There was this. In addition, the conventional electrostatic dust collection filter has a structure in which the ionizer and the dust collector are separated, so safety nets must be installed on the front and rear of the ionizer as a safety device to prevent the operator's hands from touching the discharge electrodes that make up the ionizer. Therefore, the structure becomes complicated, and when cleaning or maintenance of the ionizer is required, both the safety nets installed on the front and back of the ionizer must be separated, which has the problem of poor workability.

In addition, the conventional electrostatic dust collection filter has a structure separately provided with a pair of anode and cathode terminals for applying voltage to the ionizer and another pair of anode and cathode terminals for applying voltage to the dust collector. As a result, the power connection structure through which voltage is applied to the electrostatic dust collection filter is complex, which increases costs, logistics costs, and management costs, and makes power connection work cumbersome.

In addition, it is necessary to assemble and construct the left-hand type and the right-hand type separately, taking into account the position where air is intake and exhaust depending on the situation of the place where the electrostatic dust collection filter is installed. The conventional electrostatic dust collection filter is a left-hand type. The structures of the parts applied to the over-type method are different depending on the installation direction and are therefore incompatible with each other, which causes many inconveniences in assembly and construction work in response to the environment of the location where the electrostatic dust collection filter is installed. there was.
