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 are, for instance, efficient blowing off and blowing out, cooling, drying or cleaning.
