Axial fans directly affect the cooling efficiency of towers with their rotation speed, fan type and the air flow rate they create. They draw air from the atmosphere through the louvers, pass it through the fillings and release it back into the atmosphere through the fan chimney. Fan blades vary in terms of the material they are made of. They are manufactured from glass fiber reinforced polypropylene, glass fiber reinforced polyester and aluminum extruded profile, polypropylene materials.

Water cooling tower with axial fan, small size fans are made of CT PP or PP. The connection plate is made of aluminum alloy. For large size fans, CTP or aluminum extruded profile material is used.
