The twin nozzle design ensures that less extraneous air enters the air curtain, while the outflow is wider. Resistance to the influence of external airflow has been strengthened, greatly improving insulation against heat and cold.
By adjusting the installation angle of the main unit, the airflow angle can be altered both internally and externally.
The rectification plate creates a highly directed, discshaped flow by transferring airflow from the propeller fans without reduction to volume or velocity. The plate forms the air into a smooth hemispherial wall, producing a high speed current in a single direction.
New innovations in high-tech hydromechanics have made Mitsubishi Electric Extrafan run so quiet and improve the efficiency.
