The air spreads along the floor and is drawn into rising currents generated by people and equipment. High-level return or extract points complete the upward air path. The resulting distribution depends on the room layout, thermal loads and operating conditions.<\/p>\n<p style=\"font-weight: 400;\"><strong>Coordinate the installation<\/strong><\/p>\n<p style=\"font-weight: 400;\">Assess the DD03 using the project airflow, supply temperature and intended occupied positions. Keep its perforated face unobstructed and provide practical access for inspection and cleaning. Review the selected dimensions, connections, pressure and acoustic requirements together with the local air-velocity assessment. Share the architectural layout and system design conditions with GERHMAN to develop a coordinated terminal selection.<\/p>\n<p style=\"font-weight: 400;\">The DD03 presents a broad, curved perforated face for low-level displacement ventilation.
