The invention relates to an air pulser (1) for a motor vehicle, designed to be powered by a first voltage (U1) and a second voltage (U2), according to which the air pulser (1) comprises: a first interface (I48) for connecting to a power supply network (G48) supplying the second voltage (U2); a second interface (ILW) for connecting to a communication bus (BLW); a functional module (11) connected to the first connection interface (I48); a main switch (Q2) connected to the functional module (11), designed to enable signals (DAT) to travel through the communication bus (BLW); and a first protection module (10) for isolating the communication bus (BLW) from the power supply network (G48) when there is an overvoltage (USS) between the functional module (11) and the second connection interface (ILW).
