Key Features
40 x 40 x 20 mm Axial Frame
The compact square frame measures 40 x 40 x 20 mm. Check the mounting geometry and space around the fan against the equipment design.
8200 RPM Reference Speed
Delta specifies 8200 RPM as the reference rotational speed of this exact -R00 model under the stated operating conditions.
9.43 CFM Free-Air Performance
The manufacturer lists 9.43 CFM maximum free-air flow and 0.354 inH₂O maximum static pressure. These are separate operating-curve endpoints.
Dual Ball Bearings
The fan uses two ball bearings, with UL 94 V-0 plastic frame and impeller components. Delta publishes a 30.5 dB(A) average acoustic reading.
Three Leads with Lock Signal
Delta documents red positive, black negative and blue lock-signal wires for the -R00 suffix. The blue lead is a locked-rotor status signal, not a stated PWM or tachometer connection.
Applications
- Compact industrial control enclosure ventilation
- Embedded electronic equipment cooling
- Industrial power supply cooling assemblies
- Electronic instrumentation thermal management
- Communications equipment ventilation
- Small power electronics enclosure airflow
- Equipment requiring a locked-rotor status signal
- Maintenance of compatible 12 VDC 40 mm axial fan systems

Frequently Asked Questions
What is Delta Electronics EFB0412HHD-R00?
EFB0412HHD-R00 is a Delta Electronics 12 VDC brushless axial fan with a 40 x 40 x 20 mm frame, two ball bearings, and a three-wire connection including a locked-rotor signal.
What voltage does EFB0412HHD-R00 use?
The Delta manufacturer specification lists a 12 VDC rated voltage and a 7.0–13.8 VDC operating range. It also specifies a starting voltage of no more than 5.0 VDC at 25°C.
What are the dimensions of EFB0412HHD-R00?
The fan has a 40 x 40 x 20 mm frame. Check mounting-point geometry and electrical lead routing against the equipment before ordering.
What is the rated input current?
The manufacturer specifies 0.10 A input current with a maximum of 0.15 A. These figures should be kept distinct when evaluating a power supply.
What input power does the fan require?
Delta specifies 1.20 W input power with a maximum of 1.80 W at the stated electrical operating conditions.
What rotational speed is specified for EFB0412HHD-R00?
The manufacturer lists 8200 RPM as the reference speed for the complete EFB0412HHD-R00 part number.
What is the maximum airflow?
The manufacturer specifies 9.43 CFM (0.267 m³/min) free-air flow, measured at zero static pressure. Actual airflow decreases as system resistance increases.
What is the maximum static pressure?
The maximum static pressure is 0.354 inH₂O (9.00 mmH₂O), specified at zero airflow. This should not be combined with the maximum free-air flow as one operating point.
What is the noise rating?
Delta lists 30.5 dB(A) average acoustic noise and a specified maximum of 34.0 dB(A), measured under its documented conditions.
What bearing system does EFB0412HHD-R00 use?
The manufacturer specification identifies two ball bearings and UL 94 V-0 plastic frame and impeller materials.
What does the -R00 suffix mean for wiring?
For this complete model, Delta documents three UL1061-F AWG24 leads: red positive, black negative, and blue lock signal. Do not mistake the lock signal for a PWM control or tachometer output.
What should be checked before ordering EFB0412HHD-R00?
Verify the full EFB0412HHD-R00 model marking, 12 VDC supply, 0.10 A input current with 0.15 A maximum, 40 x 40 x 20 mm frame, mounting arrangement, airflow requirements, three-wire pinout and blue locked-rotor signal function.
