A slot diffuser in a stretch ceiling is an air product: a narrow linear slot for supply or extract, built into membrane and profile — without a bulky grille in view.
At Alumineu: AEROOOM (harpoon), AERROLL (clip), and shadow-gap profiles with a ventilation role (e.g. X207 / INVISIA). Duct sizes and reducers only from product cards/CAT.
Word rule: never call lighting plain “diffusers”. Light diffuser ≠ slot air diffuser. With HVAC always say “ventilation / air”.
Agree runs, connections, and service early. Alumineu B2B from Poland.
### FAQ
Same as a light line? No. Here air; there light with a light diffuser.
AEROOOM vs AERROLL? Harpoon vs clip — by site system.
