Round Swirl Air Diffuser
- Nominal Diameter: 250 to 800 mm
- Airflow Rate: 100 m³/h – 3400 m³/h
Product Overview
The Jet Nozzle Diffuser is a high-performance air distribution component designed for long-distance and high-velocity airflow in HVAC systems. Crafted from spun aluminum sheets, it ensures durability, corrosion resistance, and lightweight performance. The nozzle features a mobile section within a fixed frame, allowing airflow angles to be adjusted by up to ±30°, enabling targeted ventilation for large or high-ceiling spaces.
This diffuser is available in single-walled and double-walled variants, supporting both vertical and horizontal air throws. Its aerodynamic conical design increases airflow velocity, making it suitable for applications such as auditoriums, shopping malls, industrial facilities, and theaters. The surface is finished with electrostatic powder coating in RAL 9010 (Pure White) or RAL 9016 (Traffic White), with custom colors available upon request.
