Smoke Control Damper

As an original manufacturer specializing in the R&D and manufacturing of ventilation, smoke control and exhaust equipment for 23 years, our smoke control damper is the core control component in building fire smoke exhaust systems. It is mainly installed at smoke exhaust ducts and the front pipelines of smoke outlets to control the on-off of smoke exhaust pipelines, and is an indispensable safety device in the fire smoke exhaust systems of commercial buildings, underground spaces and industrial plants. The smoke control damper remains normally closed in daily operation. When a fire breaks out and generates smoke, the valve body can be opened via fire linkage signal or manual control to quickly discharge toxic smoke from the fire scene, reduce smoke concentration and create a safe environment for personnel escape and fire rescue. When the flue gas temperature in the pipeline reaches 280℃, the built-in fuse automatically triggers closure to prevent high-temperature flue gas with embers from spreading and causing secondary fires. All our smoke control dampers are integrally stamped from thickened plates, with excellent blade sealing performance and fast actuation response, stably adapting to various complex working conditions of fire smoke exhaust systems.

Based on years of production experience in fire ventilation equipment, we have carried out targeted optimization on the transmission structure and sealing design of smoke control dampers. High-strength rotating shafts and high-temperature resistant sealing components are adopted to ensure structural stability of the valve body in high-temperature flue gas environments, effectively reduce smoke leakage after closure, and comprehensively improve product safety performance. Each smoke control damper undergoes multi-process inspection during production. From plate cutting, forming and welding to assembly and commissioning, every link is controlled by dedicated personnel to ensure that actuation sensitivity, fire resistance and sealing performance all meet fire product standards. Currently, our smoke control dampers have been widely applied in fire smoke exhaust projects of large commercial buildings, underground garages and industrial plants across China, and are also supplied in batches to overseas fire engineering contractors and equipment purchasers, gaining wide market recognition for reliable quality.

The product is mainly used in fire smoke exhaust systems of high-rise buildings, smoke exhaust pipelines of underground garages, smoke exhaust projects of commercial complexes, smoke exhaust and ventilation of industrial plants, tunnel ventilation and smoke exhaust systems, subway ventilation and smoke exhaust facilities, fire smoke exhaust of large public buildings and other scenarios. It is a core safety component in building fire smoke exhaust systems.

We are a national high-tech enterprise holding multiple patents related to ventilation, smoke control and exhaust equipment. All series of fire ventilation products are accompanied by test reports issued by national authoritative testing institutions, with all performance indicators fully complying with national fire product standards and industry specifications. Our production process strictly follows a standardized quality management system, with full traceability from raw material procurement to finished product delivery, ensuring stable and reliable quality for each batch. We also accept third-party arrival inspection entrusted by customers to fully safeguard their procurement rights and interests.

We have established a complete full-process quality control system, with a professional quality inspection team in charge of quality management throughout production. Raw materials are subject to specification and material verification before warehousing. Self-inspection and mutual inspection are implemented for each process during production. Finished products undergo 100% full inspection before delivery, with core indicators including actuation performance, sealing performance and dimensional accuracy tested one by one - unqualified products are never allowed to leave the factory. The strict quality control system guarantees product quality stability and enhances the market competitiveness of our products overseas.

We support multiple international trade terms including EXW, FOB and DDP, with flexible delivery options according to customer needs. Both conventional and customized orders adopt the payment term of 30% deposit and 70% balance payment, supporting settlement in multiple currencies such as US dollars and euros. For long-term cooperative customers with large-volume procurement, we offer exclusive price discounts and priority production scheduling. We also allow mixed orders of different models and specifications in the same batch, fully meeting the diversified procurement needs of overseas purchasers and agents.
