The industrial blower consists of special multi-hole fiber paper wet curtain, water circulatory system and axial-flow blower. The wet curtain and the blower are installed on the opposite walls of the enclosed room respectively.

The operation principle of the whole unit is: when the blower operates, the negative pressure is formed inside, the outside unsaturated air is sucked to get through the surface of the wet multi-hole fiber paper curtain and cooled itself continuously due to evaporation resulted in lot of water.

The industrial blower is an ideal cooling system with its advantage in one-time investment and low operation cost (Operation cost is only 10% of air conditioning unit).
