The range of applications has not reached its limit. In all these applications two aspects should be taken into consideration: Generating compressed air requires money and the high-frequency noise, this occurs mainly at high pressures and by using single orifice nozzles and can damage hearing. Therefore it is necessary to use compressed air as economically as possible and to use modern technics of low noise. Measuring device for noise level dB(A) 1000 mm Blowing power, air consumption and noise level are the three decisive criterions for the selection of air nozzles. In order to reach comparable values Lechler uses measuring methods, which are typical in the industry. pressluftd_pr_e_lec08172_ok 24.02.11 13:09 Seite 3 Modern Nozzle Technics for More Efficiency and Less Noise. The advantages for practical use are convincing: Higher capacity by better blowing power from larger distances and by an evenly directed air stream. Thereby the efficiency will be considerably increased. This new technology of using compressed air offers new areas for application. ▲ More comfortable working conditions by reducing the noise level by up to 12 dB. This corresponds to a reduction by a half of the noise for the human ear. ▲ By the development of new multiple spray nozzles with specially formed nozzle orifices, the noise causing turbulences at the air exit have been considerably reduced; at the same time an improvement of the efficiency was reached by the nozzle construction. Thus it is possible to reduce the air pressure – and also the air consumption – but maintain a constant blowing power. ▲ Lower energy costs by lower working-air pressure at the same blowing power. Thereby the air consumption will be considerably reduced. This positive effect was reached mainly by dividing the air stream into smaller air streams. Hereby the incoming compressed air is led evenly into air channels, which are favourably arranged with regard to streaming. The result is a particularly even and powerful total air stream. 110 Noise level [dB(A)] 100 90 80 70 60 0 1 2 3 4 5 6 Air pressure [bar]
