The discharge electrode needle using the low dust specialty alloy, suitable for a clean environment.

　　DIC Ⅱ circuit control through new research and development, to ensure the stability of ion balance, eliminate low except electrical properties, while a large extent, to reduce the frequency of maintenance.

　　DC precipitators, ion generation, to achieve high-speed addition to electric.

　　Degradation characteristics of the standard alarm output structure, cleaning alarm, abnormal high pressure alarm ion fan, abnormal rapid reaction to external.

　　In addition to the potential of the electric field is maintained at zero volts, the ion balance can be minor adjustments.

　　* A so-called DI (Double Ion Control) circuit control means through the circuit while controlling the ion balance and the amount of ions generated, can generally achieve the best eliminating effect.
