Using steady state DC ion emission, the SCS™ Overhead
Air Ionizer 991A provides consistent static control coverage.
With its overhead mounting system, the ionizer doesn’t
compromise valuable space on the workbench, allowing
for neutralization of static charges. The steady-state DC ion
emission enables fast discharge with low airflow, providing
a more comfortable work environment for operators.
Emitter points are placed behind the fan to eliminate
field-induced charge and to ensure a homogeneous mixture
of ionized air. Also featured are open-cell foam filters on
the fan intakes, protecting the internal components from
environmental contamination.
