Abstract
An electric filter for separating impurities from air including a housing which contains separator plates disposed in spaced relationship and formed of conductive material and alternate ones of said plates are connected to opposite poles of a source of voltage.
Claims5
An electric filter for separating impurities from air comprising:
- a first housing member and a second housing member constructed of an electrical insulating material;
- at least one tubular electrostatic separator plate integrally secured at one axial end to a first side of each of said housing members, said separator plates being constructed of an electrical insulating material;
- insulating means securing said housing members together in a spaced relationship so that the first sides of the housing members face each other and so that the separator plates are coaxial and radially spaced from each other thereby forming an air passage between the separator plates;
- air inlet means formed in the first housing member and air outlet means formed in the second housing member;
- an electrically conductive coating formed on said separator plates and on the first side of each housing member;
- and
- means for connecting the electrically conductive coatings on the two housing members to opposite poles of a source of electrical energy.
