High Reliability Electric Compact Fans

 

Perseus high reliability electric compact fans are designed to meet the military standard. The military standard Perseus follows is the requirements of National Military Standard of China (GJB). The GJB is very stringent that it is exchangeable with the military standard of America in many areas. If you would like to make sure GBJ meets your need, send us your intended application scenario and detailed technical requirement and our technical team will assist you to verify our product meets your needs. Perseus's products have had years of data from frequent user and authoritative third-party, and we are confident that 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.

One of the important factors of a military grade fan is whether or not it could pass the wind pressure test, since the fan will bear a great amount of pressure when it is working. Perseus high reliability electric compact fans have successfully passed the wind pressure test. The goal of this experiment is to determine whether the equipment can keep the structure intact in high wind speed environment and work normally in high wind speed environment. This test is applicable to the evaluation of the equipment working in the open air such as mountains, coastal areas and islands, and the equipment placed and working on the open deck of ships. After testing, Perseus high reliability electric compact fans have no structural deformation or structural resonance resulting in damage, fastener and fixed bracket fracture, affecting the normal starting and rotating speed of radar antenna, aggravating the damage of rain, hail and frost to the equipment.

Perseus owns a full after-sales service team that will solve any customer's problem after purchasing. We have faith in our product, and with industry experience and reputation we will meet our customer's needs. Perseus is responsible for every single product created by us and will change it with cost if problem occurs (if problem occurs because of our product quality). In addition, Perseus provides free return and exchange for one year.
