Key Features
75.7 x 75.7 x 30 mm Housing
The manufacturer's 75 mm blower series drawing identifies a 75.7 mm square housing outline with a 30 mm depth. Its mounting-hole and discharge geometry should be checked against the equipment.
2900 RPM Rated Speed
The Delta 75 x 75 x 30 mm series catalog specifies 2900 RPM for BFB0712H at the rated voltage under free-air measurement conditions.
11.30 CFM Airflow
The published maximum free-air flow is 11.30 CFM, and maximum static pressure is 0.480 inH₂O. These values are measured at separate operating endpoints of the performance curve.
Ball Bearing Construction
The manufacturer series drawing specifies ball bearings and UL 94 V-0 plastic frame and impeller materials. Its listed acoustical noise is 38.0 dB(A).
Base Two-Wire Connection
BFB0712H is listed with two power wires, red positive and black negative. Separately suffixed -F00 and -R00 versions have an additional wire for their respective monitoring functions.
Applications
- Industrial electronic enclosure cooling
- Compact power supply thermal management
- Embedded controller forced-air ventilation
- Telecommunications equipment cooling
- Computer and networking equipment ventilation
- Electronic instrumentation airflow management
- Equipment with side-discharge air passages
- Maintenance of compatible 12 VDC centrifugal blower assemblies

Frequently Asked Questions
What is Delta Electronics BFB0712H?
BFB0712H is a Delta Electronics 12 VDC brushless centrifugal blower. The base product is documented in the 75 x 75 x 30 mm series with ball bearings and a two-wire power connection.
Is BFB0712H an axial fan or centrifugal blower?
It is a centrifugal blower that directs airflow through a side outlet, rather than an axial fan that moves air straight through a square frame.
What supply voltage does BFB0712H require?
The manufacturer specifies 12 VDC nominal voltage and an operating voltage range of 7.0–13.8 VDC for the 75 x 75 x 30 mm series version.
What are the dimensions of BFB0712H?
The base model is listed with a 75.7 x 75.7 x 30 mm envelope. A separately documented BFB0712H-A in the 75 x 75 x 25 mm series has different dimensions, so the complete revision must be checked.
What is the rated input current?
The Delta 75 x 75 x 30 mm series table lists 0.22 A. The separate -A revision in the 75 x 75 x 25 mm series is listed at 0.27 A and should not be confused with this base model.
What is the rated power consumption?
The manufacturer lists 2.64 W at 12 VDC for BFB0712H in the 30 mm deep housing series.
What is the rated rotational speed?
The base 30 mm deep version has a published speed of 2900 RPM. A different -A series revision is listed at 4000 RPM.
What is the maximum airflow?
The 75 x 75 x 30 mm Delta series table specifies 11.30 CFM (0.320 m³/min) free-air flow. Actual installed airflow depends on the equipment air-path resistance.
What maximum static pressure is specified?
Delta lists 0.480 inH₂O (12.20 mmH₂O) at zero airflow. This is a different operating endpoint from the maximum free-air-flow rating.
What is the bearing type and noise rating?
The manufacturer specifies ball bearings and 38.0 dB(A) acoustical noise for BFB0712H in the 75 x 75 x 30 mm series.
Does BFB0712H have two or three wires?
The base BFB0712H is documented with two power leads. BFB0712H-F00 has an additional frequency or tachometer signal lead, while BFB0712H-R00 has an additional locked-rotor signal lead. Connector and signal wiring must be checked for the exact suffix.
What should be checked before ordering Delta BFB0712H?
Verify the full model and revision, 12 VDC supply, 0.22 A current, 75.7 x 75.7 x 30 mm housing, mounting points, discharge direction, 2900 RPM speed, 11.30 CFM airflow, bearing type, two-wire connection and any optional monitoring signal. Check carefully if the installed fan is marked BFB0712H-A, -F00 or -R00.
