then divided by 3.
Then, multiply the average speed value by an effective
area factor according to the filters size (refer to table
below).

For Imperial calculations, use air flow speed units in
feet per minute and use the effective area in square
foots (SQ.FT) to get an air flow in cubic foot per minute
(CFM).
For Metric calculations, use air slow speed units in
meters per hour and use the effective area in square
meters (SQ.M) to get an air flow in cubic meter per
hour. To convert a cubic meter per hour air flow into
liters per seconds, multiply the value by 0.278.
Air flow adjustment
If an exhaust hood air flow is too high or too low, adjust
the amount of rotation per minute of the wheel on the
exhaust fan.
•
Pulleys and belt adjustment;
•
Manual dimmer adjustment with provided
screw ;
•
Adjustment via inverter (variable frequency
drive) of the maximum frequency operation.
Some exhaust hood model may be equipped with a
manual damper located under the exhaust hood collar.
The air flow will adjust according the opening. The
manual damper is used to facilitate balancing of many
exhaust hoods on the same exhaust fan.
The Geo-Vary grease extractor can be used the same
way to facilitate the balancing of many exhaust hoods
on the same exhaust fan. The air flow will adjust
according to the opening of the Geo-Vary grease
extractor. If modifications are to be made to the
adjustment of the Geo-Vary filters according to new
balancing requirements, contact Cadexair to receive
new labels according the required adjustment.
Maintenance
Stainless Steel
Stainless steel is very resistant to corrosion but it is not
foolproof. It is necessary to clean frequently in order
to preserve the surface integrity. It is recommended to
clean the metal when it is dirty and to not wait until a
deep cleaning is necessary to keep the original
appearance.
A regular cleaning with a soap or soft detergent
followed by a hot water rinse usually provides good
results. Si the water used contain a high percentage
of minerals, it is recommended to dry the surface with
a soft cloth.
Commercial products with the mention
“suitable for
stainless steel” can and should be used. Some
commercial cleaning products containing phosphates,
synthetic detergents and alkali can be used to clean
severely stained or tarnished stainless steel. These
products ensure a cleaning without danger to the
surface and are effective. It is recommended to read
carefully the manufacturer’s instructions before using
a product.
IMPORTANT
Never use a chlorine based cleaning
product
or
by-product
such
as
hydrochloric acid (bleach, Lysol, etc.)
How to apply cleaning products
Cleaning products are applied directly on the surface
to clean or using a soft cloth or sponge. In both cases,
carefully rinse with clear hot water and wipe with a dry
and soft cloth or let the surface dry.
Always rub with the grain.
