Problem

Cause

Solution

Fluid density lower than the inten-
ded value

Check the fluid density value

Air flow greater than the intended
value

Check the resistance pressure
value of the system

Instability of air flow

Check the operating field envis-
aged by the operating curve

Fluctuations in flow due to other
fans operating in parallel

Check for correct installation on
the system

Pulsating operation

Intake air turbulence created by
system near intake opening

Check minimum installation dis-
tances.
