Product Introduction
The Double Deflection Adjustable Louver is a precision air supply terminal specifically designed for commercial building HVAC systems. Manufactured from high-strength aluminum profiles, it features two layers of perpendicular adjustable blades that allow independent control of both horizontal and vertical airflow direction, achieving variable throw distances and diffusion angles. This product is primarily used as a supply air grille in office buildings, shopping malls, hotels, hospitals, and other commercial spaces.
Applicable Locations
With its dual independent adjustment capabilities, the Double Deflection Adjustable Louver is widely used in commercial building HVAC supply air systems, typically installed in ducts or on side walls as side supply grilles. Typical applications include:
Product Advantages
1. Dual Independent Adjustment – Precision Airflow Control
Double deflection louvers feature two layers of perpendicular blades that independently adjust horizontal and vertical airflow direction. Vertical blades control diffusion angle and airflow direction, while horizontal blades allow supply air to attach to the ceiling or tilt downward (for warm air supply). Different blade angle combinations achieve different throw distances and diffusion angles.
2. Two Frame Styles – Adapt to Different Interior Designs
Frame widths are available in wide frame and narrow frame options. Wide frames are suitable for commercial spaces where grille presence is not a concern, while narrow frames offer a more refined appearance for high-end hotels and office buildings.
3. Aluminum Alloy – Aesthetic and Durable
Manufactured from high-strength aluminum profiles with powder coating or anodized finish — corrosion-resistant, rustproof, and resistant to deformation or discoloration over time. Galvanized steel and ABS options are also available from some suppliers.
4. Volume Control Damper – Precise Airflow Regulation
An aluminum volume control damper (herringbone damper/opposed multi-blade damper) can be installed behind the grille to regulate air volume and velocity within optimal ranges. This configuration is widely used in process air conditioning applications requiring high precision temperature control.
5. Customizable Sizes – Adaptable to Diverse Project Needs
Face size, shape, and blade spacing can all be customized. Outer blades can be parallel to the long side or short side — selectable according to client requirements.
