Fire Damper

Henan Shuangxin Fire Environmental Protection Equipment Manufacturing Co., Ltd. has been producing Fire Damper for more than 10 years. Henan Shuangxin attaches great importance to technology research and development in the process of development, and gradually cultivates a professional technical team, carefully designs each product, and does a good job in testing to ensure product quality. We have also established a modern workshop of more than 40,000 square meters, and are expanding new production plants to increase production capacity and meet the growing market size. The centrifugal fan is based on the principle of converting kinetic energy into potential energy, using a high-speed rotating impeller to accelerate the gas, then decelerate and change the flow direction, so that the kinetic energy is converted into potential energy (pressure). In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, the gas changes to the radial direction as it flows through the impeller, and then enters the diffuser. In the diffuser, the gas changes the direction of flow and the increase in the cross-sectional area of the duct slows down the gas flow, which converts kinetic energy into pressure energy. The pressure increase occurs mainly in the impeller, and secondly in the diffusion process. In a multi-stage centrifugal fan, a recirculator is used to move the airflow to the next impeller, creating a higher pressure. Henan Shuangxin has directly or indirectly exported many products all over the world. Now we are committed to opening up a larger market, and we welcome consumers to come to consult and discuss customized products. We can provide ODM and OEM.
