Ventilator Description Overview
The Gaylord Model CG3-UVi-SPC Series is a 3 stage Ventilator containing a high efficiency Grease
Extractor, Ultraviolet Light (UV) and Electrostatic Smoke Pollution Control (SPC) in one integral unit
(Refer to Figure 1-3-1). Stage 1, the primary Grease Extractor, removes the larger grease particulate, key
to the efficient operation of the UV and Smoke Pollution Control sections. Stage 2 is an Ultraviolet Light
System that dramatically reduces grease accumulation in the Pollution Control section, exhaust plenum,
ductwork and exhaust fans. This section contains UV Modules each having six high efficiency lamps
powered by high tech solid state ballasts. Stage 3, the Smoke Pollution Control section, contains
electrostatic precipitator ESP Cells to remove smoke particulate for the airstream.
The Ventilator incorporates six wash manifolds that connect to the Wash Control Cabinet. The Wash
Control Cabinet contains the Command Center that controls the exhaust fan and Wash Cycles. The
primary grease extractor, UV and SPC sections are automatically washed with hot detergent injected
water each time the exhaust fan is shut off, washing the accumulated grease and smoke particles out of
the Ventilator and into the building drain system.
UV and SPC Safety
The Ventilator has many safety features to ensure operators are not exposed to UV light or to high
voltage from the ESP Cell high voltage transformers. The access doors into the Extraction Chamber, UV
Lamp Modules, and the ESP Cells are monitored so if any door is opened the UV Lamps and the ESP Cells
immediately go off. In addition a pressure switch monitors the exhaust flow to shut off the lamp if the
airflow is below a minimum level.
Approvals
The Ventilator is ETL listed to UL Standard 710, 710C and 867. In addition the Ventilator has been tested
for UV light omissions, in compliance with the ACGIH (American Conference of Governmental and
Industrial Hygienist) requirements for exposure to UV light. The Ventilator is also listed by ETL to NSF
Standard Number 2.
