Key Features
80 x 80 x 15 mm Slim Frame
The fan features an 80 mm square housing with a 15 mm depth. Delta's mechanical drawing shows 71.5 mm mounting-hole spacing, making mechanical fitment an important part of replacement selection.
2400 RPM Rated Speed
The published speed is 2400 RPM at rated voltage under free-air testing conditions. The AFB0812LB is a lower-speed member of Delta's 80 x 80 x 15 mm AFB family.
24.72 CFM Airflow
Delta's series table specifies 24.72 CFM maximum free-air flow and 0.087 inH₂O maximum static pressure. These are separate endpoints of the fan's pressure-airflow performance curve.
Ball Bearing Construction
The fan uses ball bearings and a plastic frame and impeller. Its manufacturer-published noise rating is 27.5 dB(A), with a reference weight of approximately 58 g.
Two-Wire Base Configuration
The unsuffixed AFB0812LB has two DC power leads and locked-rotor protection. Separately designated -F00 and -R00 versions include monitoring outputs and must be matched to the equipment wiring requirements.
Applications
- Industrial electronic enclosure ventilation
- Compact 12 VDC power supply cooling
- Embedded controller thermal management
- Telecommunications equipment airflow
- Industrial computer chassis ventilation
- Network switch and communications equipment cooling
- Electronic test and measurement instrument ventilation
- Maintenance of compatible 80 mm slim axial fan assemblies

Frequently Asked Questions
What is Delta Electronics AFB0812LB?
AFB0812LB is a Delta Electronics 12 VDC brushless axial cooling fan with an 80 x 80 x 15 mm housing, ball bearings and a two-wire electrical connection.
What is the rated voltage of AFB0812LB?
The manufacturer series specification and DigiKey list 12 VDC, with a permitted operating voltage range of 7.0–13.8 VDC.
What are the dimensions of AFB0812LB?
The frame measures 80 x 80 x 15 mm. Delta's series drawing identifies a 71.5 x 71.5 mm mounting-hole pattern with 4.5 mm diameter mounting holes.
What is the rated current?
Delta specifies 0.09 A at 12 VDC for the unsuffixed AFB0812LB. The same value appears in DigiKey's complete-model product specification.
What is the rated input power?
The manufacturer-published rated input power is 1.08 W.
What is the rotational speed?
The AFB0812LB has a rated speed of 2400 RPM. Actual speed can vary with applied voltage, operating conditions and manufacturing tolerances.
What is the maximum airflow?
Delta lists 24.72 CFM (0.700 m³/min) maximum free-air flow. DigiKey rounds the product airflow to approximately 24.7 CFM. Airflow in equipment depends on system resistance.
What is the maximum static pressure?
The maximum static pressure is 0.087 inH₂O (2.20 mmH₂O). This measurement occurs at zero airflow rather than at the maximum free-air-flow operating point.
What is the noise level?
The manufacturer specifies 27.5 dB(A), measured under controlled free-air acoustic testing conditions. Installed equipment noise may differ.
What bearing system does AFB0812LB use?
The fan uses ball bearings and plastic frame and impeller materials. DigiKey lists a reference life of 70,000 hours at 40°C, which is a specified test reference rather than a guaranteed service duration.
What is the difference between AFB0812LB, AFB0812LB-R00 and AFB0812L?
The unsuffixed AFB0812LB is a two-wire 80 x 80 x 15 mm fan. AFB0812LB-R00 has an additional locked-rotor signal lead. AFB0812L is a different 80 x 80 x 25 mm fan with a different airflow rating. These versions should not be substituted without checking their specifications.
What should be checked before ordering Delta AFB0812LB?
Confirm the full AFB0812LB part number and any suffix, 12 VDC supply, 0.09 A current rating, 80 x 80 x 15 mm frame, 71.5 mm mounting-hole spacing, 2400 RPM rated speed, 24.72 CFM free-air-flow requirement, two-wire termination and equipment compatibility.
