Manufacture Quality Exhaust Metal Valve Disc Valve
Foshan Jianpin Air Conditioning Tech Co., Ltd.
Specializing in aluminum egg crate cores and access doors/panels, we offer a wide range of air grilles and diffusers designed for efficient ventilation solutions. Our products are ideal for commercial applications where air change rates up to 10 times per hour are required.
Our louvres are particularly suitable for environments where people work for long periods, as they help avoid drafts while maintaining optimal airflow. The weatherproof design is both functional and aesthetically pleasing, especially when installed in square tile ceilings. With a 50% free area, these units deliver high performance for both supply and extract applications.
The disc valve is specifically designed for exhaust air applications under isothermal conditions. It can handle variable airflow rates with moderate pressure drops and noise levels. Constructed from steel with a mounting ring, the valve ensures long-term strength and durability. The smooth airflow passages contribute to quiet and efficient operation, while the adjustable center cone allows for fine-tuning 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. Noise ratings are calculated with a room absorption level of 10db. Below is the selection data for different product models:
