- Visible grille or frame
- Interrupts clean ceiling lines
- Technical appearance dominates

DRS 125 is designed to integrate technical performance into a calm, uninterrupted ceiling surface.
Conventional ceiling components become part of the interior whether they are meant to or not. Conceiling products are engineered to perform their technical role while leaving the ceiling visually calm and uninterrupted.


The diffuser geometry directs air along the ceiling surface using the Coanda effect. This supports more comfortable air distribution and reduces the sensation of a direct downward draught.
Conceiling DRS 125 is a frameless ventilation diffuser developed specifically for integration into stretch ceilings. Instead of appearing as a conventional ventilation grille, it becomes part of the ceiling surface, helping to preserve clean architectural lines and a calm, uninterrupted interior.
The diffuser features a standard 125 mm duct connection and is suitable for both supply and extract air systems. Its geometry directs airflow sideways along the ceiling using the Coanda effect, reducing the sensation of direct downward draughts and supporting more comfortable air distribution throughout the room.
DRS 125 is designed for projects where technical performance and interior aesthetics are equally important. The visible textured white cover complements common stretch ceiling finishes. Where a closer visual match is required, the cover can be adapted using compatible ceiling material or an appropriate paint finish.
The diffuser body is installed before the stretch ceiling membrane is tensioned. During the final installation stage, the membrane is secured using the dedicated pressing ring, after which the fixing points are concealed by the decorative cover. This creates a precise, frameless appearance without visible conventional grilles.
DRS 125 is particularly suitable for:
With a recommended airflow of up to 90 m³/h, DRS 125 combines discreet ceiling integration, controlled airflow distribution and practical installation in one purpose-designed product.
Use these values when coordinating the product with the system, ceiling build-up and installation drawings.
Review the product dimensions, installation sequence and connection requirements before the stretch ceiling is installed.
