OEM Industries DB09225B48U 92mm Fan 48V .26A 4-Wire

Compact 92mm Cooling Fan

The OEM Industries DB09225B48U is a 92mm square DC fan built for system integrators and technicians who need a direct replacement for the AVC 9225 series. It operates on a 48V supply drawing 0.26A and uses a 4-wire interface for speed control and monitoring. The black frame and two-ball bearing suit industrial chassis or server enclosures where a standard 92mm mounting pattern is required.

Build Integration Requirements

This unit is a fan only, so it must be paired with a heatsink or duct that accepts a 92mm frame and provides the 48V PWM header. The four-wire connector frees the builder from voltage-only control and enables motherboard or fan-controller based curves. No LED lighting or additional accessories are included, keeping the assembly minimal for dense layouts.

Sustained Operation Behaviour

The two-ball bearing construction is rated for continuous duty at the specified 48V 0.26A input, maintaining consistent airflow without the wear patterns seen in sleeve alternatives. Under prolonged load the 4-wire feedback allows the host system to adjust speed dynamically, preventing thermal drift in tightly packed power cases. The DB09225B48U delivers stable cooling as long as the mounting surface and power delivery remain within design limits.
