Shelter AHU

Duct type shelter ventilation devices are used to deliver fresh air in shelters. These devices can be used at two different positions. In daily use, the air passes through the bypass cell and optional G4 filter to be given to the environment. When necessary, for example during wartime, the air could be passed through the G4 filter, activated carbon filter and HEPA filter to remove nuclear and harmful gas spills with the aid of the bypass unit.
