Overview
The ebm-papst 3414N/39HH 24VDC axial fan is a reliable, compact cooling solution for industrial electronics, enclosures, and thermal-sensitive equipment. Designed for harsh environments with ball bearing construction and long service life, this fan operates continuously at 3250 RPM with minimal acoustic signature, making it suitable for control rooms, process automation, and sensor-driven applications where both performance and noise control matter.
Key Features
- Compact square footprint: 92 × 92 × 25.4 mm for easy mounting in tight enclosures
- Ball bearing design for extended bearing life and reliability in 24/7 operation
- Low noise: 38 dB(A) at nominal voltage—maintains quiet operation in industrial settings
- Wide voltage tolerance: 18–26 V DC allows operation on variadtors and unstable power supplies
- DC brushless motor: minimal maintenance and low electromagnetic interference
- Stranded wire termination (2-pin connector) simplifies installation
