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 designs we specially engineered for applications of compressed air or saturated steam. In addition to air, various nozzle types are also suited for injecting saturated steam. Typical applications of Lechler air nozzles, for instance, are efficient blowing off and blowing out, cooling, drying, or cleaning.
The problem: Noisy air nozzles
Where uncontrolled compressed air is applied, very often loud, high-frequency hissing noises arise, which at worst could cause harm to hearing and at best are very annoying to deal with. These "noises" are produced by turbulence 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 supposed to be, the higher the health-injuring noise level and the higher the air consumption and its cost.
The solution: Lechler’s WHISPERBLAST® multi-channel air nozzles
The WHISPERBLAST air nozzle features a significantly reduced sound level, high blowing power, and low air consumption. The performance of multi-channel air nozzles is based on partitioning the air inflow into single air jets. Sixteen air channels, arranged to ensure optimum flow conditions, provide for a particularly uniform, straight, and powerful overall air jet.
In comparison to single-hole air nozzles the WHISPERBLAST advantages are as follows:
