Product Introduction
The Single Layer Adjustable Louver is a flexible airflow control terminal specifically designed for commercial building HVAC systems. Manufactured from high-strength aluminum profiles with blades adjustable from 0° to 180° for variable throw distance and diffusion angle. This versatile product can be used as both supply air outlet and return air grille, widely applied in office buildings, shopping malls, hotels, hospitals, and other commercial spaces.
Applicable Locations
With its flexible adjustability and diverse configuration options, the Single Layer Adjustable Louver is widely used in commercial building HVAC supply and return air systems. As a side-wall supply grille, it is typically installed on ducts or side walls. Typical applications include:
| Facility Type | Specific Application | Recommended Configuration |
|---|---|---|
| Office Buildings | Standard floor supply/return air systems | Aluminum + Herringbone damper |
| Hotels | Corridor supply, ballroom return air | Hinged structure + Filter screen |
| Shopping Malls | Public area air supply | 0-180° adjustable direction |
| Hospitals | Waiting areas, patient room supply/return | Stainless steel + Filter screen |
| Schools | Classrooms, library HVAC terminals | Aluminum, cost-effective |
Product Advantages
1. 0-180° Flexible Adjustment — Adapts to Different Airflow Needs
Blade angles are adjustable from 0° to 180° to achieve different throw distances and diffusion angles. Blades can be arranged horizontally (H-type) or vertically (V-type) to suit different installation orientations and airflow control requirements.
2. Dual Functionality — Supply and Return Air in One
Can be used as both supply air outlet and return air grille. As a supply grille, it can be paired with a herringbone damper (multi-blade opposed regulating valve) for precise airflow control. As a return grille, it can be manufactured with an openable structure and equipped with a filter screen for easy cleaning and maintenance.
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. Lightweight aluminum reduces ceiling load and simplifies installation and cleaning.
4. Multiple Structural Configurations — Adapts to Various Installation Scenarios
Fixed Type: Standard installation, cost-effective
Hinged Type: Openable design for easy cleaning and maintenance
Removable Core Type: Detachable core for flexible inspection and maintenance
5. Rich Accessory Options — Flexible Function Expansion
Herringbone Damper (Multi-blade Opposed Valve) : Precise air volume and velocity control
Nylon Filter Screen: For return air applications — captures dust and contaminants
Multiple Material Options: Aluminum, stainless steel, galvanized steel — adaptable to different environments
