The amplitude and frequency of the vibrator can be controlled by adjusting the air pressure. The piston outside the casing contains grease, which vibrates with the piston and offers a long service life. The pneumatic vibrator is made of aluminum alloy, providing good oxidation resistance and corrosion resistance after long-term use. Compressed air is used as the power source, offering low air consumption, safety, and energy efficiency. Commonly used for emptying shakers, screens, silos, and dispersion of bulk materials.
