Pneumatic external vibrator is widely used in water conservancy and power worksite, high-rise construction, mining, underground buildings and roads, railways, bridges with beams, T-beams and precast plants and other large precast concrete vibration chamber work, thereby reducing the clotting time of concrete, improving the strength, but also can be installed on a variety of vibration devices as a vibrating source.

Pneumatic external vibrator is powered by compressed air while driven. It produces mechanical vibrations by outputting torque, driving mechanism for the planetary rotating movement.

1. It features small size, light weight and easy operation.
2. The frequency and the exciting force are adjustable.
3. It has no danger of explosive in the gas place, meanwhile no influence in harsh environments such as high temperature.
4. It has overload protection, without failure due to overload.
5. It has a high starting torque, can directly start in the condition of load.
6. It has strong water resistance, not afraid of moisture.
7. With a diesel engine, it can be operated in the construction areas without electricity.
8. No bearing can reduce routine maintenance and avoid bearing wear problems at high speed operating conditions.
