Small wind turbine Lely Aircon 10

The Lely Aircon 10 is designed specifically to be extremely silent and a reliable source of renewable energy. With its unique design incorporating the minimum of moving parts, the Lely Aircon 10 requires only a brief and basic annual inspection and lubrication service. This in turn results in low costs of ownership during the expected lifetime of over 20 years. The Lely Aircon 10 is manufactured according to requirements of DIN EN 61400-2 certification.
