3.1
Choosing a Suitable Location
Location impacts the nature and extent of external airflow disturbances, which may affect performance of the
cabinet when it is exposed to these disturbances.
When installing the cabinet, it should be located as far away as possible from sources of airflow disturbance and
in an orientation which optimally shields the airflow of the cabinet from all external airflow disturbances. Please
note that the cabinet should not be placed close to another cabinet.
Please follow these guidelines when choosing a suitable location for your cabinet:
•
The location must be far away from:
» Personnel traffic flows.
» Air vents (in and out).
» Doors and windows.
» Any other sources of disruptive air currents or air drafts.
•
If drafts or other disruptive air currents exceed the face velocity of the filter, the potential exists for
contaminated air to enter the work zone of the cabinet.
•
A minimum distance of 50 cm (20 in.) to the top of the ceiling is recommended for blower changing
purposes.
•
A clearance of 183 cm (6 ft) in front of the cabinet is strongly advised in order to maintain proper airflow.
•
Please permit adequate space for cleaning behind the cabinet.
