A two-stage electrostatic filter is provided for air recirculation units. The filter includes at least one ionization stage (100) formed by parallel facing walls, in which a high-potential electrode (50) is located, and at least one precipitation stage (200) formed by parallel walls of negative potential in relation to the ionization stage. The ionization and precipitation stages-include at least one inverted U-shaped cathode (10), the opposite ends of which are mechanically and electrically integral with a transverse supporting section (20) and within which is provided at least one baffle (10b) extending parallel to outer arms (10a) of the U-shaped cathode, but with a height lower than that of the arms. The cathode (10) cooperates with a U-shaped anode (30; 1030) counterposed thereto and rendered mechanically integral by insulated supports (40). There are also provided further cathodes (110b; 2110b) for the modular expansion of the filter in the direction of its width.
A two-stage electrostatic filter for air recirculation units, comprising at least one ionization stage formed by parallel facing walls in which is located a high-potential electrode, and at least one precipitation stage formed by parallel walls of negative potential in relation to the ionization stage, wherein said ionization and precipitation stages are comprised of at least one inverted U-shaped cathode, the opposite ends of which are mechanically and electrically integral with a transverse supporting section and within which is provided at least one baffle extending parallel to outer arms of the U-shaped cathode throughout the length of the section but with a height lower than that of said arms and having means for cooperating with a U-shaped anode counterposed thereto and rendered mechanically integral by means of insulated supports, there being also provided further cathodes for the modular expansion of the filter in the direction of its width.
