Ventoptek Direct Driven Black Wings 50inch & 54inch Butterfly Cone Fan is a newly optimized farm ventilation equipment, professionally configured with premium Potentek brand direct-driven asynchronous motor. Adopting brand-new structural aerodynamic design, this cone fan features ultra-large air volume, full maintenance-free performance and stable continuous operation, delivering reliable long-term ventilation guarantee for modern livestock breeding farms.

Different from conventional belt-driven butterfly cone fans on the market, this model cancels belt transmission structure thoroughly. It eliminates common problems including belt aging, slipping, fracture and operational wear fundamentally, cutting spare parts replacement and regular manual maintenance costs for breeding enterprises greatly. The integrated direct-drive structure also lowers power loss during operation, boosting overall ventilation efficiency effectively.

This fan achieves outstanding performance in long-distance duct ventilation, which perfectly matches large-scale farm layout demands in South America. It is highly applicable for 100m to 140m super-long poultry houses in South American breeding zones. Without belt transmission resistance and energy loss, the fan maximizes air delivery volume, realizes uniform air circulation across the whole ultra-long chicken house, and optimizes indoor air quality, temperature and humidity environment stably.
