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.

Designed to be seen

Round, square and linear faces with clean lines, conceived as part of the ceiling rather than as a mechanical accessory.

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.

Engineered to perform

High induction that mixes the air before it reaches the occupants: more comfort, less energy, no compromise on the design.

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.

01 · 5 models

Round

Swirl, concave elements or plaque: a single circle on the ceiling, with high-induction mixing behind it.

02 · 4 models

Square

For T-bar and drywall ceilings: square faces that sit on the ceiling grid.

03 · 2 models

Rectangular

Rectangular faces for hallways and walls: an adjustable diffuser or a nozzle panel, in the same proportion as the space.

04 · 3 models

Linear

Slots, linear jets and perforated duct: a continuous line that follows the architecture.

05 · 3 models

Jet

Adjustable nozzles, on the wall or on the duct, that disappear into slats and walls in large spaces.

06 · 2 models

Returns

Matching architectural return grilles, with or without a filter, so the loop closes on the same line.

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.

Energy efficiency

Better mixing lowers the load on the equipment upstream, in heating and in cooling.

Indoor air quality

More effective air distribution delivers fresh air throughout the occupied zone, per ASHRAE 62.1.
