Washing installations

For this task it is essential that the nozzles are positioned in the right places. Lechler offers a wide range of different flat fan nozzles. These also include high-pressure nozzles and tongue nozzles. By choosing the right nozzle, the cleaning result and water consumption can be well adjusted to each other.

Düsen für die Hauptwäsche

Nozzles for the main wash

  • For this task high-impact flat fan nozzles or tongue-type nozzles are required.
  • The spray angle should be 30 to 45 degrees.
  • Due to their sharp jet, tongue-type nozzles are ideally suited for the low pressure.
  • High-pressure flat fan nozzles differ from low-pressure nozzles by virtue of their hardened nozzle mouthpiece, which gives these nozzles a longer service life.
