Product Overview: 133mm Centrifugal Fan / Blower
A centrifugal fan (also known as a radial blower) draws air axially into the impeller and discharges it perpendicularly, generating significantly higher static pressure than axial fans. This makes it the ideal choice for equipment cooling with restricted airflow paths, high component density, or long duct runs.

Why industrial equipment relies on centrifugal fans: Our 133mm size offers the perfect balance between compact footprint (133mm frame) and powerful airflow up to 150 CFM. Unlike conventional axial fans that struggle against backpressure, our centrifugal series maintains stable cooling performance inside crowded cabinets, power supplies, and telecom shelters. For engineers seeking reliability under 24/7 operation, our ball-bearing design and thermal protection ensure longevity.
