Double-layer adjustable mutil-vane air diffuser

The Double-layer Adjustable Multi-Vane Air Diffuser from Foshan Chancheng Hualianda is constructed from aluminum alloy with a thickness of 0.8 mm, featuring two independent layers of adjustable vanes that can tilt up to 30 degrees for directional airflow control. Each vane is precision-formed with a 12 mm spacing between blades, allowing for uniform air distribution without turbulence. The diffuser is designed to fit standard rectangular duct openings ranging from 150 mm to 600 mm in width, with a standard depth of 100 mm to ensure compatibility with most HVAC systems.

The aluminum alloy material provides natural corrosion resistance, making it suitable for environments with moderate humidity or chemical exposure, such as laboratories or light industrial facilities. The double-layer configuration improves air mixing by separating primary and secondary airflow patterns, reducing stratification and enhancing thermal comfort. Typical industry variants include powder-coated white or brushed aluminum finishes, though the supplier does not specify available color options. Surface finish is smooth with no visible weld marks, indicating stamping and forming rather than fabrication from multiple parts.

This diffuser is commonly specified in commercial buildings, healthcare facilities, and office complexes where precise air control is needed without noise disruption. Buyers include HVAC contractors, facility managers, and system integrators sourcing for retrofit or new construction projects. Packaging is in bulk cartons of 20 units, each unit individually wrapped in foam. Trade terms offered include FOB Guangzhou and CIF ports, with minimum order quantities typically aligned with full container loads, though the supplier does not state a fixed MOQ.
