With industrial, commercial and light steel construction, light steel construction and ventilation were also concerned by the series of natural fan power is the use of natural convection of air, parallel to the direction of any air flow, and accelerate the transformation of a bottom-up vertical air flow to improve indoor ventilation efficiency the fruit of a plant, which do not use electricity, no hypomanic sound, long-term operation to remove indoor air, moisture and been series of non-powered fan natural succession, thereby breaking the traditional thinking, traditional wall exhaust fan installation of electricity, are not effective in improving the larger steel wide factory air environment, the traditional fan right around 2 to 3 meters scope of the results, the new roof fan power its unique design, forced by the effects of the exhaust, medium-sized businesses favor, but its high economic costs and the follow-up maintenance chores, to allow small and medium enterprises and food sigh only series non-power fan with its unique natural economical and practical, efficient energy conservation, green roof and with comparable power blower, according to the laws of nature and the flow of air flow principle, rationalization installed in the top of the roof, with speed to the indoor heat and emit foul gases, improve work environment and health protection staff, increase work efficiency.
Non-powered fan of a zero-cost operation costs, the economic costs of installation, low maintenance costs, substantial energy saving effect of ventilation,
The company developed a series of non-power roof natural ventilation system that uses high-quality Japan and the United States UBC NSK Bearings, that the whole of the natural ventilation durable and reliable operation, flexible angle structure, so that ventilation can meet for less than 32 tilt-roof installation. No power consumption, save for a large enterprise spending, good ventilation dust effect is the preferred enterprise green products.
