Key Features
80 x 80 x 25.4 mm Frame
The Delta EFB mechanical drawing gives an 80 mm square housing with 25.4 mm depth, 71.5 mm mounting-hole spacing and 4.5 mm mounting holes for fitment checks.
5000 RPM Reference Speed
Both the Delta EFB0812EH family table and model-specific -F00 parts listings identify 5000 RPM reference speed at rated supply voltage.
52.02 CFM Published Airflow
The Delta family table lists 52.02 CFM maximum free-air flow and 8.94 mmH₂O maximum static pressure. These are separate performance-curve endpoints.
Ball Bearing Construction
The manufacturer series drawing identifies ball bearings and UL 94 V-0 plastic frame and impeller materials. The series drawing lists a reference weight of 86 g.
Three-Wire Speed Feedback
The -F00 suffix denotes a frequency or tachometer signal. Complete-model suppliers list three leads; confirm the signal wire, connector orientation and circuit interface from the supplied unit.
Applications
- Industrial control cabinet forced-air cooling
- Variable-frequency drive equipment ventilation
- Power supply and inverter cooling assemblies
- Server chassis and industrial computing airflow
- Networking and telecommunications enclosure cooling
- Electronic instrument and control system ventilation
- Maintenance of compatible 12 VDC 80 mm axial fans
- Equipment with a matching three-wire fan speed-monitoring interface

Frequently Asked Questions
What is Delta Electronics EFB0812EH-F00?
EFB0812EH-F00 is a 12 VDC brushless axial fan in the Delta EFB 80 x 80 x 25.4 mm series. The -F00 functional suffix identifies a speed-feedback version.
What supply voltage does EFB0812EH-F00 require?
Complete-model supplier records specify 12 VDC. The Delta EFB0812EH family table lists a 7.0–13.8 VDC operating range; verify the full supplied fan approval specification for critical equipment.
What are the fan dimensions?
The Delta EFB series drawing shows an 80 x 80 x 25.4 mm frame with 71.5 mm mounting-hole pitch and 4.5 mm mounting holes.
Why are 0.28 A and 0.42 A both seen for this model family?
An older Delta EFB0812EH series table gives 0.28 A and 3.36 W, whereas multiple listings for the complete EFB0812EH-F00 fan show 0.42 A. These source-specific values should not be combined or treated as a single independently verified rated current.
What electrical power is associated with EFB0812EH-F00?
At the seller-listed 12 VDC and 0.42 A, calculated electrical power is 5.04 W. The older Delta EFB0812EH series table lists 3.36 W at 0.28 A; match the printed fan rating when selecting a power source.
What is the rated rotational speed?
The Delta EFB0812EH family table and complete-model -F00 product listings both identify 5000 RPM under stated rated-voltage conditions.
What is the maximum free-air flow?
The manufacturer EFB series table lists 52.02 CFM (1.473 m³/min) for EFB0812EH at zero static pressure. Installed flow varies with enclosure resistance.
What is the maximum static pressure?
The Delta series table reports 8.94 mmH₂O, approximately 0.352 inH₂O. Some -F00 resellers state 0.392 inH₂O. Use a matching manufacturer performance revision when pressure is a design-critical parameter.
What noise level is listed?
Complete-model -F00 suppliers commonly list 42.5 dB(A). A matching manufacturer approval sheet for this specific suffix was not confirmed for this acoustic value.
What type of bearing does the fan use?
Delta’s EFB 80 x 80 x 25.4 mm series drawing specifies ball bearings and UL 94 V-0 plastic frame and impeller materials.
What does the -F00 suffix mean, and how is it different from -R00?
In the Delta EFB series, -F00 designates a frequency or tachometer speed-feedback output, whereas -R00 designates a locked-rotor alarm output. These functions must not be exchanged without checking the equipment signal interface.
What should be checked before ordering EFB0812EH-F00?
Verify the complete EFB0812EH-F00 marking, 12 VDC supply, actual fan-label current, 80 x 80 x 25.4 mm dimensions, mounting hole pattern, 5000 RPM rating, three-wire connector, feedback signal pinout and system airflow requirements.
