Compact jet Radial Jet
The diffuser is connected either directly to the duct by screwing or riveting or alternatively to Halton TRI or Halton TRH balancing plenum.
The front vane panel can be reattached
Take care during installation to ensure that the cylinder can move freely and that the actuator has adequate installation space. There should be at least 50 mm clearance space above the top of the device when the cylinder is in the lowest position. The connection and fixing rivets or screws may not be located more than 50 mm below the upper edge of the diffuser.
A minimum safety distance upstream of the diffuser of 3xD is recommended.
1. Automatic adaptation of limited movement length to 0-10 VDC control signal
2. Direction of shaft movement based on 0-10 VDC control signal
3. Feedback signal
Ensure that the actuator has adequate installation space when installed in Halton TRI plenum. It is recommended to install the collar outwards.
The dimensions are with the outlet sleeve outside the plenum and diffuser without any actuator.

1. Control knob

The supply air jet is adjusted by changing the position of the cylinder.
When you turn the knob clockwise the throw pattern is changes from radial to compact.
It is not possible to adjust the airflow in Halton TSA itself.
In order to enable airflow adjustment and measurement of airflow rate it is recommended that you connect the diffuser TSA 250, 315 and 400 to the Halton TRI balancing plenum. The supply flow rate is determined by using the measurement and adjustment module MSM.
Pass the tubes and control spindle through the front vane 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. Replace the tubes and spindle in the plenum.
Remove the front vane panel and clean the diffuser by wiping it with a damp cloth, instead of immersing it in water.
Remove the measurement and adjustment module by pulling gently the shaft; (not the control spindle or measurement tubes!).
Wipe the parts with a damp cloth, instead of immersing them in water.
Remount the measurement and adjustment module by pushing the shaft until the module meets the stopper.
The diffuser consists of a frame with fixed internal profiled vane rings and a movable cylinder for throw pattern selection.
The front vane panel, the movable cylinder and the frame are made of powder painted steel, with a white (RAL 9003) as standard colour.
The airflow pattern is adjustable automatically using an electrical or wax-bulb actuator, (in applications where both heating and cooling are required.)
