  • Description

Application

  • Type DLK-Fb ceiling diffusers with integral fire barrier are used as supply air or extract air diffusers for comfort zones
  • For fire integrity in the event of a fire on the room side (DIN 4102-2, clause 7.2.1.)
  • Max. fire load in the false ceiling void: 7 kWh/m²
  • Release in the event of a fire is by fusible link
  • Horizontal four-way supply air discharge for 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 installation into mineral fibre false ceilings made by Odenwald
  • Important! Type DLK-Fb ceiling diffusers are not approved for self-supporting fire-resistant false ceilings; for such ceilings, Type KU-K30 fire dampers or Type FVZ-K30 fire protection valves must be used
