ECHO is an architectural diffuser with a front plate with circular holes, used to introduce or evacuate air.
The diffuser is recommended for installations with constant or variable airflow and is intended for spaces with heights between 2.7 and 4 m.
The design of the product determines a high level of induction rate.
The front plate has external dimensions 595×595 mm and the circular connection Ø250 mm.
For a uniform appearance of the enclosures, the ECHO diffuser can also be used for air evacuation.
The product is delivered with the following elements: mounting bracket, fixing screw, screw cover cap and sealing gasket.

2 - Fixing screw
3- ECHO diffuser
4- Bracket (mounting crossbar)
5 - Plenum box (opțional)
D [mm] – Diffuser connection diameter
Ak [m²] - The free surface
X [m] - The length of the air jet at a speed of 0.2 m/s
NR [dB (A)] - Noise level without room attenuation
∆Pt [Pa] - Pressure loss
The diffuser can be supplied with a plenum connecting to the circular duct, with horizontal or vertical connection. The plenum is provided with suspension elements (lugs) and bead roll on the spigot, for easy fixing of the flexible duct.
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 has 4 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 balancing the air flow.
The diffuser can be mounted in 600 x 600 mm T-bar false ceiling, continuous ceiling or suspended.
The fixing of the plenum diffuser is done by using a central screw screwed into the mounting bracket, positioned inside of the plenum box.
