Smoke Control Damper (FSD)

Smoke Control Damper (FSD) is a precision control valve specially used in building smoke control systems. It is mainly installed in the air supply and smoke exhaust pipelines of smoke control areas such as smoke-proof stairwells, antechambers, and refuge walkways. By precisely adjusting the pipeline opening, it cooperates with positive pressure air supply or mechanical smoke exhaust systems to control the smoke concentration and pressure gradient in different areas, prevents smoke from invading evacuation safety areas, and builds a clear safety channel for personnel evacuation.

Our Smoke Control Damper (FSD) adopts a high-precision transmission mechanism, with precise valve opening adjustment, and can stably maintain the air volume and pressure difference requirements of the pipeline. The valve body is made of high-quality galvanized steel sheet, with high structural strength and good sealing performance. It can realize automatic action in conjunction with temperature-sensitive elements and fire control systems, and also supports on-site manual adjustment. With 23 years of manufacturing experience in the field of ventilation, smoke control and exhaust, our Smoke Control Damper (FSD) performs excellently in pressure difference stability, adjustment accuracy and operation reliability. It can adapt to various complex smoke control system solutions, and provide precise and reliable pipeline control solutions for building smoke prevention and control.

• Evacuation places: Positive pressure air supply and smoke control systems such as smoke-proof stairwells, fire antechambers, refuge floors, and refuge walkways
• Public buildings: Smoke control systems in densely populated buildings such as large shopping malls, hotels, hospitals, subway stations, and airport terminals
• Industrial scenarios: Smoke control pipelines in places such as large workshops, underground warehouses, and underground pipe galleries

We have a 13,000-square-meter self-built production base, equipped with a full set of automated production equipment such as laser cutting machines, CNC bending machines, and laser welding machines. We have more than 30 experienced production staff and a professional R&D team, with a monthly production capacity of 2,000 units for air valve products. Founded in 2003, the factory has been deeply engaged in the field of smoke control and exhaust for 23 years. It has full-chain service capabilities from product R&D, mass production to non-standard customization, and can efficiently respond to the procurement needs of various projects.

We support multiple trade terms and settlement methods. Conventional orders adopt the payment plan of 30% advance payment and 70% balance payment, and bulk procurement can enjoy corresponding discounts. We support settlement in multiple currencies such as US dollars, euros, and British pounds, and can negotiate business details according to customer needs. Repeat orders can enjoy priority production scheduling with shorter delivery cycles, ensuring customers' replenishment efficiency. Long-term cooperative customers can apply for more flexible payment term policies.

We have established a full-process service system covering pre-sales, in-sales and after-sales. In the pre-sales stage, professional personnel connect with customers to provide model selection and system adaptation suggestions. In the in-sales stage, we follow up the production progress and regularly feedback on-site conditions. After-sales service includes one-year warranty and lifetime technical support. For smoke control products, we can provide pressure difference commissioning guidance. For product quality problems within the warranty period, customers can enjoy the three-guarantee service of repair, replacement and refund. After the warranty period, maintenance services are provided with only component cost fees. We regularly follow up to ensure long-term stable operation of products.
