NS = Connection size – Diffuser size
*     = size available only with airflow pattern S (1,2,3 or 4 directions)

Air is supplied both horisontally and vertically into the space through the front panel of the diffuser.

The supply air pattern can be directed radially in the direction(s) desired (1, 2, 3 and 4) by rotating the nozzles (model DKS/S). Horisontal swirl jet and vertical air patterns can also be achieved by adjusting the nozzles (model DKS/W).

Direction of the supply air jet has no effect on the pressure drop or the airflow rate.

The recommended maximum air temperature difference between supply and room air is 10 °C.
The maximum recommended temperature for plastic material is 60°C.

The diffuser is connected either directly to the duct by screwing or riveting, or alternatively to the Halton TRI or Halton TRH balancing plenum.

Direct the flow pattern in the desired directions by individually rotating each nozzle in order to meet the required specifications.

A minimum safety distance upstream of the diffuser of 3xD is recommended.

Installation with plenum Halton TRI

The collar of Halton TRI plenum can be installed either internally in the plenum or externally on the bottom of the plenum. The height of the unit is presented in the table below for the external installation. When the collar is installed internally, the total height H1 is reduced by 60 mm.

The technical performance for the combination of supply air diffuser and Halton TRI plenum is presented separately for the two different installations.

It is not possible to adjust the airflow rate in Halton DKS itself.

In order to enable the adjustment and measurement of airflow rate it is recommended to connect the diffuser to TRI balancing plenum. The supply flow rate is determined by using the MSM measurement and adjustment module.
Open the front panel and pass the tubes and control spindle through the plastic nozzle. Replace the front panel.

Measure the differential pressure using a manometer. The flow rate is calculated using the formula below.

Adjust the airflow rate by rotating the control spindle until the desired setting is achieved. Lock the damper position with a screw.

Replace the tubes and spindle in the plenum and replace the diffuser front panel.

The k factor for installations with different safety distances
(D= duct diameter)

Detach the front panel of the diffuser by gently pulling it down and let it balance on the hinges. Each nozzle can be easily removed by pressing the stoppers and then pushing the nozzle through the front panel.

Wipe the nozzles and the front panel with a damp cloth. The nozzles are replaced into the front plate by pushing. Reattach the front panel.

Option with balancing plenum

Remove the measurement and adjustment module by gently pulling the shaft; (not the control spindle or measurement tubes!).

Wipe the parts with a damp cloth, instead of immersing in water.

Reassemble the measurement and adjustment module by pushing the shaft until the unit meets the stopper.
Push the front panel back into place so that the springs lock.

The diffuser must be made of epoxy-painted steel with a white (RAL 9003) standard colour. Air is supplied through plastic nozzles, which must have a two-slot design in order to ensure efficient mixing of supply air. Nozzles must also be individually adjustable in order to provide high flexibility for the adjustment of the throw pattern.

Option 1: No balancing plenum

The diffuser has a galvanised steel casing with a spigot with integral gasket for connection to circular duct.
The diffuser has a detachable perforated front panel that provides access to the duct.

Option 2: With balancing plenum

The diffuser is connected to a balancing plenum equipped with a measurement and adjustment module.
The diffuser has a detachable front panel that provides access to the measurement and adjustment module in the plenum.

The balancing plenum has a spigot with integral gasket for air-tight duct connection.
The balancing plenum has sound attenuation material made of polyester fiber with a washable surface or mineral wool.
