2 As a rule, any flat fan or solid stream nozzle can be operated with air instead of liquid. However, you ll obtain the best results using the nozzle de signs we specially engineered for applications of compressed air or saturated steam. For further details, please refer to the next pages. In addition to air, various noz zle types are also suited for injecting saturated steam. Typical applications of Lechler air nozzles are, for instance, efficient blowing off and blow ing out, cooling, drying or cleaning. Multi-channel air nozzles. In comparison to single-hole air nozzles the advantages are as follows: Reduction of the noise level of up to 1 db Low service air pressure with the same blowing power Lower air consumption Better blowing effect over a longer reach Lower operating costs Air pressure [bar] Comparison of a conventional, single-hole nozzle with 3 the Lechler multi-channel round jet nozzle type.3 3 Flow rate [Nm3/h] 3 Noise level [db(a)] Flow rate [Nm3/h] Noise level [db(a)] In many industries and work shops compressed air has become an indispensable tool. Compressed air is needed for cleaning, blowing off, drying, conveying and for numerous other applications. Where uncontrolled com pressed air is applied, very often annoying, high-frequency hiss noises arise, which may cause serious harm to hearing. These»noises«are produced by turbulences generated at the air outlet. Their intensity depends on the shape of the nozzle orifice and on the air pressure. This means: the better and stronger the air jet is sup posed to be, the higher the health-injuring noise level and the higher the air consump tion and its cost. The11solution: Lechler multi-channel air nozzles, 1 featuring a significantly 9 reduced sound level, high blowing power and low air 8 consumption. The 7performance of multi channel air nozzles is based on partitioning the air inflow 3 1 air into single1 air jets. Air pressure [bar] channels, arranged to ensure optimum flow conditions, provide for a particularly uniform, straight and powerful overall air jet Air pressure [bar] 1 1 Lechler multi-channel round jet nozzle Conventional single-hole nozzle 1 3 Air pressure [bar] Note for calculation of measuring values: Blowing power: Blowing distance vertical mm on a scale, area x mm.
