DAWANGFAN 24ft HVLS Fan for Dairy Farm Industrial Ceiling Fan

DAWANGFAN 24ft HVLS Fan for Dairy Farm Industrial Ceiling Fan

Blade shape- Streamlined variable cross-section

The blade section is from wide to narrow (304-186mm),from thick to thin (43mm-21mm).Adopts the equal chord length principle and relative linear velocity characteristics to ensure the balance pressure of the whole blade to achieve the tip,middle and roots air evenly including the middle.
