Pneumatic atomizing nozzles

Pneumatic atomizing nozzles are available in various designs to comply with specific spray and flow requirements:

  • self-aspiration (siphon principle)
  • supply of liquid from a vessel located at a higher level (gravity principle)
  • supply of liquid under pressure (pressure principle)
  • mixing of fluids inside or outside the nozzle
  • full cone or flat fan spray pattern
  • Hollow cone nozzles

    Two types of hollow cone nozzles are available:

    Axial-hollow cone nozzles
    • Finest drop particles
    • Narrow free cross-sections
    • Maximum spray angle 90°

    Eccentric-flow hollow cone nozzles
    • Coarser droplets than axial-flow hollow cone nozzles
    • Large free cross-sections
    • Wide spray angles up to 130°
    • Self-cleaning, non-clogging

    Full-cone nozzles

    Axial-flow full cone nozzles
    Lechler full cone nozzles have an extraordinarily uniform liquid distribution over the whole circular impact area.

    Tangential flow full cone nozzles
    Nozzles are, for instance, particularly suited for closed-circuit spraying of liquids with a high quota of solid matter, or for fire fighting applications.

    Cluster Head Nozzles
    Lechler cluster head nozzles achieve a very large surface of the sprayed liquid by adding various finely atomizing single nozzles.

    Flat fan nozzles

    Lechler flat fan nozzles stand for uniform liquid distribution and jet pressures. Particularly
    powerful jets are generated with spray angles up to 60°.
    Nozzles with small flow rates are especially suited for humidifying and spraying in general.
    The flow geometry of the nozzle allows to produce accurate, compact jets, available with different liquid distribution patterns.

    Solid stream nozzles

    Thanks to optimum flow geometries, Lechler solid stream nozzles produce compact, transparent solid stream jets of defined lengths. The almost turbulence-free liquid inflow achieves excellent efficiency, even without jet stabilizer inserts.

    For all cleaning processes, cutting operations and applications requiring perfect, punctiform jet impacts, i.e. whenever the point is to generate concentrated jet power, the precision of Lechler solid stream nozzles enhances productivity and performance of your plant.

    Air nozzles

    Air nozzles
    are used for dispersing air or steam in a concentrated and straight fan. Generally, air nozzles have a flat fan or solid stream spray pattern. When using conventional air nozzles, air is blown through a single hole. Often a loud, ear-splitting and hissing noise is produced. To avoid this unpleasant noise, Lechler has designed special multichannel air nozzles. Sound level and air consumption of these nozzles are very low.

    Tank cleaning nozzles

    Tank cleaning nozzles
    can be used for both small and large tanks and are available as both rotating and static
    sprays. All tank cleaning nozzles are operating at low pressures.

    The rotating nozzles (rotational cleaners)
    are driven by the cleaning liquid by means of specially positioned nozzles or by turbine (partly driven by gearbox).

    Rotational cleaners
    achieve very good cleaning of the entire tank surface as rapid-repetition impact loosens
    the dirt and washes it off of the inside tank surfaces.

    Static spray balls
    do not rotate. They are used primarily for washing down relatively small tanks and vessels.


    Our comprehensive range of accessories significantly contributes to optimizing the adaptability of Lechler nozzles to special requirements and prerequisites.

    No matter whether you want to change nozzles easily, to provide sealing or just to have an alternative fixing facility, you’ll profit in every respect from Lechler’s technical know-how and practical experience with accessories. As a result, your work is made easier, your capacity is better utilized and you’ll be saving cost to an extent you wouldn’t have thought possible.
