The motor connects with and drives the first impeller to rotate. The base is disposed in the frame and supports the motor. The noise silencer is located adjacent to the flow channel. The noise silencer includes at least one hollow chamber, and the hollow chamber has at least one hole communicating with the flow channel.

A ventilator includes a base, a drive device disposed on the base, an impeller coupled to the drive device and driven by the drive device, and a cover assembled with the base to define a closed area between the cover and the base for receiving a first circuit board therein, wherein when an AC power source is input to the first circuit board to be converted, a DC power source is output to drive the drive device.
