The FB3G310-2AAL-90 is a high-capacity backward centrifugal EC fan designed for industrial ventilation and heavy-duty thermal management. Powered by a brushless EC motor (BLEC92) and featuring a large 310mm aluminum impeller, it delivers exceptional airflow (up to 2,250 m³/h) and static pressure (520 Pa) while operating on standard 230VAC power. Its rugged construction, wide voltage tolerance (184–270VAC), and compliance with CE, RoHS, and ErP2015 standards ensure reliability in demanding environments.
High-Volume Airflow with Precision Control
Engineered for large-scale cooling, it achieves 2,250 m³/h maximum airflow using a 6-blade aluminum impeller. Supports 0–10VDC/PWM speed modulation and provides tachometer output (FG signal) for real-time monitoring and system integration.
Industrial-Grade Durability
Operates across -25°C to 60°C with IP44-rated protection against dust/water ingress. Features ball bearings and die-cast aluminum housing for extended service life (50,000 hours L10) under continuous duty (S1).
Advanced Electrical Safety & Flexibility
Includes integrated +10VDC output (for control signal pull-up) and comprehensive protection: soft-start, reverse polarity lockout, and overvoltage/undervoltage/overheat shutdown. Compatible with 50/60Hz power systems globally.
Large HVAC Systems: Air handlers, ducted exhausts, commercial ventilation.
Industrial Machinery: Process cooling, ovens, drying systems.
Power Electronics: High-power inverters, transformer cooling.
Data Center Cooling: Server rack exhaust, hot-aisle containment.
Q: Can the +10VDC output directly power sensors?
A: No. It supplies max. 1.1mA for signal pull-up only; use with an external resistor for FG tachometer applications.
Q: Is PE (Protective Earth) connection mandatory?
A: Yes. Grounding via the green/yellow wire is critical for safety and EMI compliance.
Q: Does it support 110VAC operation?
A: No. The voltage range is strictly 184–270VAC (50/60Hz).
Q: Why only 6 impeller blades despite the large size?
A: The backward-curved design prioritizes efficiency and reduced turbulence at high airflow volumes.
