Exhaust Hood
with Modular Grease Extractors
Model CA-S-M
Construction
All stainless steel construction, 1.09 mm,
(18 MSG) thick, type 304 with no. 4 finish
on all exposed surfaces. Each section
of the exhaust hood is equipped with
mounting tabs. The bio manifold is made
of copper pipe and the spray nozzles are
made of brass.
Lighting
A fluorescent or incandescent lighting
system can be installed inside the exhaust
hood at the plant when the unit is
assembled. These units are CSA
approved for use in kitchen exhaust hood.
Exhaust
The quantity of air exhausted depends
upon the type of cooking equipment
installed under the exhaust hood. When
heated by the cooking surfaces smoke and
grease laden air rise towards the exhaust
hood. (See Thermal Currents Chart).
Exhaust Ducts
All exhaust ducts are installed according
to NFPA 96. Horizontal ducts must be
sloped towards the exhaust duct collar to
avoid any liquid accumulation.
Fire Suppresion System
According to the National Building Code
(NFPA 96), the use of this type of exhaust
hood requires a fire suppression system to
protect the exhaust ducts and cooking
equipment. The system is activated by
fusable links or thermal detectors located
inside the exhaust hood. In case of fire, air
exhaust is maintained but make-up
air supply is interrupted. The grease
extractors are sprayed with water while
the ductwork and all cooking surfaces are
sprayed with a chemical product. Gas and
electricity to the cooking equipment and
lighting located under the hood are
interrupted and an alarm rings.
Application
This exhaust hood, suspended from the
ceiling, is designed to capture, clean and
evacuate hot air, smoke and grease
vapours produced by cooking surfaces. Its
effectiveness ensures the safety, health,
comfort and productivity of kitchen staff.
6
The exhaust hood is installed two metres
(six feet, six inches) above the floor and
overhangs cooking units by approximately
300 mm (12 inches).
Operation
Hot air, smoke and grease vapours from
cooking surfaces rise towards the exhaust
hood above. The GEO-VARY modular
grease extractors, installed in the unit,
filter and purify the air before it is
exhausted. The GEO-VARY baffle allows
the air flow to be field adjusted over each
appliance without affecting the overall
efficiency of the exhaust hood. Even after
the kitchen has been completely installed,
appliances can be relocated, added, or
removed from under the exhaust hood. A
simple adjustment will fine tune the
exhaust hood to provide excellent smoke
capture with maximum grease extraction.
The GEO-VARY process minimizes
exhausted air, resulting in substantial
savings in the capital investment and
operational costs required to evacuate and
make up air in the kitchen.

Description
CADEXAIR, model CA-S-M. The exhaust hood is equipped with
modular grease extractors. The GEO-VARY baffle allows the
exhaust air to be field adjusted over each appliance without
affecting the overall efficiency of the exhaust hood. The exhaust
hood is approved by ULC and built according to NFPA 96.
Construction
The housing of the exhaust hood is made of # 304 stainless
steel 1.09 mm (18MSG) with # 4 finish on apparent surfaces. All
welded joints are polished to the original finish. Each section of
the exhaust hood is equipped with mounting tabs.
Work by Ventilation Contractor
Connect exhaust duct collar, located on the top of the exhaust
hood, to the exhaust system. All exhaust ductwork must be
installed according to NFPA 96 and be sloped towards the
exhaust hood duct collar to avoid any liquid accumulation.
Work by Electrical Contractor
Supply and install lighting wiring to junction box on top of the
exhaust hood.
Skirting
The space between the top of the exhaust hood and the ceiling
is closed in with stainless steel panels with the same finish as
the exhaust hood.

Make Up Air
An air supply housing, made of insulated

the exhaust hood. The replacement air is
diffused and directed towards the ceiling
with the use of stainless steel grills built
into the housing. This low-projection
feature limits air movement to the zone
surrounding the cooking equipment.

Model CA-W-M
Construction
All stainless steel construction, 1.09 mm,
(18 MSG) thick, type 304 with no. 4 finish
on all exposed surfaces. Each section
of the exhaust hood is equipped with
mounting tabs. The bio manifold is made
of copper pipe and the spray nozzles are

Lighting
A fluorescent or incandescent lighting
system can be installed inside the exhaust
hood at the plant when the unit is
assembled. These units are CSA approved
for use in kitchen exhaust hood.
Exhaust
The quantity of air exhausted by an
exhaust hood depends upon the type of
cooking equipment installed under the
exhaust hood. When heated by cooking
surfaces, smoke and grease laden air rise
towards the exhaust hood. (See the
Thermal Currents Chart).
Exhaust Ducts
All exhaust ducts are installed according
to NFPA 96. Horizontal ducts must be
sloped towards the exhaust duct collar to
The exhaust hood is installed two metres
avoid any liquid accumulation.

Description
CADEXAIR, model CA-W-M. The exhaust hood is equipped with
modular grease extractors. The GEO-VARY baffle allows the
exhaust air to be field adjusted over each appliance without
affecting the overall efficiency of the exhaust hood. The exhaust
hood is approved by ULC and built according to NFPA 96.
Construction
The housing of the exhaust hood is made of # 304 stainless steel
1.09 mm (18 MSG) with # 4 finish on apparent surfaces. All
welded joints are polished to the original finish. Each section of
the exhaust hood is equipped with mounting tabs.
Work by Ventilation Contractor
Connect exhaust duct collar, located on the top of the exhaust
hood, to the exhaust duct system. All exhaust ductwork must
be installed according to NFPA 96 and be sloped towards the
exhaust hood duct collar to avoid any liquid accumulation.
Work by Electrical Contractor
Supply and install lighting wiring to junction box on top of the
exhaust hood.
Skirting
The space between the top of the exhaust hood and the ceiling
is enclosed by stainless steel panels with the same finish as the
exhaust hood.

Exhaust Hood
with Modular Grease Extractors
Model CA-W-M-PE
Construction
All stainless steel construction, 1.09 mm,
(18 MSG) thick, type 304 with no. 4 finish
on all exposed surfaces. Each section of
the exhaust hood is equipped with
mounting tabs. The bio manifold is made
of copper pipe and the spray nozzles are
made of brass.
Lighting
A fluorescent or incandescent lighting
system can be installed inside the exhaust
hood at the plant when the unit is
assembled. These units are CSA
approved for use in kitchen ventilators.
Exhaust
The quantity of air exhausted by a exhaust
hood depends upon the type of cooking
equipment installed under the exhaust
hood. When heated by the cooking
surfaces, smoke and grease laden air rise
towards the exhaust ventilator. (See
Thermal Currents Chart).
Exhaust ducts
All exhaust ducts are installed according
to NFPA 96. Horizontal ducts must be
sloped towards the exhaust duct collar to
avoid any liquid accumulation.
Make Up Air
An air supply housing, made of insulated
stainless steel is secured to the front of
the exhaust hood. The replacement air is
diffused and directed towards the ceiling
with the use of stainless steel grills built
into the housing. This low-projection
feature limits air movement to the zone
surrounding the cooking equipment.
Application
This exhaust hood, suspended from the
ceiling, is designed to capture, clean and
evacuate hot air, smoke and grease
vapours produced by cooking surfaces. Its
effectiveness ensures the safety, health,
comfort and productivity of kitchen staff.
The exhaust hood is installed two metres

The GEO-VARY process minimizes

savings in the capital investment and
operational costs required to evacuate
and make up air in the kitchen.
