The ACi 4400 series utilises motors with GreenTech EC technology offering enhanced performance with a fraction of the energy usage of conventional motors. High pressure and airflow can also be achieved with a low operating noise. A wide selection of speeds are available with varying nominal voltages. These units are equipped with maintenance free ball bearings and have a service life of more than 62,500 hours, reducing maintenance costs.

GreenTech EC refers to the motor used in multiple series’ of fans from the ebm-papst range. These motors have been specifically developed to offer maximum energy-efficiency and enable the equipment to be as economically as possible. This gives a reduction in operating costs while still giving improved performance over conventional motors. They also set a new standard in reliability and service life further reducing any operating and maintenance costs.
