Fans for AC unit

Hello

I am in the process of choosing an fan for my split AC unit at the moment, and the customer wants to have an 30 Pa pressure drop between the inlet return air and the inlet supply air, and I am not completely sure about how I make sure this criteria is accomplished, could anybody give some good advice on how to choose the right fan ?

the airflow should minimum be 150 m^3/hr but higher is desirable :-)

You will have to look at the performance curve for a couple of different fans and find one that when the pressure differential is 30 Pa (sounds low if it is a ducted system) the airflow is above your desired 150 m3/hr.

:cool:
