Description

General Information

Application

  • Circular VAV terminal units for use in ventilation and air conditioning systems
  • For controlling, restricting, or shutting off supply and extract air flows
  • Closed-loop volume flow control using an external power supply
  • For variable or constant volume flow systems
  • Shut-off by means of switching (by others)
  • Can also be used for duct or room pressure control with suitable control components

Special features

  • Integral effective pressure sensor with 3 mm measuring holes (resistant to dust and pollution)
  • Factory set-up or programming and aerodynamic function testing
  • Parameters can also later be set on the control component; additional adjustment device may be necessary
