Centrifugal Fan
BC225 Series
Applications
The core advantages of EC/DC/AC backward-curved centrifugal fans are: high static pressure, high airflow, adjustable speed, energy efficiency, low noise, and suitability for continuous operation. Therefore, they are mainly used in HVAC and industrial ventilation scenarios that require ducted air supply, variable air volume control, and overcoming relatively high system resistance.

FAQ

Why DC225 backward-curved centrifugal fan is a Standard in Telecom & IT for 48V DC power systems?
telecom and IT infrastructure is one of the primary applications for a DC225 backward-curved centrifugal fan—especially models designed for 48V DC power systems.
A 225mm impeller size combined with a DC/EC outer-rotor motor delivers high airflow (typically 1,000–1,500 m³/h) and strong static pressure in a compact footprint, making it ideal for densely packed electronics.
Why DC225 is a Standard in Telecom & IT
Native 48V DC Bus Compatibility: Telecom base stations and battery backup systems operate natively on 48V DC power. A 48V DC225 fan runs directly off the battery/rectifier bus without needing AC inverters or extra step-down converters.
High Static Pressure Performance: Telecom cabinets and server racks are tightly packed with PCBs, heat sinks, and dust filters. The backward-curved design pushes air through high airflow resistance without stalling.
Outer-Rotor Space Saving: The motor sits inside the impeller hub, minimizing axial depth so more space is available for electronic components.
Precision Speed Control (PWM / 0-10V / Modbus): Allows the cabinet controller to dynamically scale fan speed based on ambient temperature, cutting power consumption during off-peak hours or cooler nights.
Key Telecom & IT Equipment Using DC225 Fans
Outdoor Telecom Cabinets / BTS (Base Transceiver Stations): Primary heat extraction for 4G/5G radio equipment, rectifiers, and outdoor battery enclosures.
Energy Storage Systems (ESS) & Telecom UPS: Cools high-capacity lithium battery racks and power conversion systems.
In-Row Air Conditioners & CRAC Units: Deployed in small data centers and edge computing nodes to pull hot exhaust air directly from server racks.
High-Power Rectifier & Inverter Cabinets: Dissipates heat generated by AC-to-DC power conversion units inside telecom switching centers.
