Delta BFB1012HH-A 12V DC Centrifugal Blower

The BFB1012HH-A is a 12V DC centrifugal cooling blower from Delta Electronics’ BFB series. It has an approximately 97.2 × 94.4 × 33mm rounded rectangular housing and uses a maintenance-free ball-bearing system.

Operating at up to 4,000 RPM, the BFB1012HH-A provides a maximum airflow of 34.28 CFM and maximum static pressure of 1.564 inchH₂O. Its centrifugal airflow design is suitable for directing cooling air through narrow ducts, heat sinks and confined equipment spaces where a conventional axial fan may not provide the required pressure or airflow direction.

The standard BFB1012HH-A uses two lead wires for power connection and does not include PWM control or tachometer feedback. 

Technical Specifications

Maximum airflow is measured near the free-air operating point, while maximum static pressure is measured near the blocked-flow point. The blower’s actual working airflow depends on the resistance of the equipment duct, heat sink, filter and outlet structure.

Typical Applications

The Delta BFB1012HH-A can be used in:

• Industrial computers and control equipment

• Network and telecom devices

• Server and storage-system cooling assemblies

• Power supplies and power-conversion equipment

• Projectors and display equipment

• Printers and imaging systems

• Electronic test instruments

• Battery charging equipment

• Automated production equipment

• Enclosures with narrow or directional airflow paths

Centrifugal Blower Design

Unlike an axial fan that moves air in a direction generally parallel to its rotating shaft, the BFB1012HH-A draws air through its inlet and discharges it through a side outlet. This arrangement makes the blower suitable for applications requiring directional airflow.

Its 39.70mmH₂O maximum static pressure can support airflow through restrictive cooling structures such as:

• Narrow ventilation ducts

• Densely spaced heat-sink fins

• Filtered air inlets

• Compact electronic enclosures

• Concentrated component hot spots

• Restricted side-outlet cooling channels

The blower outlet position and duct interface must match the equipment structure. A standard axial fan with similar airflow is generally not a direct mechanical replacement.

Electrical Interface

The BFB1012HH-A uses two lead wires for DC power:

• Positive power connection

• Negative power connection

This standard version does not provide a separate tachometer signal or PWM speed-control input. If the host equipment monitors fan speed or controls speed electronically, confirm whether a different BFB1012HH suffix version is required.

The power supply and connector should support the blower’s rated 1.25A current and startup requirements. Correct polarity must be verified before installation.

BFB1012HH-A Replacement Selection

Before replacing the BFB1012HH-A, confirm:

1. Complete part number: BFB1012HH-A

2. Rated voltage: 12V DC

3. Operating voltage range: 7.0–13.2V DC

4. Housing dimensions: 97.2 × 94.4 × 33mm

5. Rated current: 1.25A

6. Two-wire electrical interface

7. Air inlet and outlet positions

8. Mounting-hole locations

9. Connector type and wire length

10. Required airflow and static pressure

Blowers with similar dimensions may use different housing shapes, outlet locations, mounting holes, current ratings or control functions. These differences can prevent installation even when voltage and nominal size are the same.

The full suffix must be checked carefully. BFB1012HH-A and BFB1012HH-AF00 should not automatically be treated as identical, because suffix versions may use different wiring or monitoring functions.
