991 - 

Using steady state DC ion emission, the 3M™ Overhead Air Ionizer 991 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. Features:
