MODEL “GX2-BDL-DS”
NON WATER-WASH VENTILATOR
GENERAL SPECIFICATIONS
Furnish Gaylord Ventilator Model “GX2-BDL-DS____________” as shown
on plans and in accordance with the following specifications:
GENERAL: Each ventilator shall have one high-velocity centrifugal
grease extractor with two air inlet slots, one on each side of the extractor.
One slot shall have an adjustable baffle to regulate the ratio of exhaust
volume between the two slots. Each ventilator shall contain one or more
removable “extractor inserts” with a grease extraction efficiency of 90%
when operated at design specifications. Extractor inserts shall be
constructed of stainless steel and contain full-length, self-draining baffles.
Extractors shall be easily removable, for periodic cleaning, from the floor
area immediately in front of the equipment by utilizing an extractor removal
tool. The grease collecting gutter at the bottom of the extractor housing
shall slope to a drain at one end of the ventilator to a removable stainless
steel grease cup. The sloped gutter shall be concealed by an apron which
extends the full length of the hood. Continuous brackets shall be provided
to facilitate hanging from the overhead structure.
ventilator shall include “Custom Air” baffles to reduce the exhaust volume
over specific cooking equipment as indicated on the plans (add suffix “CA”
to model number). The ventilator shall operate at air quantities and static
pressure as indicated on plans.
❏ ❏
❏ Ventilator with a Fire Damper (standard equipment) - The
❏ ❏
ventilator shall be equipped with a full length fire damper located in the
ventilator extractor plenum between the extractor inserts and the ventilator duct collar.
❏ ❏
❏ Thermostatically Operated Fire Damper (standard) - The damper
❏ ❏
shall be controlled by an electrically driven actuator, specifically listed for
such use and shall be activated by fail safe thermostat(s) located at the
duct collar. Upon activation, the exhaust and supply fan shall shut off and
the damper shall close, in the direction of air flow, sealing against the front
of the plenum and act as a fire barrier to prevent flame from entering the
plenum and duct system. The damper shall also close each time the
exhaust fan is turned off, to prevent conditioned air from escaping the
occupied space via thermal drafts, and then re-open when the exhaust
fan is started. Fire dampers located at the exhaust duct collar are not
acceptable. The ventilator shall be UL Listed under the category “Exhaust
Hood with Exhaust Damper”. Access doors to reach duct fire protection
nozzles shall not be permitted.
❏ ❏
❏ Fuse Link Activated Fire Damper (optional) - (series prefix “GX2-
❏ ❏
FLD”) The damper shall be spring loaded and activated by fuse link(s)
located at the duct collar. Upon activation, the exhaust and supply fan shall
shut off and the damper shall close, in the direction of air flow, sealing
against the front of the plenum and act as a fire barrier to prevent flame
from entering the plenum and duct system. The damper shall be manually
reset without the use of tools and without opening or removing access
panels. Dampers located at the exhaust duct collar are not acceptable.
The ventilator shall be UL listed under the category “Exhaust Hood with
Exhaust Damper”.
❏ ❏
❏ Ventilator without Fire Damper (optional) - (series prefix “GX2-
❏ ❏
ND”) - The ventilator shall be UL listed under the category “Exhaust Hood
without Exhaust Damper”.
CONSTRUCTION: The ventilator shall be of all stainless steel construction, not less than 18 gauge, type 304. All exposed surfaces shall be a
number 4 finish. The use of aluminized steel, galvanized steel, or 430
stainless steel is not acceptable in any part of the ventilator.
ELECTRICAL: The ventilator shall be factory pre-wired to a single
connection point. Ventilators built in multiple sections shall be furnished
with coiled flex conduit for interconnecting sections by applicable trades.
LIGHT FIXTURES: The ventilator shall be equipped with ❏ 100 watt
surface mounted incandescent, ❏ 150 watt recessed incandescent, ❏
recessed fluorescent, light fixtures. Light fixtures shall be factory prewired
to a single connection point. Ventilators built in multiple sections shall be
furnished with coiled flex conduit for interconnecting sections.
ACCEPTANCE & APPROVALS: The ventilator shall be UL and NSF
listed. The ventilator shall comply with all requirements of NFPA-96, IMC,
UMC, BOCA and SBCCI model codes.

APPLICATION
Used for typical island style cooking arrangements where light or
medium duty equipment is used on one side and light-duty equipment
on the other, and the distance between the equipment does not exceed
30". Consult factory for exceptions. Refer to the Master Engineering
Data Sheet in the Gaylord catalog for determining light and medium
equipment.
FEATURES
• Fire Damper Within Ventilator Plenum
• All Type 304 Stainless Steel
• 90% Grease Extraction Efficiency
• CUL and NSF Listed
• Complies With The IMC, UMC, BOCA and
SBCCI Mechanical Codes
• Fail Safe Damper Control Switch
DESCRIPTION
The Gaylord Model “GX2” Series Ventilator has been tested to UL
Standard 710 and is UL Listed under the category “Exhaust Hood with
Exhaust Damper”. The ventilator extracts up to 90% of the grease
by centrifugal force when operated and maintained in accordance with
design specifications. Centrifugal grease extraction is accomplished
by unique, removable stainless steel “extractor inserts” that incorporate a series of horizontal baffles. At the end of the cooking day or at
periodic intervals, the inserts are removed and can be washed either
in a dishwasher or soaked and rinsed off. An extractor removal tool
is available which makes removal of the extractors extremely easy.
The extractor inserts come in two sizes: 15½" (5¼ lbs.) and 19½"(6¾
lbs.). The GX2 series is equipped with a thermostatically activated, or
optional fuse link activated, internally mounted fire damper. The
ventilator is also available without a fire damper, identified by the prefix
“GX2-ND”. The GX2 series can be totally integrated with the “CG3”
water-wash series.

Mechanical Requirements
Exhaust volume depends upon the type of cooking equipment and the type
and volume of cooking. Refer to the Master Engineering Data Sheet in the
Engineering Data section of the Gaylord catalog for the charts to determine
exhaust volume, duct sizes, and static pressure. The standard “GX2-BDLDS” ventilator operates at 250 CFM/Lin.ft. on the medium side and 150
CFM.Lin.ft. on the light side for a total of 400 CFM/Lin.ft. If the cooking
equipment requires more exhaust, as determined by the Master Engineering
Data Sheet, it may be necessary to use back-to-back ventilators, model
“GX2-BDL-BB” series (consult factory).
The manufacturer reserves the right to
modify the materials and specifications
resulting from a continuing program of
product improvement or the availability of
new materials
