Performance test

The performance test is carried out by measuring the pressure difference between the inlet and outlet of the fans. Subsequently, the pressure difference is used to read the airflow through the curve in the figure or to calculate the airflow using the equations respect to the type of air handling unit.

Before the measurement of the pressure difference is carried out it is important that:

There are new clean filters in the air handling unit

The air handling unit is operating at 100 % airflow and the control voltages are stabilised. Be aware, of that the stabilisation can take a few minutes

The air handling unit is not in any system condition such as Low Temp. process or Condensation process, because it influences the airflow.

AM/AMC 150 - generation 2 (9000100102/9040100102)

If you have an AM150 or AMC150 generation 2 where the fans have been replaced to a newer type, please use the data for generation 3 given below.
