Slender curved profile
The DD04 is a displacement diffuser with a slender vertical form and a curved perforated front. Its proportions create a defined architectural element within the room. When developing the layout, consider both the diffuser’s visible profile and the space needed around it for air distribution, nearby circulation and routine access.
Air supplied near the floor
A displacement system supplies air cooler than the room at low level and with limited momentum. This air spreads close to the floor before joining the rising currents created by occupants and other heat sources. Heat is carried toward high-level return or extract points. Diffuser placement, furniture and the distribution of room loads all influence this process.
Project-specific selection
Choose the DD04 with reference to the required airflow, supply-temperature range and occupied positions. Preserve a clear path in front of the perforated face and allow access for cleaning and inspection. Confirm the final dimensions, connection details, pressure requirement and acoustic performance as part of the project selection. GERHMAN can review the proposed layout and design conditions with the project team.
The DD04 has a slender curved-front form and a perforated face for low-level displacement ventilation. Its vertical proportions offer a distinctive way to integrate the diffuser into an architectural layout.
