The Indoor HR series of mechanical ventilation units are machines that do not require ducting in the room, designed for continuous air renewal in tertiary sector spaces such as schools, offices, shops and RSAs. Available in two versions, 400 and 1000 m³/h, they are designed to be easily integrated into existing buildings. They are offered in different configurations to facilitate the connection of external air intakes (inlet and exhaust) and can be installed either on the ceiling or on the floor depending on the characteristics of the room that houses them. The Indoor HR units consist of a minimalist self-supporting structure in white pre-painted sheet metal and are equipped with rock wool thermo-acoustic insulation, which guarantees high performance also in terms of silence.
