The Trusted Source for Durable Cooling Fans

133mm Centrifugal Fan Manufacturer

High-static pressure 133mm centrifugal blower — purpose-built for electrical cabinets, telecom shelters, inverters, and industrial control systems.

133mm centrifugal fan

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.

FAQ of AC Centrifugal Fan Manufacturer

What is the difference between a centrifugal fan and an axial fan?
Centrifugal fans generate higher static pressure and are more efficient when cooling through filters, narrow ducts, or densely packed components. Axial fans move high volume at low pressure – our 133mm centrifugal is the choice for restricted systems.
First, verify mounting dimensions (133mm frame). Then match airflow and static pressure against system impedance curve. Our team can guide you using your cabinet specs.
We offer 12V, 24V, 48V DC and even 110/220V AC customization for large projects. Lead time for custom samples: 2~3 weeks.
Please provide: application, required voltage, available mounting space, target airflow or pressure, and operating ambient temperature.
Yes, designed specifically for electrical enclosures, inverter cooling, and industrial control panels. High static pressure ensures air reaches hot spots.
Samples: 3~7 days for standard models, 15 days for custom. Bulk order (1k+ pcs): 25~35 days depending on customization.
