Key Features
50 x 50 x 15 mm Housing
The compact square frame measures 50 x 50 x 15 mm. The manufacturer drawing shows 40 mm mounting-hole spacing and four mounting holes with a nominal diameter of 4.3 mm.
6400 RPM Reference Speed
The Delta exact-model specification identifies 6400 RPM reference speed at rated supply voltage, measured under the published operating conditions.
16.24 CFM Free-Air Flow
Maximum free-air flow is specified at 16.24 CFM and maximum static pressure at 0.315 inH₂O. These describe different endpoints on the pressure-airflow performance curve.
Ball Bearing Construction
The manufacturer and component distributors identify ball bearings and plastic frame and impeller materials. The published average acoustical noise is 36.0 dB(A).
Two-Wire Power Interface
The base AFB0524HHB has red positive and black negative power leads. Separate -F00 and -R00 variants provide different monitoring functions and must be selected using their complete part numbers.

What voltage does AFB0524HHB require?
The exact-model Delta specification identifies 24 VDC rated voltage and an operating range of 14.0–27.6 VDC.
What are the physical dimensions of AFB0524HHB?
The manufacturer drawing specifies a 50 x 50 x 15 mm frame, 40 mm mounting-hole spacing and four holes measuring approximately 4.3 mm in diameter.
What is the input current?
Delta lists 0.08 A nominal input current and a maximum specified input current of 0.12 A.
What is the input power of AFB0524HHB?
The manufacturer specifies 1.92 W input power, with a maximum value of 2.88 W at the documented operating conditions.
What is the rated rotational speed?
The Delta specification identifies 6400 RPM reference speed at rated voltage.
What is the maximum airflow?
AFB0524HHB is specified at 16.24 CFM (0.460 m³/min) maximum free-air flow. The minimum specified free-air-flow value is 14.48 CFM.
What is the maximum static pressure?
Delta specifies 0.315 inH₂O (8.00 mmH₂O) maximum static pressure at zero airflow, with a minimum specified maximum-pressure value of 0.253 inH₂O. Maximum airflow and pressure do not occur simultaneously.
What is the acoustical noise rating?
The manufacturer lists 36.0 dB(A) average and 39.0 dB(A) maximum under its defined free-air acoustic test conditions.
What bearing type does AFB0524HHB use?
Delta product information and major component distributors specify ball bearings. The fan uses plastic frame and impeller components and has an approximate weight of 32 g.
Does AFB0524HHB have two wires or a speed-feedback output?
The base AFB0524HHB is a two-wire fan, with red positive and black negative power leads. AFB0524HHB-F00 is a separately designated three-wire tachometer version, while -R00 provides a locked-rotor signal.
What should be checked before ordering Delta AFB0524HHB?
Confirm the complete part number and any optional suffix, 24 VDC supply, 0.08 A rated current and 0.12 A maximum, 50 x 50 x 15 mm frame, 40 mm mounting-hole spacing, 6400 RPM speed, 16.24 CFM airflow requirement, two-wire polarity and connector termination.
