Key Features
40 x 40 x 20 mm Frame
The documented fan features a 40 mm square frame with a 20 mm depth, providing a compact cooling format for equipment with limited mounting and ventilation space.
2.0 W Rated Power
Multiple replacement-part listings identify a 2.0 W rating for PMD2404PKB3-A.(2).B4422.GN. A detailed supplier specification also lists 0.083 A current at a nominal 24 VDC supply.
8200 RPM Supplier-Listed Speed
The (2).B4422.GN configuration is commercially listed at 8200 RPM with 10.8 CFM airflow. These performance figures should be verified against the exact supplied fan for engineering-critical applications.
Dual Ball Bearing Construction
The detailed replacement specification identifies a dual ball bearing design with PBT thermoplastic frame and impeller materials. The supplier-reported acoustical noise level is 36 dB(A).
Two-Wire Electrical Connection
The documented (2).B4422.GN configuration uses two DC power leads. Confirm wire polarity, termination, connector compatibility and available installation clearance before connecting the fan to the equipment.
Applications
- Compact industrial inverter cooling
- Industrial drive electronics ventilation
- Server power supply cooling assemblies
- Network switch and communication equipment ventilation
- Compact industrial controller cooling
- Embedded electronics thermal management
- Electronic enclosure forced-air cooling
- Replacement of compatible 40 mm 24 VDC axial cooling fans

Frequently Asked Questions
What is SUNON PMD2404PKB3-A?
PMD2404PKB3-A is a SUNON PMD-series DC brushless axial cooling fan. The documented (2).B4422.GN configuration is listed for compact industrial and electronic equipment cooling.
What is the rated voltage of PMD2404PKB3-A?
Commercial listings for PMD2404PKB3-A.(2).B4422.GN specify a nominal supply voltage of 24 VDC.
What are the dimensions of PMD2404PKB3-A?
The documented (2).B4422.GN configuration measures 40 x 40 x 20 mm. Check the complete suffix and fan housing because a separate base-model commercial listing identifies a different frame depth.
What is the rated current?
A detailed supplier specification lists 0.083 A for PMD2404PKB3-A.(2).B4422.GN. Confirm this value against the marking on the actual fan.
What is the rated power consumption?
Multiple commercial listings identify 2.0 W for the documented (2).B4422.GN configuration. A separate listing advertises a 4.1 W version, which should not be treated as electrically identical without verification.
What is the rated fan speed?
A specialist replacement-part supplier lists 8200 RPM for PMD2404PKB3-A.(2).B4422.GN. An independent manufacturer speed specification for this complete suffix was not established.
What airflow does PMD2404PKB3-A provide?
The documented (2).B4422.GN replacement configuration is listed at 10.8 CFM, approximately 18.3 m³/h. Confirm this figure if the cooling design requires a specified airflow capacity.
What is the static pressure rating?
A detailed supplier listing identifies 0.35 inH2O, approximately 87.2 Pa, for (2).B4422.GN. A manufacturer performance curve for this exact configuration was not independently located.
What bearing system does PMD2404PKB3-A use?
The documented (2).B4422.GN version is listed with a dual ball bearing system. Bearing construction should be verified for other suffix configurations.
What is the acoustical noise level?
A specialist supplier lists 36 dB(A) for the (2).B4422.GN configuration. Actual installed noise depends on airflow restriction, mounting conditions and the complete fan version.
How many wires does PMD2404PKB3-A have?
Multiple independent replacement listings describe the (2).B4422.GN configuration as a two-wire DC fan. A generic description on one supplier page mentions four wires, but its detailed product specification identifies two wire leads. The actual wiring and connector should therefore be checked before installation.
What should be checked before ordering PMD2404PKB3-A?
Confirm the complete SUNON model number including the (2).B4422.GN suffix, 24 VDC supply, 2.0 W power rating, 0.083 A listed current, 40 x 40 x 20 mm dimensions, dual ball bearing, mounting-hole positions, electrical polarity, connector termination, airflow direction and equipment cooling requirements. Do not assume that another PMD2404PKB3-A assembly with different depth, power or wiring is directly interchangeable.
