The 20mm Humidifier Microporous Nebulizer Tablet is a 20mm diameter microporous ceramic disc operating at a resonant frequency of 1700±100KHz, rated for 5°C to 50°C ambient temperature. This microporous nebulizer tablet uses a fundamentally different atomization mechanism than solid piezo atomizer discs found in lower-frequency mist maker driver boards — instead of vibrating a solid surface to shear water at the surface, the microporous ceramic mesh has thousands of tiny pores through which liquid is forced by ultrasonic vibration, similar to the mesh technology used in medical nebulizers.
This 20mm piezoelectric humidifier component’s much higher 1700KHz (1.7MHz) resonant frequency compared to typical ~100kHz atomizer discs reflects this pore-extrusion mechanism — the mesh structure produces a finer, more uniform droplet size than surface-shearing discs, which is why mesh-type 20mm Humidifier Nebulizer Tablet components are common in compact personal humidifiers and portable nebulizer-style devices.
As a humidifier microporous nebulizer tablet, this part is typically sold as a replacement/spare for existing devices where the original mesh has worn out or clogged. Perfect for engineering students, get 20mm humidifier microporous nebulizer tablet from StemVolt. Its is ideal for humidification systems, mist generation devices, and environmental control projects requiring efficient ultrasonic atomization.
