SCHAKO QA Displacement Air Diffuser

SCHAKO QA displacement air diffuser is designed for displacement ventilation in environments with high heat loads or polluted room air. It provides large area air distribution with low air outlet speeds. Fields of Application: QA displacement air diffuser is the ideal solution for offices, industrial workshops, laboratories and areas with high heat loads. It is particularly preferred in environments with polluted room air. Technical Specifications: - Volumetric flow range: 200 - 15000 m³/h - Air outlet speed: Low - Installation location: Floor area - Flow pattern: Large area distribution - Convection driven: Upward directed by heat sources - Low-induction flow - Pollutant displacement - Return air position: Above heat sources or at floor - Application type: Displacement ventilation Function: The supply air is blown into the room in the floor area over a large area via the displacement diffusers, at low air outlet speeds. The supply air spreads out across the floor and is directed upward by the convection currents of the heat sources. Due to the low-induction flow rate, the pollutant-containing air is displaced to the return air apertures, which should be mounted above the heat sources or, in the case of heavy pollutant particles, at the floor. Advantages: - Large area air distribution - Effective pollutant control with low-induction flow - Natural air movement with convection currents - Flexible return air positioning - Suitable for high capacity systems
