SPI Counter Workstation Ionizer

Operation, Installation and Maintenance

Figure 1. SPI Counter Workstation Ionizer

Description

The SPI Counter Workstation Ionizer is designed to 

effectively eliminate localized static charges which exist 

in the work area.

Item

Description

94000

Counter Workstation Ionizer, 120VAC

94001

Counter Workstation Ionizer, 220VAC

94003

Replacement Emitters, Pack of 2

NOTE: If your ionizer was manufactured prior to 2009, 

use item 

94002

 as your replacement emitter pins.  

Contact customer service should you need assistance 

with determining your ionizer’s year of manufacture.

Operation

The Counter Workstation Ionizer comes completely 

balanced and ready to use.
1.  Place the ionizer on a flat, level surface.

2.  Plug the ionizer into an appropriate electrical outlet.

3.  Power the ionizer using the power switch located 

at the back.

FOR BEST RESULTS

1.  Keep the targeted area clear and free from 

obstructions of ion flow.

2.  Effective ionization range: 12" (305 mm)

3.  Position the ionizer so its emitter points are 

directed towards the area to be ionized.

REMEMBER

1.  Keep the work area clear of all static generative 

materials.

2.  Use only approved static control grounding 

methods and material handling equipment.

3.  By properly using ionized air, all static potentials 

in the work area are greatly reduced, even when 

humidity levels decrease.

CAUTION: 

Care should be exercised during handling 

to prevent the unit from falling face down.  The delicate 

emitter pins will be damaged or broken if this happens.

Maintenance

The Counter Workstation Ionizer is designed to be 

virtually maintenance free.  The emitter points can be 

cleaned when there is a visible accumulation of dirt.  

Generally this would be twice a year, depending on the 

cleanliness level of  the working environment.
1.  Check the emitter points for dirt accumulation.

2.  Be sure the unit is unplugged.

3.  Wipe emitter point with a swab dampened in 

isopropyl alcohol.

4.  The outside case may be wiped down with a soft 

damp cloth.

Calibration

The Counter Workstation Ionizer is factory set to 

achieve a maximum balanced ion output in standard, 

non-air assisted applications.  To certify calibration, 

we recommend ANSI/ESD association standard ANSI/

ESD STM3.1.
Objective: To observe, test and record performance 

levels of ionization units, utilizing readily available 

equipment, thereby verifying or certifying calibration.

EQUIPMENT USED

EMIT 

50571

 Charged Plate Analyzer

PROCEDURE

1.  Position the Counter Workstation Ionizer 12 inches 

(305 mm) away from the face of the Charged Plate 

Analyzer.
