PSEUDO-ELECTRET ELECTROSTATIC FILTER FOR LIQUIDS

摘要

The invention relates to a pseudo-electret electrostatic filter, meant for retaining suspensions from fluids, especially by dielectrophoretic activity. According to the invention, the filter comprises a coiled filament (1) comprising a flexible electric wire (2), insulated and centrally located, a thin non-insulated electric wire (3) being wound as a spiral around said wire in order to obtain a coil coiled filament, a spiral filament being helically wound around another single coil filament.
