1. A fan or ventilator, comprising:
a motor,
wherein the motor includes:
a control unit with integrated motor electronics;
at least one sensor unit for pressure control or volume flow control;
at least one internal pressure hose inside the motor; and
a passage,
wherein:
the at least one sensor unit is modular;
the at least one sensor unit is configured to be plugged into or onto a printed circuit board of the integrated motor electronics such that the at least one sensor unit is in contact with the printed circuit board of the integrated motor electronics;
the at least one sensor unit includes a pressure sensor;
the pressure sensor is configured to determine: (i) a local pressure via the at least one internal pressure hose or at least one external pressure hose outside the motor; or (ii) a pressure difference between a pressure at a first location in the at least one internal pressure hose or the at least one external pressure hose and a pressure at a second location in the at least one internal pressure hose or the at least one external pressure hose;
the pressure sensor is configured to feed a signal corresponding to the local pressure or the pressure difference to a processing unit; and
the at least one internal pressure hose extends from the at least one sensor unit to the passage and from the passage to at least one connection for the at least one external pressure hose.
