Architecture meets engineering

Two professions.One diffuser.

In most buildings the diffuser is the only HVAC product that stays visible. The architect looks at the diffuser. The engineer looks at the air it moves. EffectiV designs diffusers that satisfy both, without compromise.

Two briefs

Each arrives with their own requirements.

01 · The architect

  • A form that belongs in the space
  • A finish and colour of their choice
  • Clean integration in the ceiling, wall or exposed duct
  • BIM objects for the model
  • One consistent line from room to room
NEX-C

Both, in the same product.

02 · The engineer

  • A throw that reaches the occupied zone
  • Mixing without drafts
  • A sound level (NC) under target
  • A known pressure drop
  • Reliable behaviour in heating and cooling

Two lenses

The same diffuser, seen by each.

Pick a product: on the left the finished project, on the right its airflow performance, from the manufacturer’s tested data. Change the neck size and velocity, and watch throw, sound and induction follow.
