Abstract
A filter made of nonwoven fabric, paper or the like for gaseous media, having an electrically conductive coating made of a conductive substance of pulverizable materials, in particular from electrically conductive carbon-black particles and/or powdery metal particles or other pulverized materials, the carbon-black particles or metal particles being fixed to the filter fibers with the aid of binding agents, and the conductive coating being applied in a reticulated manner on the filtering layer.
Claims22
A filter for gaseous media comprising a filtering fiber layer of nonwoven fabric or paper having an electrically conductive coating made of a particulate conductive material selected from the group consisting of electrically conductive carbon-black particles, powdery metal particles and pulverized conductive materials and mixtures thereof, the particulate conductive material being fixed to the filter fibers by a binding agent, and the conductive coating being applied in a reticulated manner on the layer, said coating thereby having a reticulated formation with openings to retain both permeability and an antistatic finish.
