OPERATION
The Gaylord “GX” Series Non Water-Wash Ventilator offers simplicity, economy and performance that
no other ventilator can offer. The unique “extractor
insert” gives a grease extraction efficiency far superior to that of a typical mesh or extractor filter.
The Gaylord “GX” Series Ventilators are UL Listed
and meet all the requirements of NFPA #96.
FAN OPERA TION
To operate the exhaust fan, push the “start” or
“stop” button on the Gaylord exhaust fan switch.
GREASE EXTRACTION
The Gaylord “GX” Series Ventilator extracts 90%
of the grease, dust, and lint particles from the airstream passing through it. Grease extraction is
accomplished by a unique, removable stainless steel
“extractor insert” which incorporates a series of
horizontal baffles. As the air moves through the
ventilator at high speed, it is forced to make a
series of turns around these baffles, forcing the
heavier-than-air particles of grease, dust, and lint
to be thrown out of the airstream by centrifugal
force. The liquefied grease then drains off into a
grease cup. The extractor inserts are available in
two sizes: 151/2" (5 3/4 lbs.) and 191/2" (6 3/4 lbs.).
IMPORTANT NOTE: Never operated ventilator
without extractor inserts in place.
CLEANING
At the end of the cooking day, or at periodic inter-
vals, the inserts are removed and can be washed
either in a dishwasher or soaked and rinsed off. To
ease in the removal of the extractor inserts, an
“Extractor Removcal Tool” is available which
eliminates the need for kitchen personnel to climb
up on the cooking equipment.

FIRE PROTECTION
NFPA #96 requires the use of surface, duct and
plenum protection on all non water-wash hoods. It
is these systems that are the first line of defense
against equipment fires. If the surface system fails
to extinguish the fire, the ventilator's internal fire
protection system then acts as a back-up.
This is accomplished by a spring loaded fire damper
which is activated by a 280° F fusible link or ther-
mostat located at the duct collar. In the event of a
fire, should the detection device reach 280° F, the
damper would close preventing the flames from
entering the duckwork and spreading to other parts
of the building. The fire is contained in the kitchen
area where it can be properly fought.
Surface, duct collar and plenum fire protection uti-
lizing The Gaylord Quencher System or other fire
protection systems currently on the market can be
factory installed as an option.
