Data sheet for UV222 Downlight

Designed to be fully integrated in suspended ceilings

Disinfection, easily integrated

Children and young adults are among the most vulnerable, being particularly affected by the pandemic, during which over 90% of schools worldwide were fully or partially closed. Many organisations have pointed out the high risk of intergenerational inequality, and the need to find new solution to prevent this in the future.

Far UV-C has been identified as the best emerging technology to fight the spread of pathogens in occupied spaces. UV222 Downlight can add substantial protection against aerosolised pathogens in hightraffic classrooms, offices and hallways.
