Advantages
1. Automatically operate. Take advantage of energy from nature, exhausting turbid, humid hot air to exterior and supplying fresh air to interior. Produce air convection as a heat radiator, reducing indoor temperature, increasing air fresh. Reduce air conditioning load, increasing the cooling effect.
2. No operating cost, no electricity consumption, environmental protection, energy-saving
3. No maintainance needed, life-long service
4. Light weight, strong and durable construction
5. Weather resistance, strong fray resistance, fine non-viscidity, self-cleanness, high revolving sensitivity and high air venting efficiency.
6. Easy installation. Installation Position: Flat roof, pitched roof, concrete roof and contour plate of various industrial plants.
