What advantages do pneumatic tools have over electrically powered equipment?
What will be an ideal response?
1. Flexibility. Air tools run cooler and have the advantage of variable speed and torque; damage from overload or stalling is eliminated. They can fit in tight spaces.2. Light weight. Air tools are lighter in weight and lend themselves to a higher rate of production with less fatigue.3. Safety. Air tools reduce the danger of fire in some environments where the sparking of electric power tools can be a problem. Air tools also do not use electricity, so the danger of electrocution is reduced.4. Low-cost operation and maintenance. Due to fewer parts, air tools require fewer repairs and less preventive maintenance. The original cost of air-powered tools is usually less than the equivalent electric type.
