Ak [m²] - The free surface
X [m] - The length of the air jet at a speed of 0.25 m/s
NR [dB (A)] - Noise level for 8dB room attenuation
∆Pt [Pa] - Pressure loss
Veff [m/s] - Air speed in the diffuser
Values are provided for a room height of 2.7m.
The length of the air jet is given for horizontal discharge.
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 steel sheet and is equipped with suspension lugs.
On request, the plenum can be insulated with 6 mm thick elastomeric rubber.
The perforated damper is mounted on the adapter spigot and has the role of uniformizing and balancing the air flow.
The diffuser is mounted in a false continuous ceiling or on the wall.
The fixing of the plenum diffuser is done by means of “U” type mounting systems (bracket), positioned inside the plenum and the screws.
