Q:Which is good between pneumatic tools and power tools?

The use of pneumatic tools:1., the air is easy to obtain, and the work pressure is low, the used air can be discharged locally, without the need to recover the pipeline2. gas viscosity is small, flow resistance loss is small, easy to central gas supply and long-distance transportation3. pneumatic actuator, high movement speed4. the pneumatic system has a strong adaptability to the environment. It can work reliably in a wide temperature range, humid and dusty environment, with a slight leakage, no pollution to the environment, no fire and explosion hazards, and safe use5., simple structure, convenient maintenance and low cost6. long life of pneumatic components7. pneumatic actuators of the hydraulic output than small, fast, strong adaptability, can exercise in the flammable, explosive, heavy, damp, the impact of the harsh environment, no environmental pollution, long service life, simple structure, easy maintenance, low price.
