  • Symmetric or asymmetric position of plenum box
  • Plenum box with lining
  • End plates, end angles, corner sections
  • Different looks due to choice of black, grey or white air control elements

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

Nominal sizes

  • LN: 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900, 2000 mm
  • Diffuser face also available in intermediate sizes

Construction

Diffuser face finish

  • Anodised, E6-C-0, natural colour
  • P1: Powder-coated RAL 9010, pure white, gloss level 50%
  • P1: Powder-coated RAL 9006, white aluminium, gloss level 30%
  • P1: Powder-coated in any other RAL CLASSIC colour, gloss level 70%

Attachments

  • D: Damper blade for volume flow rate balancing
  • LS: Lip seal
  • L: Internal insulation
  • EP: Two end plates
  • EA: Two end angles


Single diffusers are factory fitted with end plates or end angles.

Accessories

  • EP: Two end plates
  • EA: Two end angles


For a continuous linear arrangement the end plates or end angles have to be ordered separately and fitted by others.

Construction features

  • Spigot suitable for circular ducts to EN 1506 or EN 13180
  • 4 suspension points for on-site installation (by others)
  • The manually adjustable air control elements have grooves that make it easier to adjust the elements and lock them in the required position
  • Spigot with groove for lip seal (if accessory with lip seal has been ordered)
  • Diffuser face sizes from 600 to 2000 mm, in increments of 1 mm
  • Plenum boxes are only available in nominal lengths

Materials and surfaces

  • Diffuser face made from extruded aluminium sections
  • Air control elements made of ABS plastic, UL 94, V-0, flame retardant
  • Plenum box made of galvanised sheet steel
  • End plates and end angles made of aluminium
  • Lip seal made of rubber
  • Lining is mineral wool with vinyl closed cell foam
  • Diffuser face with anodised finish, E6-C-0, natural colour
  • P1: Powder-coated, RAL CLASSIC colour
  • Air control elements similar to RAL 9005, black
  • G: Air control elements similar to RAL 9006, grey
  • W: Air control elements similar to RAL 9010, white


Mineral wool

  • Where the mineral wool comes into contact with air, it is faced with glass fibre fabric as a protection against abrasion due to airflow velocities up to 20 m/s
  • To EN 13501, fire rating class A1, non-combustible
  • RAL quality mark RAL-GZ 388
  • Biosoluble and hence hygienically safe according to the German TRGS 905 (Technical Rules for Hazardous Substances) and EU directive 97/69/EC
  • Inert to fungal and bacterial growth

Standards and guidelines

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

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.

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

Materials and surfaces

  • Diffuser face made from extruded aluminium sections
  • Air control elements made of ABS plastic, UL 94, V-0, flame retardant
  • Plenum box made of galvanised sheet steel
  • End plates and end angles made of aluminium
  • Lip seal made of rubber
  • Lining is mineral wool with vinyl closed cell foam
  • Diffuser face with anodised finish, E6-C-0, natural colour
  • P1: Powder-coated, RAL CLASSIC colour
  • Air control elements similar to RAL 9005, black

  • W: Air control elements similar to RAL 9010, white


Mineral wool

  • Where the mineral wool comes into contact with air, it is faced with glass fibre fabric as a protection against abrasion due to airflow velocities up to 20 m/s
  • To EN 13501, fire rating class A1, non-combustible
  • RAL quality mark RAL-GZ 388
  • Biosoluble and hence hygienically safe according to the German TRGS 905 (Technical Rules for Hazardous Substances) and EU directive 97/69/EC
  • Inert to fungal and bacterial growth

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.

  • Flyt luftreguleringselementet i nærheden af studsene på en sådan måde, at det er muligt at indsætte en skruetrækker


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.
