Vortex spiral duct for optimized airflow performance Innovative vortex spiral duct design minimizes airflow loss while reducing internal noise, ensuring quieter and more efficient operation. power wind system delivers rapid airflow that separates air into two distinct temperature zones, preventing unwanted mixing and helping maintain indoor temperature stability. Adjustable wind guide plate allows precise control of wind direction, making the product versatile for different installation environments and usage requirements. Key benefits Helps preserve cool air in summer and warm air in winter by effectively blocking outside air exchange, reducing energy loss. Supports a more comfortable indoor environment through controlled airflow management. Designed for compatibility with various spaces including commercial entrances, retail stores, office buildings, and industrial facilities. Practical applications Installed at the entrance of a retail store to prevent outside hot or cold air from entering, improving comfort for customers and staff. Used in office lobbies to maintain temperature control when doors are frequently opened, helping reduce HVAC energy costs. Applied in warehouse loading areas to separate internal climate from external conditions, protecting temperaturesensitive goods. Specifications and performance Spiral duct construction enhances airflow efficiency and minimizes turbulence. speed airflow capability ensures strong separation of temperature zones. Adjustable wind guide plate supports directional airflow targeting based on specific environmental needs. This product delivers a reliable and efficient solution for protecting indoor climates, reducing energy waste, and maintaining comfortable conditions across a wide range of commercial and industrial applications.
