EAN 581 Electrostatic Aerosol Neutralizer
Corona-discharge charge conditioner generating positive and negative ions for controlled aerosol neutralisation or unipolar charging, without a radioactive source.
Model Overview
| Model | Group | Positioning | Core fit |
|---|---|---|---|
| EAN 581 | Corona-discharge aerosol neutralizer | Bipolar neutralisation and controlled unipolar charging without radioactive sources | Filter testing, aerosol research, separator evaluation and quality assurance |
Key Features
Positive and negative ion generation
Two ionisation heads allow production and controlled mixing of positive and negative ions.
Neutralisation or targeted charging
The EAN 581 can establish a controlled bipolar charge distribution or provide unipolar-positive or unipolar-negative charging.
Non-radioactive operation
The corona-discharge principle does not use an ionising-radiation source and therefore does not require occupational radiation-protection handling.
Integrated spark detection
Built-in monitoring supports safe operation of the high-voltage ionisation system.
High-flow aerosol conditioning
The mixing chamber supports aerosol flows up to 250 L/min, with particle-free dry compressed air supplied to the ionisation heads.
Test-system integration
The separate control unit and compact mixing chamber can be incorporated into filter, separator and aerosol research systems.
