Since entering the HVAC industry in 2011, GFI HVAC has evolved from a trading company into a fully integrated manufacturer, continuously investing in advanced production facilities to expand our capabilities. This transformation has enabled us to develop extensive expertise in the manufacturing of air dampers, covering a wide range of types and applications in modern air duct systems.
Compared to fixed duct components, air dampers offer adjustable airflow control, enhanced system safety, and improved energy efficiency, making them essential components for modern HVAC systems. In addition, our flexible manufacturing allows for a wide variety of sizes, designs, and control options, supporting both standard and customized project requirements.
Our product portfolio includes a comprehensive range of air dampers designed for air supply, return, and exhaust systems in commercial and industrial HVAC projects. The product line covers:
Volume Control Dampers (VCD) - for regulating airflow and balancing duct systems.
Fire Dampers (FD) - for fire safety and compartment isolation.
Opposed Blade Dampers (OBD) - for precise air volume control.
Constant Air Volume (CAV) Dampers - for maintaining consistent airflow regardless of duct pressure variations.
Engineered to deliver both reliable performance and structural durability, our air damper solutions meet diverse project needs - whether focused on airflow regulation, fire protection, or intelligent air distribution control.
At GFI HVAC, we combine advanced production technology with a highly skilled workforce. With years of manufacturing experience and a team of experienced technicians, we ensure every damper is crafted with precision and care. Our manufacturing processes - from precision cutting, forming, and welding to final assembly - are supported by strict quality control, ensuring excellent sealing performance, smooth adjustment, and long-lasting durability.
We primarily manufacture our air dampers using galvanized steel, stainless steel, and aluminum materials, ensuring both strength and corrosion resistance.
GFI HVAC is committed to providing reliable and high-performance air damper solutions, backed by years of industry experience, skilled craftsmanship, and a dedication to manufacturing excellence. Whether you require standard models or customized designs, our comprehensive production capabilities ensure fast, accurate, and cost-effective delivery for your HVAC projects.
Since 2011, GFI HVAC has been dedicated to the HVAC industry, beginning with galvanized duct (GI duct) and pre-insulated duct manufacturing. Over the past 13 years, we have steadily expanded our operations, establishing and investing in new production facilities to enhance our capabilities.
Today, GFI HVAC operates three duct production line(GI Duct, Spiral Duct, PID Duct) and a dedicated manufacturing site for air vents and dampers. Additionally, we have strategically invested in rubber insulation and flexible duct factories, further strengthening our ability to provide integrated solutions for HVAC projects.
Beyond factories and workers, we also have well-established trade and logistics departments. In business management, GFI HVAC values humanity and shared beliefs. We firmly believe that GFI HVAC is not just a manufacturer but a company driven by human-centric values and a strong collective vision.
GFI HVAC provides advanced HVAC solutions to hospitals, factories, airports, stadiums, commercial complexes, and engineering contractors in over 50 countries worldwide. Additionally, GFI actively participates in international HVAC exhibitions in China, Thailand, Vietnam, and beyond, staying at the forefront of industry trends and fostering deep collaborations with global clients.
At GFI, we are more than just a manufacturer-we are your partner in building a sustainable and efficient future. Let's innovate together and create global value!
