Desco 50663, Zero Volt Benchtop Ionizer, 120VAC
Desco 50663, Zero Volt Benchtop Ionizer, 120VAC
The Desco 50663 Zero Volt Benchtop Ionizer is a single-fan, steady-state DC ionizer listed in a 120VAC configuration for electronics workstations. It is intended to help neutralize electrostatic charge on insulators and ungrounded conductors within its working area. Three fan speeds allow adjustment for the process, while a stainless steel enclosure supports bench installation.
Use ionization alongside your facility's required grounding and personnel controls, not instead of them. Position the unit for the actual workpiece and verify performance at the point of use.
Best Uses / Applications
- Electronics assembly benches with necessary process insulators.
- Repair and rework stations needing supplemental charge neutralization.
- Inspection and component-handling areas where ionization is specified by the ESD program.
- Workstations needing adjustable airflow, subject to application testing.
- Static-control programs with documented ionizer maintenance and verification.

Key Features
- Benchtop charge-neutralization support for suitable process materials.
- Three fan speeds for airflow adjustment.
- Stainless steel housing.
- Sealed-plenum construction; this does not establish particle-free airflow or a cleanroom certification.
- Feedback alarms supporting the manufacturer's operating procedure.
- North American power cord listed as included.
Selection and Installation Checks
This listing is the 120VAC configuration. The previous catalog copy describes internal input-voltage selection; do not assume the unit is automatically universal-voltage or modify internal settings without current manufacturer instructions and appropriately qualified service.
- Confirm the unit's nameplate and supply compatibility before connection.
- Position the ionizer using the manufacturer's installation guidance, accounting for distance and obstructions.
- Select airflow appropriate for the workpiece and process.
- Verify offset voltage and discharge performance at the intended work location using your approved procedure.
- Maintain emitters and other serviceable parts according to current manufacturer instructions.
The listed performance values do not guarantee identical results at every distance, fan setting or bench layout. Ionizer performance does not establish compliance of the entire ESD-controlled area.
Ionization vs. Grounding
| Control | Role | Important Limit |
|---|---|---|
| Benchtop ionization | Help neutralize charge on suitable insulators and ungrounded conductors | Performance depends on placement, operating conditions and maintenance |
| Approved grounding | Provide the required charge-dissipation arrangement for groundable items and personnel systems | Connections and system performance require verification |
| Combined ESD program | Apply the controls needed for the process | No single product certifies the complete workstation |
Accessory References
The existing listing identifies 60507 replacement emitter pins, 60466 mounting arm and 60509 motion sensor as compatible accessories. Confirm current compatibility and supply separately before ordering; this listing does not establish that those accessories are included.
Frequently Asked Questions
What is the Desco 50663 used for?
It is a benchtop ionizer intended to help neutralize electrostatic charge on insulators and ungrounded conductors within a suitable work area.
Does it replace wrist straps or mat grounding?
No. Use it alongside the grounding and personnel controls required by your documented ESD program.
What is the listed input voltage?
This listing is for 120VAC. Confirm the actual unit's nameplate and current instructions; do not assume automatic universal-voltage operation.
What coverage and performance are listed?
The catalog lists a 16 in × 24 in coverage area and less than 2-second discharge time with ±3V offset at 12 inches. Verify test conditions and installed performance rather than treating these values as universal results.
Can I adjust the fan speed?
The listing identifies low, medium and high settings, with 50–100 CFM airflow. Select and verify a setting suitable for the actual process.
Does stainless steel construction make it cleanroom-certified?
No specific cleanroom certification is established here. Evaluate materials, airflow and contamination requirements for your facility before selection.
How often should it be cleaned and tested?
Follow current manufacturer maintenance instructions and your documented ionizer-verification plan. No universal maintenance interval is established by this listing.
What should we do if it alarms?
Follow the manufacturer's alarm response and your facility's corrective-action procedure. Do not assume a running fan or lit indicator establishes effective ionization.
Are replacement pins and mounting accessories included?
The catalog identifies compatible accessory references, but does not establish inclusion. Confirm package contents and required accessories before purchase.
