Architectural diffusers
The only part of the systemanyone sees.
In most buildings the diffuser is the one visible piece of the HVAC system. EffectiV designs diffusers that architects and interior designers choose for their form, finish and colour, and that engineers specify for their performance.
01
Designed to be seen
Round, square and linear faces with clean lines, conceived as part of the ceiling rather than as a mechanical accessory.
02
Finished to belong
Steel and aluminium, powder-coated in any RAL colour, with coloured concave elements on NEX: the diffuser matches the ceiling, the wall or the exposed duct, or stands out from them.
03
Engineered to perform
High induction that mixes the air before it reaches the occupants: more comfort, less energy, no compromise on the design.
Projects
In real spaces.
A few projects made with our diffusers, for inspiration. You will find more photographs on each product page.

Forms
A form for every ceiling.
From a single circle to a continuous line, every family keeps the same standard: a clean face and high-induction mixing.
Finishes
Dressed to impress.
Every diffuser can be powder-coated in any RAL colour: white to disappear into the ceiling, black to show on an exposed duct, or the colour of the space. NEX diffusers go further, with coloured concave elements set into the face.
Performance
Architectural does not mean compromise.
Some people think of architectural diffusers as purely aesthetic products. Ours measurably improve thermal comfort and energy efficiency.
Thermal comfort
High induction mixes supply air with room air before it reaches anyone: no drafts, no stratification.

Better mixing lowers the load on the equipment upstream, in heating and in cooling.
Learn moreIndoor air quality
More effective air distribution delivers fresh air throughout the occupied zone, per ASHRAE 62.1.
