The FK3G400-4AAL-80 is a high-power backward centrifugal fan engineered for extreme industrial environments demanding massive static pressure. Featuring a robust 400mm aluminum impeller and a heavy-duty BLEC188 EC motor, it delivers 12,600 Pa (5.04 in.wg) pressure—5× higher than standard centrifugal units—while moving 8,400 m³/h (4,943 CFM) of air. Built with an integrated support bracket and IP54-rated housing, it thrives in punishing conditions like foundries, chemical plants, and industrial ovens.
Industrial-Grade Pressure Powerhouse
Generates record 12,600 Pa static pressure—critical for dense filtration systems or long duct runs—via a backward-curved aluminum impeller and 2450 RPM operation. Handles 380VAC three-phase power with 2000W ±10% consumption.
Ruggedized Construction
All-aluminum components (impeller + housing) resist high heat (60°C continuous), while the reinforced bracket enables vibration-free mounting on machinery. IP54 sealing protects against abrasive dust and splashes.
Smart Control Integration
Supports 0–10VDC/PWM speed tuning and MODBUS-RTU protocol (via RSA/RSB wires) for seamless integration into automated industrial systems. Includes tachometer output (5 pulses/rev) for real-time diagnostics.
High-pressure industrial processes (furnaces, kilns, powder coating)
Heavy filtration systems (cement plants, mining operations)
Process ventilation (chemical reactors, exhaust scrubbers)
OEM heavy machinery cooling (compressors, hydraulic systems)
Q1: Why choose backward centrifugal over forward blades?
A1: Backward blades offer 20–30% higher efficiency at extreme pressures and handle dust/dense air better—ideal for industrial abuse.
Q2: Can it withstand temperatures above 60°C?
A2: No—prolonged exposure >60°C degrades electronics. For hotter environments, consult us for custom heat-shielded versions.
Q3: How does the bracket enhance stability?
A3: The welded steel bracket reduces vibration transfer by 70% versus bolt-on mounts, preventing fatigue failures in high-RPM applications.
