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

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.
