VSD15

  • TROX slot diffusers type VSD15 are generally suitable for continuous assembly and can be inconspicuously installed parallel to linear light arrays.
  • The air discharge direction can be adapted as necessary to the desired room conditions.

Application

  1. – Type VSD15 slot diffusers are used as supply air or extract air devices in comfort zones
  2. – Air discharge is one-way or alternating horizontal, or alternating angled; turbulent flow (mixed flow ventilation)
  3. – High induction results in a rapid reduction of the temperature difference and airflow velocity (supply air variant)
  4. – For variable and constant volume flows
  5. – For supply air to room air temperature differences from –10 to +10 K
  6. – For room heights up to 4 m (lower edge of suspended ceiling)
  7. – For suspended ceilings; suitable for restricted ceiling voids due to the low overall height of the plenum box
  8. – Ideal for suspended panelled ceilings with standard 16 mm gaps
  9. – Suitable for continuous linear arrangement


Special characteristics

  • Individually adjustable air control elements to meet individual local requirements
  • High induction results in a rapid reduction of the temperature difference and airflow velocity
  • Ideal for suspended panelled ceilings with standard 16 mm gaps
  • Suitable for continuous linear arrangement

Nominal sizes

  • LN: 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500 mm
  • Diffuser face available in intermediate sizes from 300 to 2000 mm, in increments of 1 mm

Functional description

Slot diffusers direct the air from air conditioning systems into the room, either horizontally or at an angle. 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 VSD15 slot diffusers have adjustable air control elements. The air pattern can be adjusted to meet different local requirements. Air discharge is one-way or alternating horizontal. Heating mode with angled air discharge is also possible. 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, Type VSD15 diffusers may also be used for extract air.


Quick sizing tables provide a good overview of the volume flow rates and corresponding sound power levels and differential pressures.

The maximum volume flow rates apply to a sound power level of approx. 50 dB (A) with damper blade position 0°.

Exact values for all parameters can be determined with our Easy Product Finder design programme.

Slot diffusers with individually manually adjustable air control elements and an aesthetically shaped face section with one slot, for one-way horizontal, alternating horizontal or alternating angled air discharge. For supply air or extract air. For installation into suspended ceilings, particularly into panelled ceilings with standard 16 mm gaps.

Ready-to-install component which consists of the diffuser face with individually adjustable black or white air control elements, and of a plenum box with side entry spigot and suspension lugs.

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

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