accumulation of smoke and
grease particles. The washdown system and contols are
interfaced with the Gaylord Water Wash Ventilator. There
are two possible arrangements of controls for the opera-
tion of the Ventilator and the ClearAir
TM
Unit as illustrated
on page 9. In the first arrangement the Control Cabinet in
the kitchen serves both the Ventilator and the ClearAir
TM
Unit. The hot water solenoid valves and detergent pump
and container for both the Ventilator and ClearAir
TM
Unit are
located in this cabinet.In the second arrangement there is a
Control Cabinet for the ventilator electrically interfaced with
a Sub Panel that serves the ClearAir
TM
Unit. The hot water
solenoid valves and detergent pump for the ClearAir
TM
Unit
are housed in the Sub Panel and the detergent container
is located below or next to the panel. The detergent pump
and container for the Ventilator are both housed in the
main Control Cabinet located in the kitchen. In both ar-
rangements the Exhaust Fan, ESP, Wash Cycles and Fire
Cycle Functions are controlled by the Ventilator Control
Cabinet. The difference between the two is the location of
the plumbing components.
Fire Cycle
In the event of a fire, a 250
o
F. thermostat, mounted in the
airstream, will activate shutting off the exhaust fan and ESP
cells, and turning on the water sprays within the ClearAir
TM
Unit. The fire cycle of the water wash ventilator will also
activate at this time. The water will run continually until the
thermostat cools below 250
o
F, and then run for another
2 minutes. At the conclusion of this cool down cycle the
exhaust fan may be started by pushing "Start Fan".
