Variable Geometry Nozzle Laboratory Exhaust Fans

The Variable Geometry Nozzle (VGN) automatically adjusts to maintain the specified discharge velocity as airflow varies. This safely prevents re-entrainment in the make-up air unit. The VGN provides energy savings in reduced lab flow situations without introducing bypass air to maintain ANSI required outlet velocities.

OVERVIEW

Vektor-CS

The Vektor-CS safely maintains a constant discharge stack velocity at low volumes. This maintains ANSI guidelines for building design velocities regardless of laboratory exhaust airflow. The unit also reduces fan energy consumption on variable volume and demand-based ventilation systems. Drive components are out of the airstream. The motor is located at the roof deck level to the side of the common plenum. Vektor-CS is available in belt or direct drive and single to quadruple fan systems.

  • 1,500 to 32,000 cfm per fan
  • Up to 10 in. wg
  • Spark C or B resistant construction

Vektor-MS

The Vektor-MS is an inline fan with a bifurcated housing to keep drive components out of the contaminated airstream. Its variable geometry nozzle (VGN) technology recognizes changes in airflow and static pressure in an occupied space. This causes the fan’s operation to adjust throughout the day based on demand. Vektor-MS is available in belt or direct drive systems and up to four fans per system.

  • 2,000 to 32,000 cfm per fan
  • Up to 10 in. wg
  • Spark C or B resistant construction
