REXNORD BACKWARD CURVED FANS (BCF series)

Rexnord BCF Series

1. High Static Pressure Capability

• Advantage: Unlike axial fans, which lose airflow when they hit resistance, the BCF series excels at pushing air through dense obstacles.

• Benefit: Ideal for Air Purifiers (HEPA filters), Fine-mesh Heat Exchangers, and Ducted Ventilation. It ensures that even as filters get dirty, the fan continues to move a reliable volume of air.

2. Space-Efficient Cooling

• Advantage: The air is discharged 90 from the intake.

• Benefit: Perfect for slim-profile electronics or 1U/2U rack servers where you need to suck air from the front and exhaust it out the side or top, rather than having a straight-through “wind tunnel.”

3. Non-Overloading Characteristic

• Advantage: The power curve of backward-curved blades is “self-limiting.”

• Benefit: Even if the air intake is completely blocked or the static pressure drops to zero, the motor will not draw excessive current and burn out. This makes it extremely safe and reliable in unpredictable industrial environments.

4. Quiet Efficiency

• Advantage: The aerodynamic shape of the backward blades produces less turbulence than axial blades.

• Benefit: Provides a lower noise-to-airflow ratio. It is often used in medical equipment, laboratory clean rooms, and high-end office projectors where high-pressure cooling is needed without the “jet engine” roar.
