1. With meticulous attention to detail, the fan is designed with a single suction mechanism and is available in precise 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 boasts versatility, offering dual operational modes: clockwise and counterclockwise rotation. Observed from the transmission side, a clockwise impeller rotation indicates a right-handed fan, represented by 'right,' whereas a counterclockwise motion signifies a left-handed fan, indicated by 'left.'
3. Ingenious design allows the fan's outlet position to be expressed through the casing's outlet angle. Both right-handed and left-handed models can be customized to six distinct angles: 0°, 45°, 90°, 135°, 180°, and 225°. Should alternative machine numbers or angles be desired, our manufacturing expertise enables the creation of bespoke 'order dishes' to meet your precise satisfaction.
