HALO-X suspended ceiling diffuser

HALO-X is an ultra stylish supply air diffuser for coffered ceilings with a front plate where a 600×600 ceiling plate can be embedded. When a ceiling plate is selected to be used as the front plate, the diffuser will form a unified, finished entity with the rest of the ceiling. HALO-X functions silently and without draught and suits also exhaust air.

Air flow range

5-170 dm³/s, 18-612 m³/h

Duct sizes

Ø 125-315 mm


Galvanized steel

Color options

RAL 9016 white (matte), RAL 9005 black (matte)


HALO-X forms a horizontal spreading pattern that can be directed in to 1, 2, 3, or 4 directions. The device suits a wide range of air flow rates which makes it a good option for a variety of projects.

The diffuser forms a distinctively stylish entity while attached in to the ceiling. HALO-X leaves the appearance finished. With its unique attachment mechanism, no attachment structures are visible from behind the front plate.

Thanks to it’s innovative construct HALO-X can either be faded into the ceiling surface or brought out with a contrasting colored plate or an acoustics plate. This offers an interior designer or an architect a lot of possibilities to design the space up to its finest details.

For high-class air distribution

Due to the diffuser’s functional structure, a wide-spread throw pattern that does not cause feeling of draught can be achieved. The throw-pattern can be directed in to 1, 2, 3 , or 4 directions.

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

Multiple options for installation

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

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