  • Application
  • Description

Application

  • Type VSD50-1-LT slot diffusers are used as supply air or extract air devices or as supply and extract air combinations in comfort zones
  • Angled one-way air discharge for turbulent flow (mixed flow ventilation)
  • High induction results in a rapid reduction of the temperature difference and airflow velocity (supply air variant)
  • For variable and constant volume flows
  • For supply air to room air temperature differences from –10 to +10 K
  • For room heights up to 4 m (lower edge of suspended ceiling)
  • For the space saving installation into lightweight partition walls with a 50 mm wide metal support structure and a wall thickness of 100 mm

Special characteristics

  • Individually adjustable air control elements to meet individual local requirements
  • High induction results in a rapid reduction of the temperature difference and airflow velocity
  • Diffuser face has been optimised for maximum volume flow rate at low sound power levels
  • Internal acoustic lining that reduces room-to-room cross talk through the ductwork
  • Diffuser face with spring clip fixing that allows for easy installation of the diffuser face after drywalling is complete

Nominal sizes

  • LN: 550, 1175 mm

Variants

  • VSD50 -1-LT: Slot diffuser for supply air or extract air
  • VSD50 -1-LT-AZ: Slot diffuser as a supply and extract air combination (only LN 1175 mm)
  • VSD50 -1-LT-.../WW: White air control elements
