기능

• The wide-bladed fan, which prevents air flow from dropping, achieves low noise.
• The hot air collected near the ceiling is exhausted by the roof fan to improve the working environment.
• It has an average noise reduction of 4~6dB compared to the standard model.
• The use of a wide-bladed fan overcomes the drawback of the conventional low-noise type, "noise reduction = air volume reduction," and is designed to reduce air volume reduction.
• For ventilating factories and warehouses.
• For ventilation of large stores and large spaces.
