Key Features
120 x 120 x 38 mm Frame
An aluminum-alloy frame measures 120 x 120 x 38 mm. The manufacturer drawing identifies 104.8 mm mounting-hole spacing and 4.5 mm holes.
2800 RPM Rated Speed
The complete-model ADDA datasheet specifies a rated speed of 2800 RPM ±10% under free-air conditions at the nominal voltage.
105.461 CFM Airflow
The manufacturer documents 105.461 CFM free-air flow, equivalent to 2.984 m³/min, with a static pressure rating of 0.265 inH2O.
Dual Ball Bearing Assembly
Uses two ball bearings, an aluminum-alloy frame and an impeller made from glass-filled PBT with UL 94 V-0 flammability classification.
Motor and Polarity Protection
Includes integrated motor protection and reverse-polarity protection. The two-wire connection uses red positive and black negative UL1007 AWG24 leads.

Frequently Asked Questions
What is ADDA AD1224HB-F51?
ADDA AD1224HB-F51 is a 24 VDC brushless axial cooling fan in the AD12038 series with a 120 x 120 x 38 mm frame, dual ball bearings and an aluminum-alloy housing.
What is the rated voltage of AD1224HB-F51?
The manufacturer specifies a 24 VDC nominal supply with an operating voltage range of 21.6-26.4 VDC.
What are the dimensions of AD1224HB-F51?
The fan measures 120 x 120 x 38 mm. The complete-model drawing identifies approximately 104.8 mm mounting-hole spacing and 4.5 mm diameter mounting holes.
What are the rated and actual current values?
The September 2013 ADDA complete-model datasheet specifies 0.32 A rated current and 0.26 A actual current. Older series tables may present 0.26 A without distinguishing these values.
What are the rated and actual power values?
The same manufacturer datasheet specifies 7.68 W rated power and 6.24 W actual power for the documented configuration.
What is the rated speed of AD1224HB-F51?
The ADDA manufacturer lists 2800 RPM ±10% at the rated voltage in free air.
What is the airflow of AD1224HB-F51?
The complete-model datasheet lists 105.461 CFM (2.984 m³/min) free-air flow, with a specified minimum of 94.914 CFM. Actual airflow depends on installed system resistance.
What is the static pressure rating?
The manufacturer identifies 0.265 inH2O, equivalent to 6.731 mmH2O, under its specified test conditions.
What bearing type does AD1224HB-F51 use?
The manufacturer documentation marks the two-ball-bearing configuration for this model.
What is the documented noise level?
The manufacturer specifies 46.7 dB(A), with a maximum of 50.7 dB(A), measured under its stated noise test conditions.
How is AD1224HB-F51 connected?
The manufacturer drawing shows two UL1007 AWG24 power leads, 280 ±10 mm long. Red is positive and black is negative. The datasheet also identifies reverse-polarity protection.
What should be checked before ordering ADDA AD1224HB-F51?
Verify the complete model number, 24 VDC supply, current and power ratings, 120 x 120 x 38 mm dimensions, mounting pattern, cooling demand, two-wire connections and any revision-specific differences against the installed equipment.
