Industrial-grade centrifugal blower

This CAFELE RL48-19/14 is a forward-leaning centrifugal fan built by ebm-papst for 24 V DC systems. It moves 28 m³/h of air at 4400 RPM while drawing 0.21 A and consuming 5 W. The 146 mm housing uses a ball-bearing motor rated for Protection Class III. It ships as a single unit weighing 0.075 kg.

Suited for tight 24 V enclosures

Engineers who need a compact blower for rack equipment, telecom chassis or industrial controllers will match the voltage and airflow profile. Builders working on standard 12 V desktop PCs or anyone needing a conventional axial case fan should look elsewhere.

24 V nominal voltage decides compatibility

The fan only operates from a 24 V DC supply; it will not start on 12 V lines found in typical ATX power supplies. Verify your system provides a 24 V rail before purchasing.

Questions about this item

What mounting hole spacing does the 146 mm frame require?

The forward-leaning centrifugal fan uses a 146 mm square frame; verify your chassis has matching hole centres before ordering.

How is the 24 V 0.21 A motor wired, and what polarity mistake do builders make?

Connect the two leads to a 24 V DC source — red to positive, black to negative — reversing them will prevent the ball-bearing motor from starting.

When should the ball bearing in this 4400 RPM blower be replaced?

The ball bearing is rated for continuous operation; replace the fan if airflow drops below 28 m³/h or audible rumble appears.
