Industrial 48 V case fan

The Delta FFB1248EHEBrand is a 120 mm by 38 mm axial fan designed for equipment that runs on a 48 V DC supply. It draws 0.75 A at 36 W and spins at 4 000 RPM to move 190 CFM of air. The unit targets integrators who need high static pressure in a compact frame.

Double ball bearing longevity

The double ball bearing construction reduces wear compared with sleeve alternatives, supporting continuous duty in industrial, medical or rail environments. No extra controllers or cables are bundled; the fan connects directly to a compatible 48 V rail. This simplicity suits rack builds where external fan controllers are already present.

26 V to 53 V input range

The wide voltage window lets the fan operate from nominal 48 V sources that may sag to 26 V or rise to 53 V under load. Standard 120 mm mounting holes fit common server and chassis patterns, while the 38 mm thickness requires a matching bay depth. Installers should verify clearance before ordering.

Întrebări despre acest articol

How often will the double ball bearing need replacement at 4000 RPM?

The double ball bearing is rated for continuous operation at 4000 RPM; typical service life exceeds several years under normal airflow conditions.

What thermal limit appears first when the fan runs at 36 W continuously?

The motor is designed for 48 V input up to 53 V; sustained 36 W draw stays within its thermal envelope without triggering protection.

How loud is 59 dBA when the fan operates all day in a rack?

At 59 dBA the noise is comparable to a quiet office; it remains constant at full 4000 RPM speed with 190 CFM airflow.
