An electrostatic precipitator (ESP), or electrostatic air cleaner is a particulate collection device that removes particles from a flowing has (such as air) using the force of an induced electrostatic charge. Electrostatic precipitators are highly efficient filtration devices that minimally impede the flow of gases through the device, and can easily remove fine particulate matter such as dust and smoke from the air stream.
