DOTS is an architectural diffuser with individually adjustable nozzles, used for air supply.
Suitable for heating or cooling in spaces with long distances between the diffuser and the occupied area, concert halls, museums, etc.
DOTS can be mounted on a wall, ceiling or rectangular duct.
The diffuser is recommended in various ventilation applications for the introduction of air.
The constructive form and spherical design of the nozzles offer the possibility of an unlimited number of settings for the direction of the air jet.
The direction of the air jet can be easily adjusted manually to suit certain conditions and spaces.
Allows high airflow with low noise levels.

Ak [m²] - The free surface
X0,5 [m] - The length of the air jet at a speed of 0.5 m/s
X1,0 [m] - The length of the air jet at a speed of 1 m/s
Veff [m/s] - Air speed in the diffuser
NR [dB (A)] - Noise level without room attenuation
∆Pt [Pa] - Pressure loss
The diffuser can be supplied with a plenum connecting to a circular duct with horizontal connection.
The plenum is provided with suspension elements (lugs) and bead roll on the spigot, for easy fixing of the flexible duct.
The plenum is delivered insulated or uninsulated.
Optionally, a perforated damper can be mounted on the plenum connection to balance the air flow.
Adapter (plenum box)
The adapter is made of Z140 galvanized sheet metal and is equipped with suspension elements (lugs).
On request, the plenum can be insulated inside with 6 mm thick elastomeric rubber.
The perforated damper is mounted on the adapter spigot and has the role of balancing the air flow.
The diffuser can be mounted on the wall, ceiling or rectangular duct.
For ceiling mounting, the fixing of the plenum diffuser is done by means of “U” type fixing systems (brackets), positioned inside the plenum and the screws.
For mounting on a wall or rectangular duct, grille fixing screws can be used. Screw holes are only made on request.
