Basic Information
Accommodate a range of applications thanks to outstanding ion balance, robust dust resistance, and an extensive nozzle selection
UL, CSA : Certified by TÜV SÜD America Inc. (ER-VS02 only)
![Optimized discharge needle tip shape for even more stable ion-producing power [ER-VS02]](https://ap.industry.panasonic.com/hs-fs/hubfs/pid-corp/products/fasys/staticsys/staticsys/er-v/images/pic11.jpg?width=350&height=160&name=pic11.jpg)
The discharge needle tip’s spherical shape enables more stable ion production while making it less likely that the shape of the tip will change over time as a result of electrical discharge.
Improved maintenance cycle [ER-VS02]
(* When used in an operating environment that complies with Panasonic Industry requirements)
Selection of nozzles for different applications
In addition to eight standard nozzle types, including shower and tube nozzles, We offers a range of differently shaped nozzles (including made-to-order models).
Produces excellent ion balance
The adoption of high-frequency AC method allows extremely stable ion balance to be achieved. Because the ion balance is not affected by the pressure of air supplied or by the setup distance, no troublesome adjustments are required after setup.
Ultra-compact design accurately removes charges of objects even from narrow spaces
The main unit is merely 109 x 27 x 28 mm 4.291 x 1.063 x1.102 in, so it can easily be combined with other devices and also be installed as an add-on. Furthermore, the highvoltage power supply is built-in, so no extra space is required except for the ionizer itself.
The discharge needle can be removed from the rear of the main unit, so there is no need to remove the nozzle when replacing the needle. Maintenance is easy even when the ion air outlet is located close to the object.
A signal from an external device can be used to turn discharge ON and OFF.
Sensors can be used to detect the objects so that the ion air is generated only when required.
The discharge ON / OFF status can be checked using an LED display. This lets you avoid problems such as when the power is on but no discharge is occurring.

・Definition of Discharge: The state in which the voltage changes from 1000V to 100V, or from -1000V to -100V.

------------------------------ Tab9 showing ------------------------------
- After wiring, reconfirm the wiring connections before switching on the power supply.
- Note, wrong wiring will damage the product.
- Verify that the supply voltage variation is within the rating.
- Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction.
Others
・Only connect an isolated DC power supply, for example one equipped with an isolating transformer, or the optional AC adapter ER-VAPS1 to the product.
・If an auto-transformer, etc. (single winding transformer) is used, this product or the power supply may be damaged due to short-circuit.
- Do not use this product beyond its rated specifications. Doing so can cause product breakdown, non-function, or damage. Furthermore, it will also cause a marked reduction in product life.
- Never disassemble, repair, modify, or misuse this product, as this can cause an accident or malfunction.
- Do not throw this product into fire: it may explode or generate poisonous gas.
- Since high voltage is applied to the discharge needle, keep your fingers, body, metal, e.g. wires or tools, etc., away from the needle. If you fail to keep away from the needle, electric shock or malfunction may be the result.
- This product is not explosion-proof. Do not use it in places where combustible or flammable material is present. There is a danger of catching fire.
- Since this product emits ozone into the atmosphere, circulate air to prevent foul smells. If ozone lingers for long periods, metals, etc. may oxidize / decay. Furthermore, do not try to confirm that foul smells are caused by the ozone by drawing your face near the nozzle outlet and air outlet: you may hurt your nose, throat, etc.
- Do not use this product in steamy or dusty places, in places where water and oil splash, or where spatter flies when welding.
- If the power supply is switched on immediately after being switched off, fault output may be generated. After the power supply is switched off, wait at least 1 sec. before switching it on again.
- Confirm the wiring and piping state before supplying power or air. Wrong wiring and piping may cause malfunction.
- Do not use this product for any purpose other than charge removal.
- When this product is no longer usable or required, dispose of properly as industrial waste.
- If the air supplied to this product is turned ON / OFF by a solenoid valve, for example, make sure to turn the discharge halt input ON / OFF simultaneously.
- Use air (dry, clean air) for the fluid. Any fluid other than air (dry, clean air) or even air containing corrosive gas may cause an accident or malfunction.
- Do not use air that contains foreign particles, e.g. carbon dust, dust, water or oil. Since these substances may cause electric shock or malfunction, take appropriate countermeasures, e.g. install an airfilter, air-drier, etc.

Piping
<Mounting example of ER-AF20 + ER-VS02>
- Fit the pneumatic fittings on the both sides of this product to connect to the pneumatic tube, as the figure shown above.
Notes:
1)Since this product is made by aluminum alloy, make sure that excessive force is not applied.
2) This product is for removal of solid particles. Remove water, oil, etc., in the primary pressure side.
Cautions
- Before the piping, make sure to sufficiently carry out internal flashing (blowing of compressed air) of the pipe. If scrap or sealing tape, generated during work, or rust, etc., gets inserted, it will cause clogging.
- Use air (dry,clean air) which does not contain water, oil, etc. Water or oil will cause clogging or reduction in performance.
- Do not use with a fluid or in an environment containing the following substances:
• Organic solvents · Ester phosphate type hydraulic fluid
• Sulfuric acid gas · Chlorine gas · Acids - This product is for industrial use. Do not use it in equipment affecting human life.
- Never disassemble or modify this product.
- When disposing this product, dispose it as industrial waste.
Pressure drop
- When the mini line filter (ER-AF10/AF20) is fitted, a pressure drop occurs. Adjust the primary air pressure so that the secondary air pressure is within the air pressure range of the ionizer. (Take are that the air pressure range differs depending on the nozzle. Furthermore, in case the filter is used with the max. processed air volume, approximately 0.1 MPa of pressure drop occurs.)
- Take care that if the air more than the specified processed air volume is applied, the efficiency will deteriorate.
