Compact 36 mm frame fan

The AVC DB03628B12S is a 36 × 36 × 28 mm centrifugal fan built for tight equipment bays. It runs on 12 V DC and draws 0.80 A through a four-wire interface. Double ball bearings give a maintenance-free design suited to continuous duty in medical, rail, industrial and new-energy vehicle gear. Buyers needing a larger airflow path or a standard 120 mm mounting pattern should look elsewhere.

Verify voltage and mounting holes

Confirm the system supplies 12 V DC and can deliver 0.80 A on the fan header before ordering. The 36 mm square footprint and 28 mm depth require matching cut-outs and screw spacing; no adapter brackets are included. The four-wire lead supports PWM control, so check that the controller or motherboard header uses the same pin-out. Installations in vibration-heavy rail or drive cabinets should allow for secure fastening.

Four-wire lead enables speed control

The bundled four-wire cable adds PWM speed regulation and tachometer feedback without extra parts. Double ball bearings remove the need for periodic lubrication, cutting long-term service effort in sealed enclosures. No mounting screws, filters or software utilities are supplied in the package.

Questions about this item

Does the DB03628B12S come with mounting screws or a power cable, or do I need to buy them separately?

The fan ships as a single 36 × 36 × 28 mm unit with a 4-wire lead; mounting hardware and any extension cables are not included.

The supplier lists many AVC model numbers — how do I know this DB03628B12S is the right one for my 12 V application?

This model is specified for DC 12 V at 0.80 A with a 4-wire interface and double ball bearings; match those electrical and mechanical details to your device's requirements.

What does the 0.80 A current draw mean for actual cooling performance inside my chassis?

At 12 V the fan draws 0.80 A, delivering high air volume and wind pressure through its 36 mm frame, suitable for targeted component or small-enclosure cooling.
