Displacement diffuser SD-H is a high-performance air distribution unit designed to efficiently extract pollutants from production areas, workspaces, and industrial zones. Thanks to its circular perforated construction and built-in adjustable damper, the SD-H ensures low-turbulence air distribution and stable indoor air quality, even with varying heat gains. Ideal for both floor and ceiling installations, this displacement diffuser offers flexible air discharge direction and minimal mixing with indoor air. Manufactured from galvanized sheet metal, it includes components such as a perforated cylinder, orifice rings, and a connection spigot. The damper can be controlled manually or with an electric servomotor, making the SD-H a reliable and adaptable solution for commercial and industrial ventilation systems.

• Displacement air outlets efficiently extract pollutants from production and work areas without significant mixing with indoor air.
• Placement of displacement outlets above the occupied zone or on the floor depends on pollutant type and internal heat load, achieving low pollutant and heat load factors.
• The circular displacement outlet with an adjustable damper is versatile for installation above or on the floor.
• Its adjustable air discharge direction ensures consistent indoor airflow despite varying heat gains.
• At about 3 meters height, it achieves a pollutant load factor of 55-57%, with a lower factor when on the floor (around 20%).
• Klimaoprema offers multiple systems for adjusting the outlet damper: three manual options, an electric servomotor, and a thermal control unit.
• The design of the circular displacement outlet includes components like a perforated cylinder, connection spigot, orifice rings, and an air deflection tube with a built-in adjustable damper.
• The outlet is made of galvanized sheet metal and generates a low-turbulence displacement flow.
