    Microblower (Air Pump)

    The greatest highlight of Murata microblower technology is the use of ceramics as the drive source. The structure is designed to function as an air pump using the ultrasonic vibration of ceramics, which can generate high discharge pressures of air from a compact, thin and silent air device.

    This page introduces the mechanism and operating principle of the air pump, and the characteristics of Murata's microblower (micro pump).

    Notes

    • A microblower is a device to suck / discharge air, and liquids cannot flushed directly. The body cannot be washed because it does not have a sealed structure, and has no waterproof function. Also, avoid using this product in environments with condensation.
    • Since the microblower sucks and discharges air, contaminants and dust in the air tend to accumulate inside the pump, and the contaminants and dust will influence the operation time. Use the microblower in a clean environment, or use a filter to remove at least submicron level of contaminants to prevent particles and dust from entering. (* The use of a filter does not guarantee suppression of the characteristics deterioration of the microblower.)
    • Particularly, the smoke from tobacco and mosquito-repellant incense, etc. have an influence on the life span of the product. Do not use the product in any smoky environment.
    • The microblower cannot be used for automobile applications (including accessories). Do not use this product for automobiles.
    • If the microblower is used for medical applications, murata requires a special contract to cover the use in the medical application to be agreed before start of mass production.Please contact us for details.
    • Do not handle the body of the microblower (including the nozzle, wiring, etc.) with bare hands.
    • Do not bend the terminals of the microblower.
