The diffuser is made of several stamped cones, made of epoxy-painted steel with a white (RAL 9010) standard colour.

The diffuser is suitable for installation on exposed ductwork or flush to the ceiling.

The diffuser is connected to the ductwork using a Halton TRI balancing plenum, which utilises polyester fibre with a washable surface as sound attenuation material.

The diffuser is connected to the ductwork using a Halton PLC plenum, which utilises mineral wool as sound attenuation material.

The plenum comprises an airflow measurement and adjustment unit.

The conical central core is removable.

The air discharge pattern is radial around the full perimeter of the air diffuser.
The cones form divergent sections, which creates underpressure inducing room air into the unit.

Function ▲

Supply air is divided into several jets through the cones.
The divergent sections of the diffuser create negative pressure under the diffuser so room air is induced into the supply air terminal. Room air and supply air mix.

This internal induction reduces temperature and the air velocity into the space.
The process is the same outside the diffuser between the supply and mixed room air, with external induction further reducing velocity and the temperature difference between supply and room air.

The diffuser can also be used as an exhaust unit.

Installation ▲

The Halton CAR diffuser can be installed flush with a suspended ceiling or fully exposed in the space.
The diffuser is connected directly to the duct using a Halton PLC plenum or Halton TRI balancing plenum. When it is connected directly to ductwork, a safety distance of minimum 3D upstream of the diffuser should be maintained.
 

Installation with plenum Halton TRI or PLC

Halton TRI

Halton PLC

When the Halton TRI spigot is installed in the plenum, the H dimensions can be 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.

Adjustment ▲

The airflow rate can be adjusted and measured only when the diffuser is installed.

In order to enable airflow adjustment and measurement of airflow rate, it is recommended to connect the diffuser to a plenum equipped with the MSM module.
The supply flow rate is determined using measurement and adjustment module MSM.

Detach the conical central core and pass the tubes and control spindle through the diffuser.
Measure the differential pressure with 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 push the conical central core back into place.

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

Service ▲

Remove the conical central core by unscrewing it from the frame.
Clean the parts by wiping them with a damp cloth.
Put each screw back in place, and screw on until the conical central core fits in place.

Option: with balancing plenum TRI + MSM or PLC + MSM

Remove the measurement and adjustment module by pulling gently on the shaft (not the control spindle).
Wipe the parts with a damp cloth, instead of immersing in water.

Reassemble the measurement and adjustment module by pushing the shaft until the module meets the stopper.
Put each screw back in place, and screw on until the conical central core fits in place.
