Extended High Negative Pressure Cone Fan

Key Features & Selling Points

• Extended Cone Design for High Static Pressure: Features an elongated cone housing specifically engineered to handle high static pressure conditions, maximizing airflow acceleration and discharge efficiency in tunnel-ventilated houses.

• Ultra-High Airflow Capacity: Delivers massive air exchange volume to quickly exhaust heat, humidity, dust, and harmful gases (such as ammonia and hydrogen sulfide), maintaining an optimal breeding environment.

• Exceptional Energy Efficiency: High-efficiency motor paired with optimized aerodynamic blades ensures peak ventilation performance with minimal power consumption.

• Heavy-Duty & Corrosion-Resistant Build: Constructed from high-strength galvanized steel or fiberglass, engineered to resist severe corrosion in humid and harsh agricultural environments.

• Tight Sealing & Draft Protection: Equipped with automatic precision shutters/louvers that seal tightly when inactive to prevent cold air drafts, rain, and insects from entering.

Applications

• Livestock & Poultry Housing: Poultry houses (chickens, ducks), swine barns, and dairy cattle housing utilizing tunnel ventilation systems.

• Agricultural Greenhouses: Commercial greenhouses requiring continuous high-volume air exchange and temperature control.

• Industrial Facilities: High-humidity workshops, chemical storage facilities, and factories needing high-performance negative pressure exhaust.
