Ceiling fan efficiency can be cost-effectively improved by at least 50 % by using the Environment Friendly technology - BLDC. If these efficiency improvements are implemented in all ceiling fans - 70 TWh / year can be saved and 25 million metric tons of carbon dioxide equivalent (CO 2) emissions per year can be avoided globally.Gluon GPL 2020 Ceiling Fans are European health, safety, and environmental protection standards compliant products.
