ebm-papst’s new 3250J series


Introducing ebm-papst’s new 3250J product series!

These new high-performance compact fans measure only 92 mm x 92 mm x 38 mm and are ideal for dissipating heat in limited space environments with lower system resistances.

The proven 3200J S-Force series of fans run at very high speeds to maintain performance against high system resistance. The 3250J S-Panther series extends this application range with fans designed specifically for lower system resistances, therefore operating at more moderate speeds.

Primary Advantages:  Decreased Noise with Increased Efficiency

Featuring an updated aeroacoustic impeller blade design with turbulator, the 3250J S-Panther series offers substantially improved acoustic characteristics. The sound power of the S-Panther is far lower than that of other fans, particularly in the higher frequency ranges starting at 1250 Hz. Operating at lower speeds, the S-Panther fans also achieve a 20-25% improvement in bearing life over the S-Force fans.

Potential Applications:

  • IT/Telecom
  • IT servers
  • IT network devices
  • Switch cabinets
  • Automation
  • Solar Inverters
  • Frequency Converters
  • Commercial Refrigeration
