1. The fan's engineering marvel lies in its single suction design, available in a comprehensive range of machine numbers: 4, 4.5, 5, 5.6, 6.3, 7.1, 8, 9, 10, 11.2, 12.5, 14, and 16.
2. This fan exudes versatility, offering dual operational modes: clockwise and counterclockwise rotation. Observed from the transmission side, a clockwise impeller rotation signifies a right-handed fan, marked as 'right,' while counterclockwise rotation indicates a left-handed fan, labeled as 'left.'
3. Ingeniously designed, the fan's outlet position is dictated by the casing's outlet angle, customizable for both right-handed and left-handed configurations to six unique angles: 0°, 45°, 90°, 135°, 180°, and 225°. For additional machine numbers or angles, our superior manufacturing capabilities enable us to craft bespoke 'order dishes' tailored precisely to your satisfaction.
