Foshan Jianpin Air Conditioning Tech Co., Ltd. is a professional manufacturer specializing in aluminum egg crate cores, access doors, and panels. We offer a wide range of air grilles and diffusers designed for various ventilation needs. Our products are ideal for commercial installations where an air change rate of up to 10 times per hour is required. They are particularly suitable for environments where people work for extended periods, as they help prevent drafts and ensure a comfortable indoor climate.
Our Weather Proof Louver is one of the most popular choices in offices, shops, and other public spaces. The geometric design not only looks elegant but also allows for a 50% free area, ensuring high performance in both supply and extract applications. It’s known for its durability, aesthetic appeal, and efficient airflow control.
The disc valve is specifically designed for exhaust air applications under isothermal conditions. It can handle variable airflow rates with moderate pressure drops and low noise levels. Constructed from steel with a mounting ring, it provides long-term strength and stability. The smooth airflow passages ensure quiet and efficient operation, while the adjustable center cone allows for precise airflow control based on specific requirements.
Performance data is based on isothermal conditions with a room height of 2.7 meters and the diffuser mounted flush in an unobstructed ceiling. The table below shows the performance at 20% and 100% open positions of the center cone, including airflow, noise criteria (NC), and pressure drop (Pa). These values are calculated with a room absorption level of 10 dB.
