- Discharge Halt Function:
Uses an external input to forcibly stop the discharge process. - Check Function:
Utilizes the CHECK indicator and output to alert the operator when it's time to clean or replace the discharge needle. - Abnormal Discharge Monitoring Function:
Uses the ERROR indicator and output to notify the operator of any discharge issues and halts the discharge process. It can be reset to cancel the stop. - Discharge Output:
The output is ON during the discharge process, allowing the operator to confirm when discharging is taking place. - Check Output:
The output is ON when the discharge needle is dirty. - Error Output:
The output is OFF when a discharge issue occurs (normally ON), and it can also be used to check the ionizer's power supply.
Details
Model : ER-VW
Features :
-
Nozzle angle adjustment mechanism
-
The angles of the two nozzles can be adjusted within a range of approximately 190° by screwing down the ends of the nozzles.
-
After adjusting the angle, turn the ends of the nozzles to tighten them and secure them at that angle.
-
-
Easy connection layout possible
-
The joint kit (optional) can be used to connect up to a maximum of 5 ER-VW units.
-
The air supply part is connected via quick connection joints, and the power supply and input / output signals can also be connected easily using connection cables with connectors at both ends.
-
Multiple ER-VW units can be connected together to provide charge removal layouts that suit the target equipment.

-
Minimum air consumption 15 ℓ/min. (ANR)
-
ER-VW can utilize air flow levels starting from a minimum of 15 ℓ/min.
-
Because the amount of air consumed is so low, the loads placed on air supply equipment can be reduced and costly clean air can be used much more economically.
-
-
No damage to electronic devices from inverse charging
- A high-frequency 68,000 Hz AC corona discharge is used, so that (+) ions and (-) ions are emitted in rapid alternation.
- Because there are none of the sudden ion discharges that occur with other types, there is no tendency to partial oppositely-charging even when charge removal insulators with different localized charges, so that any damage to electronic devices can be avoided.

-
Produces excellent ion balance
-
The adoption of high-frequency AC method allows extremely stable ion balance to be achieved.
-
The ion balance is not affected by the pressure of air supplied and the setup distance, so no troublesome adjustments are required after setup.

-
Compact and thin design
- The thickness of the unit is 18.9 mm 0.744 in.
- Even so, the nozzle angles can be adjusted, so that they can still be installed in places where there are space restrictions, such as inside other equipment or along several adjacent production lines.
(Notes:1) Minimum width dimensions after nozzle angle adjustment2) Maximum width dimensions after nozzle angle adjustment
-
Air supply monitoring function
- This function causes discharging to stop automatically if the supply of air drops below a certain pressure.
