The Trek Model 930 Benchtop AC Air Ionizer is effective in solving

problems in the workshop or on the production floor by
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
cleaning 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.
