0G® [zerø gravity] is the lift and slide option which adopts the principle of passive magnetic levitation for the movement of doors. The frame, lifted up by powerful Ironlev® magnets slides, floating over a small track, without noise, without friction and without the need for electricity. With its technology, 0G® allows you to manually open and close large sliding doors with weights of up to 1000 Kg. The system consists of a floor mounted levitation unit that contains the sliding rail, the magnetic skids and the beam connecting to the door and is accessible for maintenance through movable roof profiles that can have, in their visible surface, the same finishes as the floors, for perfect continuity between the interior and exterior of the building. Only an 8.5 mm gap, closed by brushes, remains visible in the floor as the door slides open, without any protrusion and, therefore, no chance of tripping. In the upper part of the ØG sash, mechanisms are provided in order to counteract the lifting thrust of the magnets and lower the panel, ensuring tightness and closure. The system does not require electricity, it works manually even with significant weights, over 1000 kg.
