Key Features
40 x 40 x 20 mm Frame
The square 40 mm frame has a depth of 20 mm, providing axial airflow for electronic equipment designed around this mounting format.
9000 RPM Reference Speed
The manufacturer specification lists 9000 RPM as the reference speed for the complete EFB0412VHD model under nominal operating conditions.
10.10 CFM Free-Air Flow
Delta specifies 10.10 CFM maximum free-air flow and 0.416 inH₂O maximum static pressure. These ratings refer to separate endpoints of the fan performance curve.
Dual Ball Bearing Assembly
EFB0412VHD incorporates two ball bearings with a plastic frame and impeller classified UL 94 V-0. The published average acoustic noise rating is 32.5 dB(A).
Two-Wire Power Connection
The base EFB0412VHD has two UL1007-F AWG24 leads: red positive and black negative. Separate -F00 and -R00 versions use an additional lead for different monitoring functions.
Applications
- Compact industrial control equipment ventilation
- Embedded electronics forced-air cooling
- Industrial power supply cooling assemblies
- Telecommunications equipment thermal management
- Electronic instrumentation enclosure airflow
- Small power electronics system ventilation
- Computer and networking hardware cooling assemblies
- Maintenance of compatible 12 VDC 40 mm axial fan systems

Frequently Asked Questions
What is Delta Electronics EFB0412VHD?
EFB0412VHD is a Delta Electronics 12 VDC brushless axial cooling fan with a 40 x 40 x 20 mm frame, two ball bearings and a reference speed of 9000 RPM.
What is the rated voltage of EFB0412VHD?
The manufacturer specifies 12 VDC rated voltage and an operating voltage range of 7.0–13.8 VDC.
What are the dimensions of EFB0412VHD?
The fan measures 40 x 40 x 20 mm. Verify mounting-hole positions, fan thickness and enclosure clearance against the equipment installation.
What is the input current of EFB0412VHD?
The manufacturer specifies 0.12 A input current, with a maximum specified value of 0.18 A.
What is the input power rating?
Delta specifies 1.44 W input power, with a maximum of 2.16 W at the stated operating conditions.
What is the rated fan speed?
The manufacturer lists 9000 RPM as the reference rotational speed for the complete EFB0412VHD model.
What is the maximum airflow?
The Delta specification lists 10.10 CFM (0.286 m³/min) maximum free-air flow and 9.25 CFM as the minimum specified free-air value. Actual airflow depends on system resistance.
What is the maximum static pressure?
The manufacturer specifies 0.416 inH₂O (10.57 mmH₂O) maximum static pressure at zero airflow. This is not the pressure available at the maximum free-air flow operating point.
What is the acoustical noise rating?
Delta lists 32.5 dB(A) average noise and a maximum specified value of 36.0 dB(A), measured under the documented test conditions.
What bearing system does EFB0412VHD use?
The manufacturer specifies two ball bearings, a UL 94 V-0 plastic frame and a UL 94 V-0 plastic impeller.
Does EFB0412VHD have two or three wires?
The base EFB0412VHD has two power leads, red positive and black negative. EFB0412VHD-F00 is a separate three-wire version with a speed sensor, while EFB0412VHD-R00 has a locked-rotor signal. Verify the complete model suffix before substituting one version for another.
What should be checked before ordering Delta Electronics EFB0412VHD?
Confirm the complete EFB0412VHD marking, 12 VDC supply, 0.12 A current rating, 40 x 40 x 20 mm frame dimensions, mounting arrangement, 9000 RPM reference speed, 10.10 CFM airflow requirement and two-wire power connection. Check any additional suffix against its own electrical specification.
