Allgemeine Informationen

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



Nominal sizes

  • FLN: 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900, 2000 mm
  • Intermediate sizes of the diffuser face are also available (in increments of 1 mm)



Variants

PL18-... :

  • -*: 1 to 2 slots
  • -DF: only front rail with B00 profile and spring clip
  • -DS: only front rail with B00 profile and screw fixing


  • -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: Overflow rail which can be integrated into a slotted belt. The front rail has openings at the back through which air can flow. The fixing of the overflow rail must be done on site. The supplied connectors are used only for positioning and aligning the overflow rail
  • -BD: Blind rail that can be integrated into a slotted band. The diffuser face is closed on the reverse side so that there is no air flow through the blind rail. The blind rail must be fixed on site. The supplied connectors are used only for positioning and aligning the overflow rail


  • -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




  • Plenum box on the left (LE)




  • Plenum box on the right (RI)




Plenum box variant





  • Symmetrical plenum box with horizontal connection (HS)




  • Symmetrical plenum box with vertical connection (VS)




  • Asymmetrical plenum box with horizontal connection (HA)



Construction



Diffuser face finish





  • With anodised finish, E6-C-0, natural colour


  • P1: Powder-coated RAL 9010, pure white, GU50
  • P1: Powder-coated RAL 9006, white aluminium, GU30
  • P1: Powder-coated in any other RAL CLASSIC colour, GU70

Attachments

  • D: Damper blade for volume flow rate balancing




  • LS: Lip seal


  • L: inner lining


  • EP: 2 end plates




  • EA: 2 end angles


Single diffusers are factory fitted with end plates or end angles. Either end plates or end angles can be used for the front end for continuous linear arrangements.


Accessories
  • EP: 2 end plates


  • EA: 2 end angles


For slot diffusers as continuous linear arrangement, the end plates or end angles must be ordered separately and installed on site. 2 alignment plates for connecting the front rails to each other are supplied separately with each slot diffuser without a factory-fitted end piece.


Construction features



  • Spigot suitable for circular ducts to EN 1506 or EN 13180


  • 4 suspension lugs on plenum box for mounting by the customer


  • Manually adjustable air control elements with detent for defined adjustment of the air distribution


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


  • Diffuser face available in mm increments between 600 and1950 mm




  • Plenum boxes only available in nominal lengths




  • Extract air variant without air control elements (E)




  • If the diffuser face is longer than the plenum box, the rear side of the protruding diffuser face ends are covered.




  • Factory set for a particular air pattern, manually adjustable on site (by others)




  • Diffuser face fixing material for variants -SF and -DS supplied separately



Materials and surfaces

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.
