Compact Centrifugal Blower

The OEM Industries FAL3F12LHST is a 50 mm centrifugal blower designed for tight enclosures such as projectors or small-form-factor systems. It operates on 12 V and draws 0.27 A through a three-pin power connector. The black housing contains a ball-bearing motor and no integrated lighting.

Direct 50 mm Replacement

This unit replaces an existing 5020-size blower that has worn bearings or insufficient airflow. The jump is worth it when the original fan develops audible rattle or when thermal throttling appears under sustained load. Builders needing a larger frame or higher static pressure must look elsewhere.

Steady-State Airflow Behaviour

Under continuous operation the ball bearing maintains consistent rotational speed without the wear-in period seen in sleeve alternatives. The centrifugal impeller delivers a focused airstream across heatsink fins rather than dispersing it broadly. Acoustic output remains stable over long sessions because the bearing preload does not shift with temperature.

Questions about this item

What are the exact dimensions of the FAL3F12LHST blower housing?

The blower measures 50mm by 20mm, matching the 5020 form factor for compact projector or small-form-factor cases.

How do I connect the three-wire lead to a motherboard header?

Align the 3-pin connector with the 12V fan header, matching the keyed tab to the missing pin, then press straight down until seated.

When should the ball-bearing blower be cleaned or replaced?

Inspect the intake every six months; if dust buildup reduces airflow or bearing noise appears, replace the unit.
