Trek Model 930 BenchTop Ionizer

The Trek Model 930 Benchtop AC Air Ionizer is effective in solving neutralizing static charges that can cause ESD (electrostatic discharge) damage to sensitive semiconductor and LED devices due to contamination, dust attraction and device handling problems. The powerful high performance of the 930 provides efficient high volume air ionization and together with an exclusive automatic ion balance feature which generates the appropriate positive and negative ions reduces electrostatic charge generated voltages at the work surface to less than ±5 V.

The compact size and the strength of the built-in fan in the Model 930 enable it to perform in a wide variety of settings and adjust to a wide range of air volume input levels. The fast discharging time eliminates electrostatic charges from devices and surfaces in one second or less for distances up to 30cm from the center of the air source. This is compliant with International Standards (IEC 61340) which covers the requirements for the design, implementation and maintenance of an ESD control program.

The 930 utilizes a Titanium electrode, a stainless steel housing, and is equipped with a built-in cleaning brush. The operator can perform periodic cleaning to help maintain the unit's high ionization efficiency by simply turning the center knob on the ncleaning brush to sweep the ionizing elements clear of dust and other contamination. LED lights on the front panel indicate to the operator the status of the ion balance, as well as power on status, fan operation and abnormal voltage or ion levels. The unit is equipped with a washable reusable polyurethane air filter.


Show/Hide Product Technical Information


Automatic, High Speed Static Charge Elimination
Generates an equivalent amount of plus or minus ions to completely meliminate electrostatic in less than 1 second at a distance of 30cm or less from the center of the air source.

Built-In Self Correction
