1. The fan is meticulously crafted with a single suction system, featuring machine numbers such as 4, 4.5, 5, 5.6, 6.3, 7.1, 8, 9, 10, 11.2, 12.5, 14, and 16.
2. This fan is remarkably versatile, offering two operational orientations: clockwise and counterclockwise rotations. Viewed from the transmission side, a clockwise impeller rotation designates a right-handed fan, denoted as 'right,' while a counterclockwise motion signifies a left-handed fan, indicated as 'left.'
3. Ingeniously designed, the fan's outlet position is characterized by the casing's outlet angle. Both right-handed and left-handed configurations are customizable to six distinct angles: 0°, 45°, 90°, 135°, 180°, and 225°. Should other machine numbers or angles be required, our expert manufacturing capabilities empower us to craft bespoke 'order dishes' tailored to your utmost satisfaction.
