Product features

The DC-ESR-C is a bar ionizer that uses the corona discharge method to generate air ions. Air containing positive and negative ions effectively neutralizes the load on a charged object. With its low dust-emission design, this device is suitable for controlling ions in clean rooms and on clean benches. Since a small DC power supply is incorporated in the bar electrode, the device does not require a high-voltage cable. The safety design uses only low-voltage wiring, unlike other devices that require an external high-voltage power supply and high-voltage cables.

Several units can be connected together by means of connectors provided at both ends of a device (up to 3 devices, provided up to 6 devices can be connected together by changing.
Adaptor for connected specification (optional)

1. To two electrodes at the connection : The AD-02 type.
2. To six electrodes at the connection : The AD-06 type.

*1 Measured using a CPM measurement device (conforms to ESD.STM 3.1-2000) With the ion balance in a steady state, the static decay time is the time taken to decay from +1000V to +100V. Data obtained using the following parameters: Airflow: 0.3m/sec, Distance: 300mm

*2 The ozone density was measured at a distance of 150mm from the main unit's air outlet.
