Pneumatic wrenches

Pneumatic (compressor)

— powered by compressed air coming from the compressor. Air tools are considered safer than power tools, and in some situations (for example, in places with an abundance of flammable vapors, such as car service stations), they are the only option that is acceptable from a safety point of view. It is also worth noting the relatively small size of such devices with a fairly high power. On the other hand, the need to use a compressor complicates the entire system and makes it more expensive, and the efficiency is low, which affects costs.
