1.3.2 PCR-A
1.3.2.1 Airflow Velocity Test
Put the anemometer on a plane that is 150 mm (6 in.) from the filter face, and measure the airflow using the
grid below:
Cabinet Model
3 feet
4 feet
Width = w (mm) (in)
914 (36.6)
1219 (47.9)
Depth = h (mm) (in)
457 (17.9)
457 (17.9)
Left to
Right
Distance from walls = a (mm) (in)
150 (5.9)
150 (5.9)
Distance apart = x (mm) (in)
307 (12.1)
306 (12.1)
Front to
Back
Distance from walls = b (mm) (in)
150 (5.9)
150 (5.9)
Distance apart = y (mm) (in)
157 (6.2)
157 (6.2)
Average Velocity: m/s (fpm)
Maximum Deviation: m/s (fpm) = %
Acceptance: 0.275 – 0.325 m/s (55 – 65 fpm)
Deviation Acceptance: 20%
Result: Pass / Fail
Actual motor voltage for nominal airflow:
True RMS: VAC
Averaging: VAC
Note: From factory, both True RMS and Averaging motor voltage are given. If your voltmeter has
“True RMS” written on it, use the True RMS voltage given here, for new cabinet installation. If
“True RMS” is not written there, it’s an averaging meter, so use the Averaging Voltage
