Abstract
An improved electrostatic fluid filter is disclosed which is particularly useful in high performance clean rooms for the semiconductor industry. The electrostatic fluid filter is tubular in design and has an inlet port for supplying fluid (e.g., liquid, air) to be filtered and an output port from which relatively pure fluid flows. The filter includes a high voltage conductor which is disposed along the axis of the tube and which is surrounded by a ridged polytetrafluoroethylene insulator. Fluid is directed along the length of the filter parallel to the conductor. Contaminating particles in the fluid are transformed into electrical dipoles and are attached to the high voltage conductor.
