General information

Application

  • Type CFS slot diffusers for wall installation can be used for supply air, for extract air or as a supply and extract air combination in comfort zones.
  • Wide area of application thanks to choice of PURELINE18, PURELINE35 or PURELINE50 diffuser faces of various widths with 1, 2 or 3 slots
  • One-way horizontal or vertical air discharge creates a turbulent mixed airflow
  • Air distribution with or without ceiling effect (depending on installation height)
  • High induction results in a rapid reduction of the temperature difference and airflow velocity
  • 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)
  • Installation in lightweight partition walls with a thickness of 100 mm and with a 50 mm wide metal frame


Special features

  • Uniform air pattern reduces contamination of the wall caused by the induction of room air
  • Horizontal or vertical air discharge by means of manually adjustable air control elements
  • Horizontal air discharge allows for longer throw distances
  • The vertical airflow moves along the wall, towards the ceiling and eventually across the entire ceiling area, having a positive effect on airflow velocities and comfort levels
  • Acoustic lining reduces noise transmission through ducting between adjacent rooms
  • Easy and safe installation of the diffuser face without any tools after drywalling is complete
  • Comfortable indoor climate due to high induction and rapid reduction of temperature differences and airflow velocities
  • Attractive appearance due to extruded aluminium sections with anodised finish or powder coating (RAL CLASSIC colour)
  • The diffuser face has been optimised for maximum volume flow rate at low sound power levels

Slot diffusers for wall installation discharge the air from air conditioning systems into the room, either horizontally or vertically along the wall and towards the ceiling. 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 CFS slot diffusers can be combined with PURELINE18, PURELINE35 or PURELINE50 diffuser faces and are fitted with factory set air control elements that can be manually adjusted on site. The airflow direction can be adjusted to meet various local requirements.

The supply air to room air temperature difference can range from –10 to +10 K.

To increase transmission loss and reduce room-to-room crosstalk the plenum box is fitted with acoustic lining.

A damper blade (optional) enables volume flow rate balancing for commissioning. The damper blade of CFS-18 can be adjusted with cords even with the diffuser face in place.

The damper blades of CFS-35 and CFS-50 can be adjusted by sticking a screwdriver or similar object through the diffuser face.

To give rooms an aesthetic, uniform look, Type CFS diffusers may be used for supply air, for extract air or as a supply and extract air combination.

Specification text

Slot diffusers for wall installation, diffuser face with up to three slots and individually manually adjustable air control elements for horizontal or vertical air discharge.

The slot diffusers for wall installation can be used for supply air, for extract air or as a supply and extract air combination.

Installation in lightweight partition walls with metal support structure.

Ready-to-install component which consists of the diffuser face with individually adjustable black, white or grey air control elements and of a plenum box with side entry spigot. The mineral wool lining reduces noise transmission.

The diffuser face can be mounted to the plenum box without any tools after drywalling is complete. As no tools are required, fixing is easy and quick after drywalling is complete.

Two adjustable suspension lugs on the plenum box allow for fixing the diffuser to the wall or suspending it from the ceiling (by others).

The spigots are suitable for circular ducts to EN 1506 or EN 13180.

Sound power level of the air-regenerated noise measured according to EN ISO 5135.

Diffuser face made from extruded aluminium sections.

End angles made of aluminium.

Plenum box made of galvanised sheet steel.

Air control elements made of ABS plastic, UL 94, V-0, flame retardant. Lip seal made of Evoprene.

Mineral wool

  • Mineral wool that comes into contact with air is faced with glass fibre fabric as a protection against erosion due to airflow velocities up to 20 m/s
  • To EN 13501, fire rating class A1, non-combustible
  • RAL quality mark RAL-GZ 388
  • Non-hazardous to health thanks to being highly biosoluble in accordance with the Ordinance on Hazardous Substances and Note Q of the European Directive (EC) No. 1272/2008
  • Inert to fungal and bacterial growth


Equivalence criteria

  • Uniform air pattern reduces contamination of the wall caused by the induction of room air
  • Horizontal or vertical air discharge by means of manually adjustable air control elements
  • Acoustic lining in the plenum box reduces room-to-room cross talk as well as fan noise transmission through the ductwork
  • Easy and quick installation of the slot profile without any tools after drywalling is complete
  • Comfortable indoor climate due to high induction and rapid reduction of temperature differences and airflow velocities
  • Extruded aluminium sections with anodised finish or powder coating (RAL CLASSIC colour)
  • The diffuser face has been optimised for maximum volume flow rate at low sound power levels
