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 features

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

-PB: Plenum box only (for combination with DS)

-PF: Combination of diffuser face and plenum box with fixed connection

-SF: Combination of diffuser face and plenum box with detachable screw fixing

-CD: Air transfer section that can be integrated into linear runs. On the reverse side of the diffuser face, there are openings for the air to flow through. The air transfer section has to be fastened by others. The connectors supplied are only used to position and align the air transfer sections.

-BD: Non-active section that can be integrated into linear runs. The diffuser face is connected on the reverse side so that air is prevented from flowing through the non-active section. The non-active section has to be fastened by others. The connectors supplied are only used to position and align the air transfer sections.

-CS: Corner section

Position of the plenum box on the diffuser face, if the plenum box is shorter than the diffuser face

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.

Nominal lengths	600 – 2000 mm, in increments of 100 mm
No. of slots	1 or 2
Minimum volume flow rate, with Δt_z = -10 K	5 l/s or 17 m³/h
Maximum volume flow rate, with LWA ≅ 50 dB(A)	84 l/s or 302 m³/h
Supply air to room air temperature difference	-10 to +10 K

Quick sizing tables provide a good overview of the volume flow rates and corresponding sound power levels and differential pressures.

Exact values for all parameters can be determined with our Easy Product Finder design program. Sizing up to nominal length 1500 mm includes one spigot; from length 1600 mm, two spigots are required.

Specification text

Slot diffusers of Type PURELINE18, with individually manually adjustable air control elements and 1 or 2 slots. Air distribution can be alternating horizontal, alternating angled, vertical, one-way horizontal to the left or one-way horizontal to the right. The slot diffusers are intended to be installed in suspended ceilings and are suitable for supply air and extract air. Ready-to-install component which consists of a diffuser face with black, grey or white air control elements. Variants with plenum box have 1 or 2 spigots. Symmetrically positioned plenum boxes may have side entry or top entry spigots. Asymmetrically positioned plenum boxes have only side entry spigots. The plenum boxes are fitted with 4 suspension lugs. The diffuser face fixing can be detachable or non-detachable. Spigots are suitable for circular ducts according to EN 1506 or EN 13180. The sound power level of air-regenerated noise is measured according to EN ISO 5135.

Special features

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 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

Suitable for continuous linear arrangement

Installation and commissioning

For room heights up to 4 m (lower edge of suspended ceiling)
Flush ceiling installation
Horizontal or vertical duct connection
If (L₃+ 5) < L₁, the plenum box can be positioned to the left, to the right or in the centre.
For a continuous linear arrangement connect the diffusers with alignment plates
If necessary, carry out volume flow rate balancing with the damper blade
Fixing material for fixing the slot diffusers is to be provided by others
