Variable Air Volume Damper (VAV)

Variable Air Volume Damper (VAV), referred to as VAV damper, is the core terminal control device of variable air volume air conditioning systems. It automatically adjusts the valve opening to change the supply air volume by real-time monitoring of regional temperature, thereby maintaining the regional set temperature and realizing overall system energy saving at the same time. Variable Air Volume Damper (VAV) integrates air valve body, DDC controller, electric actuator and air volume measuring device. It can precisely control supply air volume through PID algorithm, supports network communication with building automation systems, realizes centralized monitoring and global optimization, and is a key component of intelligent building air conditioning systems.

Our Variable Air Volume Damper (VAV) adopts pressure-independent control design, with built-in integrated air volume measuring device, which can detect actual air volume in real time and feedback adjustment, unaffected by system pipeline pressure fluctuations, with high air volume control accuracy. The valve body is made of high-quality galvanized steel sheet. The electric actuator has fast response speed and stable operation. The built-in controller supports multiple communication protocols and can flexibly connect to various building automation systems. With 23 years of manufacturing experience in ventilation and air conditioning equipment, our VAV damper has precise control and stable operation. We can customize control logic and communication protocols according to customer needs, adapt to different variable air volume system solutions, and provide efficient and energy-saving terminal air volume control solutions for various intelligent buildings.

• Commercial buildings: Variable air volume air conditioning systems in high-end office buildings, office buildings, and business complexes
• Hotel buildings: Variable air volume control in guest rooms and public areas of large hotels and high-end hotels
• Public facilities: Intelligent ventilation and air conditioning systems in hospital office areas, research and teaching buildings, airports, etc.

We support full-parameter customization of Variable Air Volume Damper (VAV). Different actuator configurations, controller types and communication protocols can be selected according to customers' system requirements, and valve body size and air volume range can also be customized. For special project needs, we can provide different configuration versions with temperature sensors and control panels, and can also adapt to material requirements for special working conditions. The minimum order quantity is 1 piece, the development cycle of customized samples is about ten days, and system docking technical support can be provided to assist customers in completing system commissioning.

We adopt special protective packaging for the precision electronic components of VAV damper. The controller and actuator are separately treated with shockproof and moisture-proof protection, and the valve body adopts reinforced packaging to ensure both mechanical and electronic components are not damaged during transportation. All product packages are marked with clear models, parameters and precautions, which is convenient for on-site receiving and storage. We support multiple trade terms such as EXW, FOB, DDP. The production cycle of customized products is about ten days, and batch orders can negotiate production scheduling. We regularly synchronize progress with customers during the production process.

We provide full-process technical services for Variable Air Volume Damper (VAV). Pre-sales assistance is available for system selection and scheme design. In-sales technical docking guidance can be provided. After-sales service includes one-year free warranty and lifetime technical support. For variable air volume systems, we can provide on-site commissioning services to assist customers in completing system commissioning and air volume calibration. For product quality problems within the warranty period, customers can enjoy the three-guarantee service of repair, replacement and refund. After the warranty period, services such as system upgrade and component replacement can be provided. We regularly follow up on system operation and quickly respond to various technical problems.
