Aviary fan Recirculation Fan 52''

for livestock buildingsfor pig farm buildingsdairy farm

Product overview
The 52-inch recirculation fan is designed for livestock ventilation to reduce heat stress and improve barn climate uniformity. The unit pairs an Electronically Commutated (EC) motor with a beltless direct-drive system to remove common wear points and lower maintenance interventions. An integrated Variable Frequency Drive (VFD) enables continuous variable speed control for precise airflow management and reduced acoustic emissions within animal housing.

Key benefits

• Maintenance-free direct-drive assembly (no belts)
• Energy-saving variable speed control via integrated VFD
• Reduced acoustic emissions to limit animal stress
• High-efficiency airflow for wide-area distribution

Technical specifications

• Fan dimension: 52-inch diameter housing optimized for wide-area air distribution
• Motor technology: Electronically Commutated (EC) motor with advanced direct-drive system
• Airflow capacity: Stable performance up to 22,868 CFM
• Efficiency rating: 18.1 CFM/W (30.8 m³/h/W)
• Speed control: Integrated Variable Frequency Drive (VFD), nominal speed 410 RPM
• Power configurations: Single-Phase 180–277 V and Three-Phase 360–460 V options

Applications

• Poultry houses, swine barns, dairy and calf-rearing facilities
• Heat-stress mitigation and improved air mixing in livestock buildings
• Wide-area ventilation where low maintenance and precise control are required

Installation and maintenance

• Mounting: suspension or wall/beam mount options depending on barn layout
• Electrical: compatible with standard farm single- and three-phase supplies; integrate with existing climate controllers via VFD
• Maintenance: direct-drive design minimizes routine service; recommend periodic visual inspection, cleaning of inlet and balance checks
