Enhanced inverter performance and system performance are achieved by the addition of a ?Direct Current? drive, resulting in up to 10% more efficient than standard 'AC' (Alernating Current) Systems.

The variable speed compressor(inverter) enables the system to rapidly reach the desired roomtemperature setting. Once the desired room temperature has been achieved the compressor rotationspeed is reduced, saving up to 30% in energy usage (when compared to standard fixed speed systems)

A bigger flap delivers air quickly to every corner of the room and the powerful, sweeping air flow eliminates dead zones and improves the cooling and heating effect.

The trapezoidal blades cut the air diagonally to minimise air resistance and the conical blade fan ensures a high airflow. With this diagonal air blow, less friction is caused, which reduces noise and improves efficiency. The fan diameter has been increased from the conventional 90mm to 100mm.
