Square Negative Pressure Fan Introduction and Working Principle by Xianrun Blower

Square negative pressure fan is a new kind of axial flow fan. Shell material of square negative pressure fan generally are galvanized plate or stainless steel, the purpose is to enhance the corrosion resistance and strength of square negative pressure fan.

Because the fan shell shape is square, so called square negative pressure fan,this types fan has the features of nice appearance, large air volume, low energy consumption, low speed, low noise, dust proof, rain proof, etc.

Working Principle of Square Negative Pressure Fan

Working principle is to use negative pressure ventilation, and reach the purpose of air circulation and ventilation cooling. 

When the square negative pressure fan starts to work, it exhaust dirty air, hot air, muggy air from indoor to outside by large blades rotation, at the same time, there will be differential pressure between the indoor and outdoor air, then the indoor air become thin, forming a negative pressure zone, finally, the outdoor fresh air will flow into the indoor naturally due to the pressure difference compensation.
