AIR FLOW BALANCING

(CONT'D)

1

For this flow measuring station, cut

the duct and place the flow

measuring station between each

station. Make sure that the flow

measuring station’s air direction

arrow points in the direction of the

airflow. Secure the flow measuring

station with duct tape.

2

Before taking the reading, make sure

that the magnehelic gauge is level

and at 0. Refer to the flow

measuring station’s chart to

determine your unit’s airflow velocity.

3

Adjust the “Supply Air Out” damper

until you reach the desired velocity.

Follow the previous steps to adjust the

“Exhaust Air Out” damper, if needed.

• To avoid airflow

turbulence and incorrect
readings, the airflow
velocity should be
measured on steel
ducting a minimum of
18” (457 mm) from the
unit or elbow and before
any transition.
