Fan Performance (P-Q) Test

Measures the relationship between the static pressure (P) and air flow rate (Q) of a fan or blower, based on the AMCA 210 Standard. A LongWin LW-9185 wind tunnel is used for this test.

Test Modes:

• Constant Voltage

Applicable on AC or DC powered fans.



• Constant RPM

Regulated by DC voltage or PWM.



• PWM Control

At a constant DC voltage, alter the frequency or duty %.



• The Operation Point (OP)
