Duct Regulating Damper

As an original manufacturer deeply engaged in ventilation equipment manufacturing for 23 years, our independently produced duct regulating damper is a core supporting component for air volume balance adjustment in ventilation and air conditioning duct systems. It is mainly installed in main air supply/return ducts and branch pipelines, and precisely regulates pipeline air volume to ensure the operating efficiency and comfort of the entire ventilation system. It is a basic ventilation accessory widely used in HVAC engineering and industrial ventilation projects. The duct regulating damper drives multi-blade vanes in the valve body to rotate synchronously via the driving mechanism, realizing stepless air volume adjustment within 0-90°. It can flexibly adjust air supply volume according to ventilation demands of different zones, effectively solving problems of uneven pipeline air volume and insufficient local ventilation. Our duct regulating damper adopts a standardized valve body structure and precision transmission components, with good blade synchronization, uniform adjustment damping and accurate positioning without looseness, enabling stable long-term operation in various medium and low pressure ventilation pipeline systems.

Relying on more than 20 years of R&D and production experience in ventilation valve parts, we have carried out multiple optimizations and upgrades on the blade linkage structure and sealing performance of duct regulating dampers. An integrated linkage rod and wear-resistant shaft sleeve design are adopted to greatly reduce jamming and clearance problems after long-term use. Meanwhile, sealing strips are added to blade edges to effectively reduce air leakage in the fully closed state. All duct regulating dampers are cut and bent by CNC laser, with high dimensional accuracy and flat flange edges for convenient on-site installation and perfect matching with standard duct specifications. Each product undergoes opening/closing smoothness test and sealing sampling inspection before delivery to ensure stable and reliable performance. Currently, this product has been widely applied in ventilation and air conditioning systems of commercial buildings, industrial plants and purification workshops across China, and exported in batches to overseas markets including Europe, Southeast Asia and the Middle East, earning deep trust from HVAC distributors and engineering contractors.

The product is widely used in central air conditioning duct systems of high-rise buildings, ventilation pipelines of industrial plants, air volume balance adjustment of purification workshops, ventilation systems of commercial complexes, underground garage ventilation projects, hospital clean ventilation pipelines, data center room ventilation and other scenarios. It is an essential accessory for various ventilation and air conditioning systems to achieve precise air volume regulation.

We provide full-dimensional OEM/ODM customization services, and can customize duct regulating dampers of different sizes, materials and control modes according to customers' technical drawings, pipeline specifications and working conditions. Special performance versions such as explosion-proof and high-temperature resistant can also be customized for special working conditions. The minimum order quantity is as low as 1 piece, fully meeting customers' demands for trial orders, project supporting and batch stocking. The development cycle of conventional customized samples is about one week, enabling quick response to customers' sample testing and project selection needs. We also support mixed orders of different specifications and configurations in the same batch.

We provide customized packaging solutions according to customers' transportation scenarios. For long-distance sea and land export transportation, reinforced wooden frames and buffer protection packaging can be adopted to effectively avoid product deformation, paint scratch and other damage during transit. We support multiple international trade delivery terms including EXW, FOB and DDP for customers to choose flexibly according to their logistics arrangements. The production cycle of conventional standard products is about one week, and customized products take about ten days. During production, we regularly update customers on production progress and on-site photos to ensure on-time order delivery.

We offer a one-year quality warranty for all delivered products. In case of quality problems within the warranty period, customers are entitled to the three-guarantee service: repair, replacement and refund. Before sales, we establish an exclusive service file for each customer to assist with product selection and working condition adaptation. During sales, we provide full-process supporting services including transportation follow-up, installation technical guidance and commissioning assistance. After the warranty expires, we still provide lifelong maintenance service - only component costs are charged for faulty parts, and free technical support is provided. We conduct regular return visits to cooperative customers to promptly respond to and solve various problems in product use.
