Function

Air is supplied into the space through the side slots and mixed with the room air outside the diffuser.
Recommended maximum air temperature difference between supply and room air is 10 °C.

The throw pattern can be deflected in different (1, 2 and 3) directions with the deflection parts (included in delivery).
Deflection part not needed for 4 direction supply or exhaust airflow .

Installation

The diffuser is connected either to the duct by screwing or by riveting or alternatively to the Halton TRH or TRI balancing plenum. The duct connection spigot is equipped with a seal gasket. The diffuser can be installed:

  • Flush with the ceiling
  • Flush with out the ceiling

The desired flow pattern is selected during installation with the deflector parts, according to the Installation and maintanence guide.
In an exhaust application deflector part is not used.

The recommended minimum safety distance upstream of the diffuser is 3xD with straight duct. When using balancing plenum no safety distance is required between the diffuser and the plenum.

NOTE: Step-by-step instructions on how to install the diffuser can be found in the Halton Jaz Cloud Ceiling Installation and maintenance guide. To download the guide go to the "Downloads" section.

Adjustment

The diffuser itself has no means for airflow adjustment.

In order to enable airflow adjustment and measurement of supply airflow rate it is recommended to connect the diffuser to the Halton TRI or TRH balancing plenum. The supply flow rate is determined by using the measurement and adjustment module MSM. In case of exhaust air, use of adjustment module MEM is recommended. It is not possible to measure exhaust airflow rate with adjustment module MEM.

Open the front plate and pass the tubes and control spindle through the side slot of the diffuser. Replace the front panel.

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

∆pm      Measured pressure [Pa]
k           The k factor given as a function of mounting and diameter
qv         Airflow rate [l/s]

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

Set the tubes and spindle back into the plenum and push back the diffuser front panel.

Servicing

Open the front panel of the diffuser and clean the parts by wiping them with a damp cloth.
Push the front panel back into place so that the springs lock.
 

Option with balancing plenum

Open the front panel of the diffuser.

Remove the measurement and adjustment module by gently pulling the shaft.
Note: Not the control spindle or measurement tubes!

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

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

Specification

The diffuser is made of painted steel with a white (RAL 9003) standard colour or stainless steel (EN1.4404/AISI 316L). Air is introduced into the space through the side slot, ensuring a high mixing rate. The flow pattern of the diffuser is as standard for 4 directions. It is adjustable in 1, 2, or 3 -way directions by shaping the deflector.
 

Alternative 1: Without balancing plenum

The diffuser has a spigot with integral gasket for connection to circular duct.
The diffuser has a detachable solid or perforated front panel to provide access to the duct.
 

Alternative 2: With balancing plenum

The diffuser is connected to a balancing plenum equipped with a measurement and adjustment module.
The diffuser has a detachable solid or perforated front panel to provide access to the measurement and adjustment module in the plenum.

The balancing plenum has a spigot with integral gasket for airtight duct connection.
The balancing plenum comprises sound attenuation material made of polyester fibre with a washable surface or mineral wool.
