FPJB Selection and Examples

Example 1:

Airflow given as 10,000 cfm – select louver size.

A. Determine louver free area by dividing airflow by free area
velocity (do not exceed 1250 fpm on intake louver application).

10,000 cfm ÷ 1250 fpm = 8.0 sq. ft.
Airflow F.A.V. Req’d Louver Free Area

B. Select a louver with at least the required louver free area from
the Free Area Chart above.

48”w x 54”h

8.81 ft. free area
1135 fpm free area velocity (10,000) cfm ÷ 8.81 sq. ft. F.A.V.
(Other selections available - see Free Area Chart above.)

Example 2:

Louver size given 42”w x 72”h intake - determine maximum
airflow.

A. Use Free Area Chart to determine.

Free Area = 10.28 sq. ft.

B. Free Area x Free Area Velocity (do not exceed 1250 fpm on
intake louver applications).

10.28 sq. ft. x 1250 fpm = 12,850 cfm
Free Area F.A.V. Max. Airflow
