Small and light 600W variable speed blower is designed for air suction and blow with large and steady air volume which can be adjustable by built-in potentiometer, 1.5V-10V, 1.5V-5V, or 4-20mA speed control. It is widely applied for ventilation, dust extraction or cooling of medical equipment, environmentally friendly cleaning, lithium battery equipment, printing and other industrial application fields.

Air Vacuum/ Volume Curve Graph

Tips: Pressure-Flow Characteristic Curve of the Air Blower

Theoretically speaking, the pressure-flow characteristic curve of the air blower is a straight line. However, due to the loss of friction and resistance inside the blower, the actual pressure and flow characteristic curve decline gently with the increase of flow rate, and the corresponding power-flow curve of the blower increases with the increase of flow rate.

When the blower runs at a constant speed, the working point of the blower will move along the pressure-flow characteristic curve. The operating point of the blower depends not only on its own performance, but also on the characteristics of the whole system. When the resistance of the pipe network increases, the pipe performance curve will become steeper. The basic principle of blower regulation is to obtain the desired operating conditions by changing the performance curve of the blower itself or the characteristic curve of the external pipe network.
