Manufacture Quality Exhaust Metal Valve Disc Valve
Foshan Jianpin Air Conditioning Tech Co., Ltd. is a leading manufacturer specializing in aluminum egg crate cores and access doors/panels. We offer a wide range of air grilles and diffusers designed for various ventilation needs. Our products are known for their durability, efficiency, and aesthetic appeal.
Our louvers are widely used in 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 long periods, as they help avoid drafts while maintaining optimal airflow. The Weather Proof Louver is a popular choice for offices and shops due to its geometric design that blends well with square tile ceilings. It provides a 50% free area, ensuring high performance for both supply and extract applications.
The Disc Valve is ideal for exhaust air applications under isothermal conditions. It can handle variable airflow rates with low pressure drops and noise levels. Constructed from steel with a mounting ring, it offers long-term strength and rigidity. The smooth airflow passages ensure quiet and efficient operation, and the adjustable center cone allows for fine-tuning of airflow based on specific conditions.
Performance data is based on isothermal conditions with a room height of 2.7 meters and the diffuser mounted flush in an unobstructed ceiling. Noise ratings are calculated using a room absorption level of 10 dB. The table below shows the performance details for different product codes and airflow settings:
