7.1 Note on fan output and static pressure
•
The CFM rate stated on the fan and in the tables below is a
“nominal” airflow rate and is applicable only when no additional
equipment is attached to the fan.
•
When you attach any equipment to the fan (ducts, vent caps,
filters, splitters, elbows, etc.) you are introducing static pressure,
an obstacle in the path of the airflow. This will cause the final
amount of airflow delivered by the fan to be lower than the
nominal airflow.
•
Each duct fan has a maximum pressure rating which equals to
the maximum static pressure it can counteract in order to move
a certain volume of air.
•
A pressure drop is the amount of static pressure introduced by a
filter or any equipment attached to the fan.

5. Fan maintenance
•
Use a damp cloth to remove dust and any debris build
up from fan components every 6-12 months
•
To avoid mechanical damage, do not apply pressure to
the fan blades.
