7.3 Meter Large Industrial Ceiling Fan For Workshop Warehouse Factory School Ventilation And Cooling Energy-Saving

Product Description

This 7.3-meter permanent magnet industrial HVLS (High Volume Low Speed) ceiling fan is a super heavy-duty large-space ventilation and cooling solution built for extra-high-bay factory workshops, large logistics hubs, mega industrial buildings and large public venues. Driven by a high-torque permanent magnet synchronous motor (PMSM) with gearless direct-drive structure, it delivers massive gentle airflow at ultra-low rotational speed, achieving uniform three-dimensional air circulation across wide areas with industry-leading energy efficiency and whisper-quiet operation.

Equipped with 5 aerodynamically optimized aviation-grade aluminum-magnesium alloy blades, it generates a continuous laminar air column that flows vertically to the ground and spreads horizontally in all directions (floor jet effect), eliminating ventilation dead zones and effectively relieving sultry heat in large open spaces. The heavy-duty all-metal hanging structure with multiple safety reinforcements ensures safe, stable and long-term operation under high ceilings. It is widely deployed for ventilation cooling, dehumidification and air quality improvement in large manufacturing plants, regional distribution centers, bulk warehouses and large-scale agricultural facilities, serving as a cost-effective, energy-efficient and reliable industrial ventilation upgrade solution.

Applicable Locations

Large-Scale Manufacturing Workshops: Suitable for heavy machinery processing, hardware manufacturing, textile mills and large assembly workshops. It promotes full-area air circulation to alleviate high-temperature sultry working environments, improves frontline worker comfort and reduces heatstroke risks. Super High-Bay Warehouses & Logistics Hubs: Ideal for elevated storage warehouses, large sorting centers and regional distribution hubs. It accelerates air exchange to reduce indoor humidity, prevents goods from damp and mildew damage, and boosts on-site operation efficiency. Heavy Industrial Plant Buildings & Aircraft Hangars: Perfect for production hangars, aircraft maintenance workshops and large-scale industrial plant facilities. The wide-coverage low-speed airflow achieves uniform temperature and humidity control across the entire plant without creating uncomfortable strong drafts. Large Public & Assembly Venues: Effective for exhibition centers, indoor stadiums, large churches and grand assembly venues. The wide-range uniform airflow solves the problem of stuffy heat in tall, spacious buildings with dense crowds. Large-Scale Agricultural Facilities: Suitable for intensive livestock breeding houses, commercial agricultural greenhouses and large-scale aquaculture facilities. It promotes uniform air flow to balance temperature and humidity, optimizes breeding and growing environments and reduces disease incidence. Large Auto 4S Centers & Repair Yards: Applicable to auto exhibition halls, large repair workshops and maintenance yards. It delivers soft and uniform air circulation to improve working comfort without disturbing operation activities.

Fan Parameters

Feature

High-Efficiency HVLS Ventilation: Adopts the High Volume Low Speed aerodynamic principle. The 7.3-meter extra-large-diameter blades push a huge mass of air to form a continuous laminar air column, achieving full-coverage three-dimensional air circulation with zero dead corners. The ventilation and cooling effect is far superior to traditional high-speed small fans. Permanent Magnet Direct-Drive Motor: Equipped with a high-efficiency permanent magnet synchronous motor with a gearless direct-drive structure, eliminating transmission loss, mechanical friction and lubrication requirements of traditional geared motors. It delivers high torque at low speed, stable operation and ultra-long service life. Intelligent Control System: Supports stepless variable speed adjustment, with optional remote control and centralized group control system. It can be linked with temperature and humidity sensors to realize automatic speed regulation, and supports remote monitoring and energy consumption management. Modular Safety Design: Modular blade connection structure with quick-lock design, convenient for transportation, installation and later maintenance. The heavy-duty steel hanging system is equipped with multiple safety protections including anti-fall, anti-sway and overload protection, ensuring safe long-term operation under high ceilings. Advanced Aerodynamic Technology: The aviation aluminum-magnesium alloy blades are precisely shaped with optimized airfoil curvature, which greatly reduces air turbulence and operation noise while improving air displacement efficiency per watt. It delivers soft and uniform natural breeze without strong draft discomfort.

Advantages

Ultra-Wide Coverage Efficiency: The 7.3-meter extra-large-span blade delivers massive low-speed airflow, covering 1000–1300 ㎡ with a single unit. The floor jet effect drives overall air circulation in the space, achieving uniform temperature and humidity distribution with no dead corners, and the ventilation efficiency is 6–8 times that of ordinary small ceiling fans. Outstanding Energy Saving Performance: Permanent magnet direct drive technology achieves ultra-high electro-mechanical conversion efficiency. Under the same ventilation effect, the power consumption is only 1/6–1/10 of that of traditional multi-fan combinations, greatly reducing industrial ventilation electricity costs with a short investment return period. Ultra-Quiet & Durable Operation: Gearless direct drive structure eliminates gear wear and mechanical noise. The aerodynamically optimized blades run smoothly with low turbulence, and the noise is as low as ≤39dB. The motor has a service life of more than 10 years, with stable performance and low failure rate for long-term continuous operation. Safe & Fast Installation: Modular split design with quick-lock blades facilitates transportation and on-site assembly. The heavy-duty steel hanging system is suitable for various concrete and steel structure ceilings, with multiple safety protection designs for reliable long-term suspension operation. Low Maintenance Requirements: Gearless permanent magnet motor requires no lubrication and no regular replacement of wearing parts. The all-metal blade structure is dust-resistant and easy to clean. Daily maintenance only requires regular appearance inspection and fastening check, with extremely low long-term operation and maintenance cost. Wide Scenario Compatibility: Suitable for installation and use in various extra-high-ceiling spaces such as large industrial workshops, logistics warehouses, stadiums, exhibition halls and large farms. It can be used independently for ventilation and cooling, or used in conjunction with air conditioning systems to evenly circulate cold air and reduce overall refrigeration energy consumption.
