AC4400FNNR ebm-papst AC4400FNNR Axial Fan | 120.7 CFM | Ball Bearing | 230VAC | UL/CE Certified

ebm-papst AC4400FNNR Axial Fan – high-performance axial fan engineered for superior cooling

The ebm-papst AC4400FNNR is a high-performance axial fan engineered for superior cooling and ventilation applications. Designed with durability and efficiency in mind, this fan features a ball-bearing motor, universal voltage compatibility (85-265VAC), and an impressive airflow of 120.7 CFM (3.38 m³/min). Its rugged fibreglass-reinforced plastic (PBTP) housing ensures reliability in demanding environments, while its compact 119 x 119 x 25mm form factor makes it easy to integrate into tight spaces.

Certified by UL, CE, CSA, EAC, VDE, and CCC, the AC4400FNNR meets stringent safety and performance standards. Its auto-restart function, thermal overload protection, and impedance-protected motor safeguard against electrical failures while maintaining consistent airflow under varying conditions. Ideal for HVAC systems, industrial enclosures, electronics cooling, and ventilation, this fan ensures long-term 60,000-hour L10 lifespan at 40°C (30,000 hours at max temperature).

Frequently Asked Questions (FAQ)

Q1: How does the AC4400FNNR compare to sleeve-bearing axial fans?

A: Unlike sleeve-bearing alternatives, the ball-bearing AC4400FNNR offers significantly longer lifespan (60,000 hours L10 at 40°C) and higher tolerance to mounting positions, making it ideal for vertical or horizontal installations.

Q2: Can this fan operate in high-humidity environments?

A: While not specifically IP-rated, its fibreglass-reinforced housing resists moisture corrosion. For extreme humidity, consider IP54-rated variants like the AC4400FNNR-IP54 (upon request).

Q3: Does the AC4400FNNR support speed control?

A: No, it’s a fixed-speed (4850 RPM) AC fan. For variable-speed needs, explore ebm-papst’s EC (electronically commutated) axial fan series instead.

Q4: What’s the static pressure capability of this fan?

A: It delivers 0.674 in H₂O (168 Pa) static pressure, suitable for overcoming moderate airflow resistance in ducted systems or enclosures.

Q5: Is thermal protection included?

A: Yes, it features built-in thermal overload protection, automatically restarting after cooling down from extreme conditions.

Q6: What’s the difference between AC4400FNNR and 4856ZW models?

Choose the AC4400FNNR for high-performance cooling needs or the 4856ZW for low-noise applications.

Conclusion

The ebm-papst AC4400FNNR is an industrial-grade axial fan offering high airflow, rugged construction, and compliance with international certifications. Its versatile voltage range and ball-bearing durability make it ideal for mission-critical cooling systems.
