Military Grade DC Brushless Fans

 

Perseus military grade DC brushless fans are developed and manufactured in strict accordance with the requirements of National Military Standard of China (GJB). 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.

According to the different action principle of a fan, there are two types of fan: vane type and volumetric type. Vane type is to transfer energy to gas through impeller rotation; volumetric type is to transfer energy to gas through periodic change of chamber volume. The two types of fans have different forms. For example, the vane type is divided into axial flow fan, centrifugal fan and mixed flow fan. In this case, Perseus military grade DC brushless fan is an axial flow fan, whose air flow is in the same direction as the axis of the vane. This type of fan has the advantage of low power consumption, fast heat dissipation, low noise, energy-saving and environmental friendly.

Complete after-sales service, years of industry experience and reputation make Perseus responsible for every product purchased by customers. Perseus offers free return and exchange within one year.
