Compact 45mm blower for tight spaces

The OEM Industries BM4515-04W-B59 is a 45mm DC blower designed for projector printers and similar compact equipment. Its small footprint suits builds where a standard axial fan will not fit. The three-pin connector provides basic speed reporting without PWM control.

Ball-bearing motor runs on 12V 0.25A

The blower draws 0.25A at 12V through a three-wire lead. Ball bearings reduce friction for consistent airflow in continuous operation. No LED lighting is fitted, keeping the unit suitable for professional or industrial environments.

Mounts directly to 45*15mm cut-outs

Installation requires a 45mm by 15mm opening and a three-pin header capable of supplying 12V. The blower format exhausts air through a focused outlet, freeing surrounding space that a radial fan would occupy. Ensure the target device accepts a 4515-size blower before purchase.

Questions about this item

How do I install the 45mm blower fan using the 3-pin connector?

Align the three pins with the motherboard or controller header, press straight down until the latch clicks, and route the wires so the blower exhaust faces the heatsink fins — the common mistake is plugging the connector in offset by one pin.

What maintenance will the ball-bearing blower need over time?

The ball bearing is sealed and does not require lubrication; if airflow drops, remove dust from the 45mm impeller and housing with compressed air — replacement is only needed if the bearing becomes noisy or the fan stops spinning.

At what point does the 12V 0.25A blower hit its thermal limit during sustained use?

The blower draws a constant 0.25 A at 12 V, so its own heating stays low; the practical limit appears when the component it cools can no longer transfer heat into the 45×15 mm airstream, causing exhaust temperatures to rise.
