INSTALLATION AND ADJUSTEMENT OF GEO-VARY FILTERS
Before starting up the hood, the filters need to be installed. Begin by inserting the top of the filters
into the slot located at the top of the hood and then placing the base of the filters in the grease
collection gutter.
Geo-Vary filters have a predetermined location and specific
adjustment. The Geo-Vary identification must always be on
the front. Make adjustments according to the instructions on
the label inside each hood (see Appendix 3).
AIRFLOW BALANCING
For hoods with baffle filters, turn on the exhaust fan and check the rotational direction before
balancing the system. Make sure that all the filters are in place and have on hand the flow rates
required to operate the hood correctly.
Cadexair recommends the following method,
based on measurements taken using a propeller
anemometer with a 2.75" (70 mm) wheel. Take 5
velocity readings in the filter slots as shown in the
image below. Measurements should be taken
perpendicular to the top of the filters at a distance
of approximately 2" (50 mm).
Calculate the average velocity per filter by adding
together the 5 mean velocity values and dividing
by 5.
Then, multiply the average velocity obtained by the effective area factor according to the filter’s
size:
