General information

Application
  • Slot diffusers are used as supply air or extract air devices in comfort zones
  • Particularly unobtrusive diffusers due to their sleek design
  • Installation into suspended ceilings
  • For room heights up to 4 m (lower edge of suspended ceiling)
  • For suspended ceilings; suitable for restricted ceiling voids due to the low overall height of the plenum box
  • Suitable for continuous linear arrangement
  • Adjustable air control elements allow for horizontal, angled or vertical air discharge
  • Mixed flow system with one-way or alternating air discharge, can be adapted to the building structure
  • 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

Special characteristics
  • Uniform air pattern reduces contamination of the ceiling due to induced room air
  • Horizontal, angled or vertical air discharge by means of manually adjustable air control elements
  • Comfortable indoor climate due to high induction and rapid reduction of temperature differences and airflow velocities
  • Attractive appearance thanks to anodised extruded aluminium sections (E6-C-0, natural colour) or powder coating (RAL CLASSIC colour)
  • Diffuser face has been optimised for maximum volume flow rate at low sound power levels
  • Suitable for continuous linear arrangement

Nominal sizes
  • LN: 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900, 2000 mm

Slot diffusers direct the supply air from ventilation and air conditioning systems into the room, either horizontally, at an angle or vertically. The resulting airflow induces high levels of room air, thereby rapidly reducing the airflow velocity and the temperature difference between supply air and indoor air. The result is a mixed flow ventilation in comfort zones, with good overall room ventilation, creating only very little turbulence in the occupied zone. Type PURELINE18 slot diffusers are factory fitted with manually adjustable air control elements. The airflow direction can be adjusted to meet various local requirements. Air discharge is one-way or alternating. Heating operation with vertical flow is also possible, as is angled air discharge. The supply air to room air temperature difference may range from –10 to +10 K. A damper blade (optional) enables volume flow rate balancing for commissioning. To give rooms an aesthetic, uniform look, Type PURELINE18 diffusers may also be used for extract air.
