GREASE EXTRACTION
The Gaylord Royal "RG" Series Ventilator extracts up to 95%
of the grease, dust and lint particles from the airstream passing
through it, when operated and maintained in accordance with
design specifications.
The hot, contaminant-laden air rising from the cooking surface
merges with the higher velocity air that wipes the front of the
cooking equipment and extends, like an air blanket, from the
front edge of the cooking equipment to the air inlet of the
ventilator. As the air moves through the ventilator at a high
speed, it is forced to make a series of turns around three
baffles. As the high velocity air turns around each baffle, the
heavier-than-air particles of grease, dust and lint are thrown out
of the airstream by centrifugal force. The extracted grease,
dust and lint are collected in the interior of the ventilator,
remaining out of the airstream until removed daily by the wash
cycle.
Baffle #1
This baffle is located at the air inlet of the ventilator and is
formed as part of the inspection door. There is a small grease
collecting gutter on the back side of the baffle which drains off
liquefied grease, preventing it from re-entraining into the
airstream.

Baffle #2
This baffle is on the interior back wall of the ventilator and
includes a square stainless steel pipe, equipped with brass
spray nozzles on 8" to 10" centers. During the wash cycle, hot
detergent water is released through the nozzles. If the
ventilator's automatic fire control system is activated, fire
smothering water spray is also released through the spray
nozzles.
Baffle #3
This baffle is located on the back of the inspection door.
NOTE: Some ventilators may be equipped with optional
"Custom Air" baffles (shown dotted) which reduces the ex-
haust volume where the baffles occur.
NOTE: Some ventilators may be equipped with optional
continuous cold water mist. Refer to Page 25 for details.
