Example for Perforated Face Supply

1.Hood set up

If the make-up air unit has a temperature control, it should be used to keep the supply air at the desired room discharge air temperature.

2.Measure Velocities

Divide the perforated face panel into a grid of equal areas, each approximately 4 in. (100 mm) square.

Measure the velocity at the center of each grid area. A digital 2.75 in. (70 mm) rotating vane anemometer or equivalent is suggested. The center of the anemometer should be held tight to the face of the panel, and parallel to the filter. Both squareness and distance are important for accuracy. Calculate the average velocity of the panel.

3.Measure the length, height, and width of the perforated face panel.

4.Calculate the perforated face panel volume in CFM by using the following formula:

5.Calculate the system’s volume by repeating the process for the remaining panels and adding the individual panel volumes together.
