305 Components and spare parts from page 474 to 482 alid until December 31, 2019 Pneumatic tools / machinery When using pneumatic tools, there are various different parameters to consider to achieve the best possible result. Our operating instructions contain technical information, e.g. details on working pressure, hose diameter, etc. These details must be observed at all costs, since they have a considerable impact on the pneumatic tool’s performance. Working pressure • Reducing the recommended working pressure by 1 bar results in a performance reduction of up to 25%. • Too narrow or too long a hose reduces the air flow rate and with it the performance of the product. • A higher than specified working pressure accelerates wear and tear of the tool. Compressor • A pneumatic tool is powered by compressed air. A compressor is needed to generate the compressed air. The compressor has to be chosen in such way that it can continuously generate the required amount of compressed air. • With our pneumatic tools we specify in the operating instructions how much air is needed to achieve the required output. Depending on the model, our impact wrenches require between 70 and 270 litres of compressed air per minute at a working pressure of approx. 6.3 bar. • Often the specifications on the compressor are stated “without pressure”. This means that when “150 litres per minute” can be found as a specification on a compressor, this is the amount of compressed air produced by the compressor without pressure. • If the required working pressure increases, the amount of air produced decreases drastically. For the production and storage of 150 litres of compressed air per minute at a working pressure of 6.3 bar, a large workshop compressor is required. An “ordinary household compressor” with a pressure air tank of 25 litres produces an average of 200 litres of compressed air per minute. In doing so, the motor (usually approx. 1.5 kW / 2 PS) works against pressure of 6.3 bar in the pressure air tank. This means that often only an effective potential of one tenth, i.e. approx. 15 litres per minute is left over. • Therefore it is advisable to align the specifications of the compressor and the tool which is to be used. Air hose • The hose diameter and length are both decisive factors for the full performance of the compressed air devices. The internal hose diameter should not exceed 10 mm in order to ensure the required air flow rate. The shorter the hose from the compressor to the device is, the lower the friction loss and the full pressure produced by the compressor is available to the device. Maintenance and care • The long service life of the pneumatic tool is critically dependent on maintenance. • Note the specifications in the operating instructions regarding storage and maintenance. • Use the HAZET Service package for easy maintenance of your devices.
