Pneumatic tools are designed to shorten the working time as much as possible, without generating unnecessary costs for the workshop. Structurally, they are light, easy to use, safe and have smaller dimensions than mains or battery powered tools. The safety of pneumatic tools allows them to be used in services related to fuel or flammable and volatile substances. Pneumatic tools are divided into many product groups. Among others: impact wrenches, pneumatic ratchets, straight and angle grinders, pneumatic hammers, pneumatic screwdrivers, scissors and others. All these tools have one common design: the air motor with a pressure of about 6.3 BAR. NOTE: Engines require a proper air-oil mixture, which means the mixture should be dry, without water, and should contain oil to lubricate air tools.
