Principle of Operation Overview

The Gaylord Model CG3-UVi-SPC Series Ventilator is a high grease extraction efficiency Ventilator that
includes the additional feature of an Ultraviolet Light System that dramatically reduces grease
accumulation in the exhaust plenum, ductwork and exhaust fans, and includes a Smoke Pollution Control
system that will reduce smoke opacity levels below 20% (Refer to Page 2-5 for information on opacity
levels). The Ventilator incorporates a hot water Wash Cycle that automatically washes the accumulated
grease and smoke particles out of the Ventilator and into the building drain system. The standard CG3-
UVi-SPC Ventilator has a full length fire damper located at the air inlet slot, two models have a fire
damper in the exhaust duct collar and one model does not have a fire damper. Refer to Pages 1-6 and 1-
7 for an explanation on fire damper options.
The operation of the exhaust fan and the Wash Cycle is controlled by the Gaylord Command Center
which is located on the face of the Wash Control Cabinet (Refer to Figure 2-1-2). All the plumbing
components, detergent pump and detergent tank are located inside the Wash Control Cabinet (Refer to
Figure 2-1-2 and Figure 2-11-2).
