The Furlmatic 1803 is Marlec's largest power unit incorporating a "furling" tail system designed to orient the turbine at 90degrees to the prevailing wind in wind speeds above 35mph (15m/s). This allows the turbine to slow down, continuing to produce power whilst reducing wear on the unit. Use on land based applications where windspeeds are frequently high and sustained over long periods. Below you will see the performance specification and the dimensions of the Rutland 1803.
