DD06 – displacement diffuser

DD06 – displacement diffuser

Defined rectangular profile

The DD06 is a displacement diffuser with a rectangular body, a broad flat perforated front and a distinctive recessed upper profile. Its clear vertical outline can be considered alongside other architectural elements during room planning. Allow the installation position to support an unobstructed air path while providing space for routine access.

How displacement supply works

In low-level displacement ventilation, air cooler than the room enters with limited momentum and spreads near the floor. Heat from people and equipment generates upward air movement that draws in the surrounding air and carries heat toward high-level return or extract points. The final distribution reflects the combined effect of airflow, supply temperature, room loads and layout.

Plan the complete installation

Select the DD06 using the required airflow and the location of occupied areas. Keep the perforated face clear of furniture and other obstructions, and provide access for inspection and cleaning. Check dimensions, connection details, available pressure and acoustic requirements as part of the terminal selection. GERHMAN can review the room plan and design conditions to help coordinate the proposed arrangement.
