In the midst of the Industry 4.0 wave sweeping the globe, ventilation and heat dissipation systems are facing unprecedented challenges. According to market research data from QYResearch, as global industrialization, urbanization, and the booming construction sector accelerate, the demand for ventilation, cooling, and air handling equipment continues to rise, driving the continuous expansion of the related fan market.
However, traditional fans fall short when faced with the challenges of limited space, noise control, and energy optimization. With its revolutionary design, the LONGWELL cross-flow fan is bringing a game-changing breakthrough to the industrial ventilation field with its unique “compact size, immense power” advantage.
Cross-Flow Fans: Redefining Industrial Ventilation Standards
A cross-flow fan is a special type of fan where airflow travels tangentially to the cylindrical impeller. Its structure features a distinctive long, rectangular design. Unlike traditional fans, it draws air in from one side of the housing and discharges it perpendicularly along the length of the fan, creating a broad and laminar airflow pattern.
This design offers three core advantages:
- Ultimate Space Adaptability: Its flat structure is perfectly suited for narrow equipment interiors or hidden installation scenarios.
- Ultra-Low Noise Operation: The optimized airflow path significantly reduces fan noise, creating a quiet working environment.
- Uniform Airflow Distribution: The elongated outlet provides linear coverage, avoiding the localized turbulence common in traditional fans.
LONGWELL's Technological Innovation: The Secret to Its "Compact Power"
Precision Aerodynamic Design
LONGWELL cross-flow fans feature a patented impeller structure, optimizing the blade pitch angle and guide vane angle to achieve maximum airflow output within a limited volume. Measured data shows that at the same power, its airflow is 30% greater than traditional centrifugal fans, while its volume is reduced by 40%.
Intelligent Energy Management System
Equipped with brushless DC motor technology and PWM speed control, it achieves:
- Energy Efficiency Ratio (EER) of 5.0 or higher, leading the industry
- Smart temperature control for automatic speed adjustment, reducing energy consumption by 25%
- 110V-220V wide voltage adaptability for global use
Industrial-Grade Durability
