Key Features
120 x 120 x 25.4 mm Frame
The square 120 mm frame has a 25.4 mm depth. Verify mounting-hole alignment, enclosure clearance and the airflow direction when selecting a replacement cooling fan.
3100 RPM Fan Speed
The Delta manufacturer specification identifies 3100 RPM as the reference rotational speed for AFB1212VH under its stated operating conditions.
103.75 CFM Free-Air Flow
The manufacturer specifies 103.75 CFM maximum airflow at zero static pressure and 0.371 inH₂O maximum static pressure at zero airflow. Actual system airflow depends on installation resistance.
Dual Ball Bearing Assembly
AFB1212VH uses two ball bearings with UL 94 V-0 plastic frame and impeller components. Delta specifies an average acoustical noise level of 44.5 dB(A).
Two-Wire Power Connection
The manufacturer specifies UL1007-F AWG24 leads, with a red positive wire and a black negative wire. The fan also incorporates locked-rotor protection described in its product specification.
Applications
- Industrial control cabinet forced-air cooling

Frequently Asked Questions
What is Delta Electronics AFB1212VH?
AFB1212VH is a Delta Electronics DC brushless axial cooling fan with a 120 x 120 x 25.4 mm frame, a 12 VDC rated supply and a two-ball-bearing system.
What is the rated voltage of AFB1212VH?
The manufacturer specifies a rated voltage of 12 VDC and an operating voltage range of 7.0–13.8 VDC.
What are the dimensions of AFB1212VH?
The fan measures 120 x 120 x 25.4 mm. Before replacement, compare the mounting-hole locations and installation clearance with the existing fan.
What input current does AFB1212VH require?
The Delta specification lists 0.40 A input current, with a maximum specified current of 0.60 A at the rated voltage.
What is the input power of AFB1212VH?
The manufacturer lists 4.80 W input power, with a maximum specified value of 7.20 W.
What is the rated rotational speed?
Delta lists 3100 RPM as the reference rotational speed. Actual rotational speed may vary with operating conditions.
What is the maximum airflow of AFB1212VH?
The manufacturer specifies 103.75 CFM, equivalent to 2.938 m³/min, at zero static pressure. The minimum specified free-air airflow is 93.37 CFM.
What is the maximum static pressure?
Delta specifies 0.371 inH₂O, equivalent to 9.43 mmH₂O, at zero airflow. This endpoint rating should not be interpreted as the pressure available at maximum airflow.
What noise level is specified?
The manufacturer lists an average acoustical noise level of 44.5 dB(A) and a maximum specified value of 47.5 dB(A), measured under its stated test conditions.
What type of bearing does AFB1212VH use?
The manufacturer specifies two ball bearings. The frame and impeller are made from UL 94 V-0 plastic.
How many wires does AFB1212VH have?
The manufacturer's AFB1212VH specification identifies two UL1007-F AWG24 lead wires: red for positive (+) and black for negative (-). The base model is not documented with a separate tachometer or PWM lead.
What should be checked before ordering Delta Electronics AFB1212VH?
Confirm the complete AFB1212VH model marking, 12 VDC supply, 0.40 A input current, 120 x 120 x 25.4 mm dimensions, mounting pattern, 103.75 CFM airflow requirement, two-wire connection and the fan's operating environment. Compare any additional suffix against the corresponding Delta specification before substitution.
