Important Note: If Noise Level is a more crucial issue than Extreme Cooling for your application, then this Fan is not suitable for your application. b-Blaster series and b-BlasterPWM series are designed for applications that require Intensive Cooling, heavy duty, and high performance. To achieve these requirements, it will require faster fan speed and a special fan motor and overall design. Please take note: Higher Speed (RPM) = Higher Airflow for Cooling (CFM) = Higher Noise Level (dBA).
Why Certifications are needed: Bluegears Inc believes all these certifications are necessary so that our products will perform safely and at the highest level for your applications. Therefore, all b-Blaster series and b-BlasterPWM series fans went through intensive lab tests and are certified by all the top test labs in the world to ensure the product quality, safety, perform at the highest level, and the materials are human and environmentally safe. UL, FCC, CE, RoHS, and REACH Certified.
