Compact 40 mm server fan

The OEM Industries MMF-04C24DS ROP is a 40 mm by 15 mm axial fan built for inverter and server cooling. It runs on a 24 V supply drawing 0.09 A through a two-wire lead. The ball-bearing design targets continuous operation in industrial enclosures.

Two-pin install with polarity care

Connection uses a simple two-pin plug that fits standard 24 V headers. The bare leads carry no PWM or tach signal so speed control and monitoring are not possible. Reversing the wires will stall the motor, so verify polarity before powering the unit.

Suits 24 V industrial chassis

This fan fits maintainers refreshing inverter cabinets or ABB Fanuc gear that specify the 4015 form factor. Builders needing PWM control, 12 V operation or a three-wire feedback loop should look at a different model.
