Air Blow-off Nozzles

Remove dust, water, or other residues after storage, processing, washing, or rinsing of components/products

Questions? Ask an Engineer

In many industrial processes, bulk material or accumulated water must be removed from the surface of a product. Air blow-off nozzles make this process easy, effective, and versatile as compressed air is sprayed through a nozzle producing a flat fan shaped stream of air. The momentum of the high velocity air removes dust, dirt, and heavier materials such as metal chips. Thin layers of liquid can also be removed as the air stream physically moves water droplets and clears them off of a surface, while a spray of dry air also consumes water through evaporation. Compressed air is especially good at clearing a liquid or residue off surfaces because it will not scratch or rub against the object being dried as other drying systems do. Additionally, irregular shapes and sized objects can be dried or air washed by the air nozzles without special tooling or fixtures.

Selecting an Air Blow-off Nozzle:

Important factors to consider:

  • Available air flow rates
  • Available air pressure drop (∆P) across the nozzle
    • ∆P = supply pressure at nozzle inlet - process pressure outside nozzle
  • Material or residue to be removed
  • Size & shape of target object or area
  • Our experienced engineers can help determine which nozzle will perform as required with your design details
