3110KL-05W-B50 - 80x80x25mm 8025 DC24V 0.12A 2-Lead Connectors Cooling Fan for CNC Robotics and Industrial Automation

The 3110KL-05W-B50 is an 80mm brushless DC axial cooling fan designed for variable-frequency drives, CNC controls, robotic controller cabinets, servo systems, PLC enclosures, power electronics and industrial automation equipment. Its ball-bearing construction, 24V operation and standard 80x80x25mm frame make it suitable for equipment repair where the original fan or matching electrical and mechanical specifications are required.

Conditional electrical and mechanical substitute: 8414N

Suffixes may identify different lead lengths, frame treatments, connector installations or equipment-specific harness configurations. Confirm the connector, wire length and polarity before substituting one suffix for another.

The current replacement-series fans have the same general 80x80x25mm 24V two-wire mounting class but may have slightly different airflow, power consumption and lead termination.

✅ Confirmed Compatibility

Compatibility depends on voltage, dimensions, mounting pattern, airflow requirement, lead configuration, connector and polarity. Different equipment revisions within the same product family may use different fans.

⚙️ Fit Notes

• Confirm that the original fan is rated for 24V DC. The similarly numbered 3110KL-04W-B50 is a 12V fan and is not electrically interchangeable.
• Verify the complete fan label whenever possible. The characters following B50 may identify a particular lead, connector or equipment configuration.
• Standard B50 versions use two power wires and do not provide a tachometer or locked-rotor output.
• Do not substitute a three-wire B59 version when the equipment requires a standard two-wire B50 fan unless the system wiring and monitoring circuit have been verified.
• Some equipment-specific versions use a two-pin plug, while standard component versions may have unterminated lead wires.
• Confirm the connector housing, terminal positions and polarity before applying power.
• If transferring the original connector, preserve the original red-positive and black-negative orientation.
• Confirm the 80x80x25mm frame dimensions and approximately 71.5mm mounting-hole spacing.
• Install the fan with the airflow arrow pointing in the same direction as the original fan.
• Maintain the original intake and exhaust orientation to avoid recirculating hot air inside the enclosure.
• Disconnect equipment from power and allow DC bus capacitors to discharge before servicing a drive, inverter or automation cabinet.
• The 08025SA replacement series is a documented successor family, but its airflow, current and connector may differ slightly. Verify system cooling requirements before substitution.
• Compatibility with an application category does not mean every model within that category uses this fan. Confirm the installed fan label or service parts information before ordering.
