— connection to the compressor supplying air using a hose. On the one hand, this option is not very convenient, because it requires the compressor itself; and the hose restricts freedom of movement and can create other inconveniences when working. On the other hand, pneumatic machines themselves are simpler, cheaper, lighter and more reliable than electric ones, they are less prone to heat and are better suited for long continuous work. In addition, such a tool is indispensable in some specific conditions — for example, at high humidity, when there is an increased risk of electric shock, or in an explosive environment, when sparking in mechanisms is unacceptable.
