How it works - Introduction The system has been designed to be floor standing and mounted against an exterior wall. Air is drawn into the system via a series of circular louvres (fresh air intake, or by a concealed floor level opening positioned at the front of the system (recirculation). Both the incoming and recirculated air is controlled by insulated motorised volume control dampers. Once air has entered the system, it is drawn through a particle filter before passing through the heat exchangers and into the space.
