From ebm-papst, the Series 400 of DC axial fans are designed to deliver high performance while retaining a space saving size. This range of axial fans have sleeve bearings, which offer cost effective protection of the central shaft from environmental factors. This results in a simplified and economic design that is suitable for many thermal management applications.

With efficient brushless drives, and integrated communication electronics that prevent against reverse polarity, this series of fans are both reliable and easy to use.

• Low profile
• Low power consumption
• Air exhaust over struts
• Protected against reverse polarity and locking
• Integrated electronic communication
• Fibreglass reinforced plastic construction

These compact fans are ideal for installation in ACTA (Advanced Telecommunications Computing Architecture), which means they are suitable for a variety of applications.

• Cabinet Cooling
• Switch Networks
• Power Systems
• Telecom
• Medical
• Industrial

Q: What are the advantages of Sleeve Bearings fans over Ball Bearing fans?

A: While ball bearing fans can typically run for longer and in more harsh conditions than sleeve bearing, sleeve bearing have the advantage of having a simplified, often more cost effective design. Because of their simplified design, sleeve bearings are more impact resistance.

Q: Are these fans easy to use?

A: With simple screw installation, and with their necessary communication electronics integrated into the design, these DC axial fans are easy to install and operate.

Q: What are the advantages of this fan over competitors?

A: The compact and thin design of these fans makes them useful for low profile applications. Where space-saving is a concern, this model of fan is ideal.

Q: Are there accessories available for this fan?

A: There is a finger guard (251-081) available for this series of fans.
