Product Overview
The FB3G450-2AAY-30 is a high-performance backward-curved EC centrifugal fan designed for industrial ventilation and demanding airflow applications. Manufactured by Fanova (Suzhou) Motor Technology, it combines energy efficiency with robust construction. Driven by a brushless EC motor (Model BLEC137), it delivers up to 7,626 m³/h (4,487.9 CFM) airflow and 587 Pa (2.35 in.wg) static pressure while operating at 1450 RPM. Its IP54-rated housing and wide voltage range (184–270 VAC) ensure reliable operation in challenging environments.
Key Features
Smart Speed Control & Flexibility
Supports multiple control inputs: 0–10V DC, PWM, or RS485 (MODBUS). Includes a tachometer output (FG signal) for real-time RPM monitoring, enabling seamless integration into automated systems.
Built-in Protection & Reliability
Features comprehensive safeguards: soft-start protection, motor current limitation, over/under-voltage cutoff, locked-rotor detection, and thermal overload protection (for electronics and motor). Ensures longevity (50,000 hours L10 life) and fail-safe operation.
Industrial-Grade Durability
Constructed with a die-cast aluminum impeller, ball bearings, and corrosion-resistant coatings. Rated for continuous duty (S1) in temperatures from -25°C to 60°C and humidity up to 90% RH. Meets CE, RoHS, ErP2015, and ISO9001 standards.
Typical Applications
HVAC Systems: Large-scale air handling units (AHUs), ducted exhaust systems.
Industrial Machinery: Process cooling, dust/fume extraction, drying equipment.
Energy Recovery Systems: High-static-pressure ventilation in factories or warehouses.
Custom Enclosure Cooling: For electrical cabinets or machinery requiring IP54 protection.
FAQ
Q1: How do I connect the control wires for speed adjustment?
A1: Use the 0–10V/PWM (yellow wire) and GND (blue wire). For MODBUS, connect RSA (green) and RSB (purple). The +10V output (red wire) can power external sensors or serve as a pull-up reference.
Q2: Can it operate in high-temperature environments?
A2: Yes. The fan operates at up to 60°C ambient, while critical components (e.g., bearings, electronics) tolerate higher internal temps (80–115°C max).
Q3: What does the IP54 rating protect against?
A3: IP54 ensures resistance to dust ingress (limited) and water splashes from any direction, making it suitable for damp or dusty industrial settings.
Q4: Are custom cable lengths or protocols supported?
A4: Yes. Power cable lengths can be customized, and communication protocols (e.g., MODBUS alternatives) are adaptable—contact Fanova’s technical team for details.
