Core Product Features
- Multi-Claw Structure: The blades are arranged in a “claw-like” pattern, typically with 4 or 6 claws. The angle of each claw can be independently adjusted to achieve different airflow combinations.
- Airflow Range: Airflow diffuses simultaneously in multiple directions, covering a wide area and quickly balancing the temperature of large spaces.
- Material and Manufacturing Process: Primarily made of aluminum alloy with a powder-coated surface, ensuring durability. The blade adjustment damping is moderate, preventing loosening.
Applicable Scenarios
Core Scenarios: Locations requiring large-area, uniform airflow (conference rooms, lecture halls, shops, restaurants, school classrooms).
Special Scenarios
Open-plan offices, multi-functional halls, and other densely populated, open spaces.
Core Value
- Full Coverage: The multi-claw blades achieve 360° airflow without dead zones, avoiding airflow dead spots and resulting in more even temperature distribution.
- Flexible Adjustment: The airflow direction can be adjusted according to personnel distribution, achieving “on-demand airflow” and improving energy efficiency.
- Adjustable: Easy to install: Modular design allows for direct embedding into the ceiling, making it compatible with various central air conditioning systems.
