1. Meticulously crafted, the fan exhibits a single suction design, available in machine numbers 4, 4.5, 5, 5.6, 6.3, 7.1, 8, 9, 10, 11.2, 12.5, 14, and 16.
2. Versatile by design, this fan supports dual operational modes: clockwise and counterclockwise rotation. From the transmission side view, clockwise impeller rotation signifies a right-handed fan, labeled as 'right,' while counterclockwise rotation indicates a left-handed fan, labeled as 'left.'
3. Masterfully conceived, the fan's outlet orientation is determined by the casing's outlet angle. Both right-handed and left-handed models allow for customization at six precise angles: 0°, 45°, 90°, 135°, 180°, and 225°. Should your specifications call for alternative machine numbers or angles, our manufacturing prowess enables us to produce custom 'order dishes' tailored to your exact requirements, ensuring unmatched satisfaction.
