Abstract:
An oscillating diaphragm fan having a plurality of subunits which each have an oscillating diaphragm that is excited by a magnetic system in an actuator chamber, wherein the air pulsation generated by oscillating diaphragm is discharged outwardly, the actuator chambers of the subunits are connected via means for compensating pressure and are encapsulated outwardly, and the magnetic systems of the subunits are excited out of phase with each other.
