Key Features
120 x 120 x 25.4 mm Frame
The axial fan has a 120 mm square housing and 25.4 mm depth. Delta's dimension drawing specifies a 105 mm square mounting-hole pattern with 4.5 mm diameter holes.
3400 RPM Reference Speed
The exact-model manufacturer approval specification identifies 3400 RPM reference speed at the rated supply voltage under its published test conditions.
113.11 CFM Maximum Airflow
Delta specifies 113.11 CFM maximum free-air flow and 0.430 inH₂O maximum static pressure. These values describe separate endpoints of the pressure-airflow performance curve.
Dual Ball Bearing Construction
The fan features two ball bearings and UL 94 V-0 plastic frame and impeller materials. Its published average acoustical noise is 46.5 dB(A), and the documented unit weight is 198 g.
Two-Wire Power Connection
The base AFB1224SH uses red positive and black negative DC power leads. The separately designated AFB1224SH-R00 adds a locked-rotor signal lead, while AFB1224SH-T500 has an IP55 protection rating.
Applications

Frequently Asked Questions
What is Delta Electronics AFB1224SH?
AFB1224SH is a Delta Electronics 24 VDC brushless axial cooling fan with a 120 x 120 x 25.4 mm frame, two ball bearings and two DC power leads.
What is the rated voltage of AFB1224SH?
The manufacturer approval specification identifies a nominal supply of 24 VDC and an operating voltage range of 14.0–27.6 VDC.
What are the dimensions of AFB1224SH?
The fan measures 120 x 120 x 25.4 mm. Delta's mechanical drawing specifies a 105 x 105 mm mounting-hole pattern and 4.5 mm diameter mounting holes.
What is the input current?
Delta specifies 0.28 A input current and a maximum specified current of 0.42 A. The manufacturer label drawing identifies 0.42 A as the maximum current marking.
What is the rated input power?
The exact-model manufacturer specification lists 6.72 W input power and a maximum value of 10.08 W.
What is the reference rotational speed?
Delta specifies 3400 RPM at rated voltage under the documented operating conditions.
What is the maximum airflow?
The maximum free-air flow is 113.11 CFM (3.203 m³/min), with a minimum specified value of 101.81 CFM. Installed airflow depends on equipment airflow resistance.
What is the maximum static pressure?
The maximum static pressure is 0.430 inH₂O (10.92 mmH₂O), with a minimum specified maximum-pressure value of 0.348 inH₂O. Maximum pressure and maximum free-air flow are separate operating conditions.
What is the specified noise level?
Delta lists 46.5 dB(A) average and 49.5 dB(A) maximum. Its manufacturer test procedure measures sound at a distance of one meter from the fan intake in free air.
What bearing system and materials are used?
The manufacturer specifies two ball bearings and UL 94 V-0 plastic for both the frame and impeller. The documented weight is 198 g.
Does AFB1224SH have two wires or a monitoring output?
The unsuffixed AFB1224SH uses two DC power leads, red positive and black negative, without a separate monitoring lead. The AFB1224SH-R00 is a distinct three-wire version with a locked-rotor signal. The AFB1224SH-T500 is a separately designated IP55 version.
What should be checked before ordering Delta AFB1224SH?
Confirm the complete AFB1224SH model number and any suffix, 24 VDC supply, 0.28 A input current and 0.42 A maximum, 120 x 120 x 25.4 mm frame, 105 mm mounting-hole spacing, 3400 RPM reference speed, 113.11 CFM airflow rating, two-wire termination and required environmental protection level.
