Description
Use:
1 generation air convection, heat dissipation. 2 to reduce air conditioning load, increase indoor air fresh. 3 out of the roof moisture, damp, steam, keep the roof is dry. 4 instead of heavy electric exhaust fan, reduce support cost saving electricity, lose noise.
Introduction:
No fan power is based on the principle of natural wind driven turbine rotation and indoor and outdoor air convection fan, air flow either parallel to the direction of the acceleration, and into the bottom vertical air flow, a device to improve the indoor ventilation effect. The fan is not electricity, no noise, long term operation. According to the laws of nature and the air flow principle, reasonable positioned on the roof top, can quickly exhaust the indoor hot and dirty gas, improve the indoor environment.
Advantage.
1 low cost, belongs to one-time investment, life-long free repair.
2 convenient installation, saving manpower resource consumption, without the need for electricity consumption.
3 material: stainless steel, quality assurance for fifteen years.
4 no power consumption, no pollution, which belongs to the environmental protection practical products.
