50 Hz Piezoelectric Fan Kit

Please note that this fan requires bias voltage electronics, provided below, to be driven off of line power. Failure to do so will damage the device.

Piezoelectric fans are solid state devices without wearing parts. The oscillating FR4 blade is driven at resonance (50Hz in this case) by a piezo bending element. In free air, the high amplitude resonant vibration of the plastic blade causes the formation of a high-velocity flow stream. Maximum airflow occurs along the axis of the fan's centerline. Air intake is above and below the swept out volume of the blade. Its simple design lends itself to low cost in high volume production.

Drive Electronics

PIEZO.com fans can be connected to 240V line power with the DC Bias conditioning circuit. This circuit increases the voltage tolerance of the piezo by generating and applying a DC offset to the piezo fan, allowing it to run at a higher voltage. The schematic for the circuit is shown below.
