Patent ID: 7081155

Claim:
Particle separator having a flow passage for the air to be cleaned, said particle separator being intended for cleaning air from electrically charged particles and comprises at least two electrode element surfaces ( 1 , 2 ; 101 , 102 ; 201 , 202 ; 301 , 302 ) arranged substantially parallel to each other and at a mutual gap width (d), at least one electrode element surface ( 2 ; 102 ; 202 ; 302 ) comprising a very high ohmic material, optionally with a resistivity corresponding to or higher than antistatic, and that the particle separator also is intended to be connected to a high voltage source (HVU), said second electrode element surface ( 1 ; 101 ; 201 ; 301 ) being intended to be connected to the pole of the high voltage source (HVU) having the lowest absolute potential, wherein, the electrode element surface ( 2 ; 102 ; 202 ; 302 ) made from high ohmic material is equipped with at least one current carrying or semi-conductive means (b, b′) arranged at a distance from the edge portions (k 1 , k 1 ′, k 2 , k 2 ′) of the electrode element surface ( 2 , 102 ; 202 ; 302 ), and the current carrying or semi-conductive means (b, b′) is intended to have a galvanic connection to the pole of the high voltage source (HVU) having the highest absolute potential.
