Silvent 780 LA Air Nozzle

Silvent 780 LA Air Nozzle

Nozzle Features

  • Stainless steel adjustable Laval nozzle that generates an enormous blowing force.
  • Compressed air is optimally used in this nozzle, which introduced a completely new blowing technology feature.
  • The effect is achieved by surrounding a core of air travelling at supersonic speed with a protective sheath of air moving parallel to the central air jet.
  • The design of the nozzle converts all of the energy stored in the compressed air into kinetic energy without permitting the air jet to expand laterally after it has passed through the nozzle.
  • The adjustable blowing angle allows a maximum of 30° adjustability around the centerline.
  • Fully compliant with OSHA safety regulations.
