The AC Unit is a small unit designed to operate in collaboration with the indoor air conditioning unit. The AC Unit is the perfect solution for rooms such as classrooms and kindergartens, and for every closed area measuring between 50 m2 – 150 m2. The system ensures reliable and consistent conditions that help reduce the spread of pathogens. The basic principal is the permanent flushing of the area with clean air reinforced with positive and negative ions. Its rigid housing renders the AC Unit strong and durable ensuring a long life span and protection for the Sterionizer unit. The AC Unit uses the air flow from the indoor air conditioning outlet.
