The timeless, stream lined and light design of HALO forms a horizontal throw-pattern. The device suits a wire range of air flow rates making it an ideal option for a variety of projects.

The diffuser forms a truly stylish entity while attached into a ceiling and leaves the space finished up to the smallest details. With its unique attachment mechanism, no attachment structures, adjustment mechanism or ducts are visible from behind the front plate.

For high-class air distribution

Due to its functional construction HALO forms a wide-spread, horizontal throw-pattern quietly and does not cause feeling of draught. The throw-pattern can be directed into 1,2,3, or 4 directions.

While using HALO and FLO plenum box together, the advantages of FLO’s highly accurate and sturdy adjustment mechanism can be attained.

Two options for installation

HALO suits coffered ceilings with a 600×600 attachment plate. A smaller collar joint attachment plate can be used when the diffuser is placed on an even ceiling.

HALO diffusers also suit exhaust air. In this case we recommend using FLO plenum box.

Qualities:

• distinctively light and streamlined design
• horizontal throw-pattern
• directable throw-pattern
• two options for attachment plate

Throw pattern

Throw length

4 directions

Throw length data values are measured with isothermal supply air.

Airflow is directed at 4 directions, installed against the ceiling without a plenum box.

Factors

No. of directions                    Throw length L_0,2                  Sound level dB(A)

The data applies to both HALO models.

We recommend using FLO plenum box for supply air.
