Product Advantages
Excellent High and Low Temperature Resistance
Circular Fire Damper utilizes a 2mm thick cold-rolled steel plate for its valve body frame, ensuring a sturdy construction and outstanding high-temperature resistance. The product operates stably within a wide temperature range of -40°C to +95°C (or -50°C to +300°C for specific models), demonstrating remarkable low-temperature adaptability and high-temperature tolerance. This is attributed to the precise material selection and manufacturing process, allowing Circular Fire Damper to maintain excellent fire protection performance under extreme climatic conditions.
Efficient Waterproofing and Durable Structure
The blades are made of 1.5mm thick galvanized cold-rolled corrugated sheet, connected by spot welding to form a sturdy and waterproof structure. The galvanized layer enhances both the corrosion resistance of the blades and the overall waterproof performance. Combined with precise sealing design, Circular Fire Damper boasts a leakage air volume of less than 2%, significantly lower than industry standards, effectively preventing the ingress of moisture and humidity, ensuring long-term durability.
High Strength and Stability
The blade shafts and connecting rods are made of 45# steel with galvanized passivation, specifically 12x12 square shafts or 11.5 cold-drawn round shafts, and 14x3 pressed connecting rods. These components possess high strength and excellent mechanical properties. With a maximum allowable torque of 34Nm, they ensure stability and durability during frequent opening and closing of the blades. This design enables Circular Fire Damper to withstand high mechanical stress and extend its service life.
High-Precision Sealing and Low Air Leakage
Circular Fire Damper employs high-precision sealing technology, combined with precise installation processes and advanced seal strip designs, achieving a leakage air volume of less than 2%. This performance surpasses similar products, effectively preventing the diffusion of smoke and harmful gases, enhancing the fire safety of buildings.
Easy Installation and Maintenance
Thanks to its modular design and straightforward installation process, Circular Fire Damper can be easily installed without complex tools or professional skills. Additionally, its sturdy structure and easy-to-disassemble design facilitate maintenance, allowing users to perform cleaning or part replacement with simple operations, reducing maintenance costs and time.
