PURELINE50   

The clean solution for significantly less ceiling contamination


Perfectly integrated slot diffuser for large volume flow rates, which can be easily and inconspicuously installed in the suspended ceiling.

  • New areas of application – including as air curtains for food counters
  • High flexibility thanks to numerous standard variants
  • Extended range of applications, as now available with 1 to 4 slots
  • Very high comfort due to lower sound power levels and improved temperature and velocity reduction
  • Improved energy efficiency due to lower pressure losses

Application

Application

  • Type PURELINE50 slot diffusers are used as supply air or extract air devices in comfort zones

  • The many variants allow for flexible use as mixed ventilation systems and make them suitable for various applications

  • Unobtrusive integration into suspended ceilings

  • For room heights up to 4 m (lower edge of suspended ceiling)

  • Suitable for large volume flow rates. Thanks to the option of 1-4 slots, the scope of application is wide-ranging.

  • One-way or alternating air discharge can be adjusted on site to meet local requirements

  • 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 due to extruded aluminium sections with anodised finish 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, 750, 900, 1050, 1200, 1350, 1500, 1650, 1800, 1950 mm

  • Diffuser face can be ordered in mm increments, also in intermediate lengths



Variants

PL50-... :

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

  • -DS: Only diffuser face with extended border and screw fixing

  • -DF: Only diffuser face with extended border and spring clip

  • -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

  • Central position of plenum box

  • Spigot with groove for lip seal (only for accessories with lip seal)

  • Diffuser face available in mm increments between 600 and1950 mm

  • If the diffuser face is longer than the plenum box, the protruding areas of the diffuser face are covered at the reverse side.

  • Plenum boxes only available in nominal lengths

  • Extract air variant with air control elements

  • The optionally available neck extension in the standard dimensions 22, 47, 72, 97 and 121 mm can be used to compensate for structural conditions

  • Fixing material for the diffuser face is supplied separately with the variants -SF and -DS

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 air distribution in comfort zones, with good overall room ventilation, creating only very little turbulence in the occupied zone.

Type PURELINE50 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 horizontal. 

Heating operation with vertical flow is also possible, as is angled air discharge. 

The supply air to room air temperature difference can 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 PURELINE50 diffusers may also be used for extract air.

Specification text

Slot diffusers of Type PURELINE50 with individually, manually adjustable air control elements and 1, 2, 3 or 4 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 a choice of black, grey or white air control elements.
Variants with plenum boxes have 1 or 2 spigots which are arranged horizontally or vertically for symmetrical plenum boxes and horizontally for asymmetrical plenum boxes.
The plenum boxes are fitted with 4 suspension lugs.
The connection between the diffuser face and the plenum box can be fixed or 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)

  • Diffuser face has been optimised for maximum volume flow rate at low sound power levels

  • Suitable for continuous linear arrangement

Installation and commissioning

  • Preferably for rooms with a clear height up to 4.0 m
  • Flush ceiling installation
  • Horizontal or vertical duct connection
  • Diffuser faces with shorter plenum boxes and non-active diffusers have a slot cover on the rear
  • For a continuous linear arrangement, connect the diffuser faces with alignment plates
  • If necessary, carry out volume flow rate balancing with the damper blade
  • Suitable material for fixing the slot diffusers must be provided by others


    These are only schematic diagrams to illustrate installation details.


    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 -M): The damper blade can be adjusted even after the diffuser face has been installed.
