Military Grade DC Centrifugal Fans

 

Perseus military grade DC centrifugal fans are produced to meet the highest standards possible. All requirements of National Military Standard of China (GJB) have been met by our products, and our fans can even go beyond on some areas. More detail can be provided upon request. After years of user experience and third-party testing, the product performance fully meets the requirements of temperature shock, acceleration, shock, vibration, heat, humidity electromagnetic compatibility, wide voltage start-up (-55°C), salt spray, fungus, damp heat and acid atmosphere.

Thanks to the unique design, Perseus military grade DC centrifugal fans can dissipate heat more efficiently compared to other centrifugal fans. When Perseus military grade DC centrifugal fans are working, the diffuser plays a big part. In the diffuser, the gas changes the air flow direction and the increase of the cross-section area of the pipeline slows down the air flow. This process will convert kinetic energy into pressure energy. During the process, the pressure increase mainly occurs in the impeller, followed by the expansion process. In a multistage centrifugal fan, a reflux device is used to make the air flow into the next impeller to generate higher pressure. Perseus military grade DC centrifugal fans are extremely powerful.

We believe complete after-sales service is essential and we pay close attention to customer satisfaction. Having spent years in this industry, Perseus has the reputation that few companies can have. The responsibility of us is to make sure every product purchased by customers is usable and meets the customer expectation. In addition, Perseus offers free return and exchange within one year.
