General information

Application

  • Type PURELINE35 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

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 PureLine35 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, PureLine35 diffusers may also be used for extract air.

Slot diffusers of Type PURELINE35 with individually, manually adjustable air control blades 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 duct connection
  • Diffusers with a shorter plenum box as well as non-active diffusers require a rear blanking plate; length of blanking plate = L1 – L3
  • For a continuous linear arrangement connect the diffusers with connecting pins and alignment plates
  • If necessary, carry out volume flow rate balancing with the damper blade

These are only schematic diagrams to illustrate installation details.
