Silvent 1011 Air Nozzle

Silvent 1011 Air Nozzle

Nozzle Features

  • Stainless steel Laval nozzle.
  • A Laval hole in the centre creates a concentrated, supersonic jet of air.
  • Halves the noise level and reduces air consumption dramatically, while maintaining the force of “open pipe blowing”.
  • The nozzle and the surrounding fins prevent dead end static pressure from exceeding 210 kPa (30 psi).
  • Fully complies with EU Machine Directive noise limitations and OSHA safety regulations.
