Description: The Low Voltage Piezo Fan Blade consists of a compound piezo / stainless steel blade element which has been wired and mounted on a PCB. It is a solid state device designed to to be used where only low voltage (up to ±15 Vp) is available. The fan blade requires an oscillating drive signal which matches the resonant frequency of the fan blade. An Inverter Drive Circuit is available which delivers a periodic output signal to the fan when a low DC voltage, up to 15VDC, is applied to its input.

The oscillating blade creates a high velocity flow stream emanating from the blade's leading edge. Air intake is above and below the swept out volume of the blade.

The piezo fan is small, flat, lightweight, reliable, and cost effective. It produces negligible heat (making it ideal for sealed enclosures), negligible EMI, consumes low power, and operates over a wide temperature range.

Inverter Drive Circuits convert a DC input voltage to an AC output voltage. The Low Power Inverter Drive Circuit converts a DC voltage (from 0 to +15 VDC) to an AC output voltage (from 0 to ± 15 Vpeak) while drawing very little power.

The Higher Voltage Inverter Drive Circuit converts DC input voltage (from 0 to +44 VDC) to AC output voltage (from 0 to ± 44 Vpeak) for driving low frequency (50 Hz - 450 Hz) piezo devices such as custom fans, choppers, vibrators, and benders at resonance.
