SLOT DIFFUSER FOR WALL INSTALLATION

Wall diffusers with adjustable air control blades and optional splitter for cross-talk sound attenuation for different wall thicknesses


  • Optionally with the front rails of PURELINE18, PURELINE35 or PURELINE50
  • Available in nominal lengths 450 - 1200 mm
  • Wide range of applications due to variants with 1 - 4 air slots
  • Simple and tool-free assembly of the front rail, e.g. after completion of all preparatory work
  • Installation in lightweight partition walls with 50, 75 or 100 mm stud frame width and 75, 100, 125 or 150 mm wall thickness
  • Optionally for supply air, extract air or as supply air/extract air combination


Optional equipment


  • Spigot for improved cross-talk sound attenuation
  • Various looks thanks to powder-coated slotted profiles and manually adjustable air control blades, optionally in black, white or grey
  • Damper blade in the spigot for flow rate balancing, adjustable via cable pulls when the front is mounted
  • Fixing bracket for wall mounting

General information

Application


  • Wall diffusers as supply air or extract air diffuser or as supply air/extract air combination in ventilation systems for comfort areas
  • Wide range of applications due to the choice of different front rails:
    • PURELINE18, PURELINE 50 with 1 - 2 air slots
    • PURELINE35 with 1 - 4 air slots
  • Air flow with ceiling effect or directly into the room as turbulent mixed ventilation
  • Depending on the setting of the air control blades, the minimum installation height is defined
  • High induction causes a rapid reduction of the temperature difference and the air velocity
  • For constant and variable volume flows
  • For supply air temperature differences of -10 to +10 K
  • For room heights up to 4 m (lower edge of suspended ceiling)
  • Different neck lengths for common wall thicknesses: 75, 100, 125 or 150 mm
  • Space-saving installation preferably in lightweight partition walls
  • Optionally with fixing bracket for wall mounting

Special characteristics

  • Uniform jet dispersion to reduce dirt deposits that occur on the wall due to induced room air
  • The air flow is one-sided and is manually adjusted by air control blades
  • Large penetration depths or throw distances due to direct air flow into the room
  • Airflow with ceiling influence for positive effects on air velocities and comfort:
    • First, the air flows vertically along the wall and is redirected under the ceiling
  • Splitter as cross-talk silencer (optional):
    • To reduce sound transmission to neighbouring rooms via the air duct system
  • Tool-free fixing for easy and safe installation of the front rail
  • Installation of the front rail still possible after completion of all preparatory work
  • Comfortable indoor climate due to high induction and rapid reduction of temperature differences and airflow velocities
  • High-quality appearance due to surface-treated extruded aluminium profiles with anodised coating or powder coating according to RAL-CLASSIC colour scale
  • The front rail has been optimised for maximum volume flow rate at low sound power levels

Parts and characteristics


Attachments

Spigot

  • -D: with damper blade for flow rate balancing
  • -LS: with lip seal to reduce duct leakage

Splitter

  • -CT: with splitter to improve cross-talk sound attenuation to reduce sound transmission via the air duct system

End pieces

  • No entry: front rail equipped at the factory with end brackets for circumferential covering of the installation opening

Wall diffusers allow the supply air of room air conditioning systems to flow with ceiling influence or directly into the room. The flow takes place with a high induction of the room air. This quickly reduces the air velocity and the temperature difference between supply air and room air. The result is a mixed ventilation system for comfort areas with good room air circulation and low turbulence in the occupied zone.

The wall diffusers can be combined with PURELINE 18, PURELINE35 or PURELINE50 range front rails. These have factory-set air control blades 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 may range from –10 to +10 K.

A spigot can be optionally integrated in the plenum box to increase the passage attenuation and reduce the sound transmission into neighbouring rooms.

Damper blades (optional) in the spigot enable the volume flow rate to be balanced during commissioning. The damper blade is adjusted via cable pulls and can also be adjusted when the diffuser face is mounted.

For an architecturally uniform design, the wall diffusers are used as extract air diffusers or as supply air/extract air combinations.

Specification text

Wall diffusers as supply air or extract air diffusers or supply air/extract air combinations for ventilating rooms in ventilation and air conditioning systems. Consisting of a plenum box with spigot for connection to the on-site duct system and the front rail. The air into the room is provided by air control blades integrated in the front rails. These air control blades are manually adjustable and enable airflow with ceiling influence or direct airflow into the room. Optional splitter for improved cross-talk sound attenuation.
