Vacuum Pressure (Suction) & Static Pressure (Static Resistance) Why Important? If the vacuum pressure generated by the fan is not sufficient to overcome the static resistance of the ductwork and of the filters (called differential pressure or DP) several problems will arise. The system will suffer a loss of suction at the collec-
