Bidirectional Airflow Adjustment
Air distribution needs flexibility. Our Aluminum Double-Layer Louver Grilles provide this flexibility. We use high-quality aluminum profiles. The surface is anodized or powder-coated. This gives a uniform, attractive finish with good corrosion resistance. The grille has two layers of adjustable blades. The outer blades adjust the horizontal air supply direction. The inner blades adjust the vertical air supply angle. This allows bidirectional airflow control. Yancheng Lima Air Conditioning Engineering Co., Ltd. has been making quality grilles since 1996.

Even Air Distribution with Low Noise
Comfortable spaces need even airflow. Our Aluminum Double-Layer Louver Grilles spread air evenly. The design gives a wide diffusion range. Airflow resistance is low. Noise levels are low. The blades operate smoothly and stay in position. The grille is easy to install and maintain. It looks good in any ceiling.

Common Uses in HVAC Systems
These grilles are found in many buildings. They work in offices, shopping malls, hotels, and hospitals. They are used as outlets for air handling units, fresh air units, and fan coils. Any space with a central air conditioning system can use them. Our factory uses advanced equipment for precise fabrication. We ensure each grille meets quality standards.
