Application

Application

Type PureLine18 slot diffusers are used as supply air or extract air devices in comfort zones
Particularly unobtrusive diffuser due to its 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 the induction of 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
High-quality look 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

Functional description

Slot diffusers direct the air from 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 room 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 air pattern can be adjusted to meet different local requirements.

Air discharge is one-way or alternating horizontal.

Other patterns: heating mode with vertical air discharge; angled air discharge.

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

A damper blade (optional) simplifies volume flow rate balancing for commissioning.

To give rooms an aesthetic, uniform look, PureLine18 diffusers may also be used for extract air.

Nominal length	600 – 2000 mm, in increments of 100 mm
Number of slots	1 or 2
Minimum volume flow rate, with ∆t_z = –10 K	5 l/s or 17 m³/h
Maximum volume flow rate, with L_WA ≅ 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 programme.

Up to nominal length 1200 mm, sizing includes one spigot; from length 1300 mm, two spigots are required.

Slot diffusers of Type PL18, with individually manually adjustable air control elements and 1 or 2 slots.

Air discharge 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 a choice of 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, while 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 characteristics

Uniform air pattern reduces contamination of the ceiling due to the induction of 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
High-quality look 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

Installation examples, Installation details, Commissioning, Basic information and nomenclature

PL18-1/.../B00, installation in continuous ceilings

Anodised, E6-C-0, natural colour

PL plenum box, positioned on the left, in the centre, on the right

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

These are only schematic diagrams to illustrate installation details.

Volume flow rate balancing 00261789_0

Move the air control element near the spigots in such a way that it is possible to insert a screw driver

Volume flow rate balancing

When several diffusers are connected to just one volume flow controller, it may be necessary to balance the volume flow rates.

Slot diffusers with plenum box and damper blade (variant -D): The damper blade can be adjusted even after the diffuser face has been installed.
