Transforma provides a unidirectional Operation Room ceiling filtration system that ensures controlled distribution of filtered air, thanks to absolute filters positioned directly above the operating theater. The frame and filters are constructed from Stainless Steel AISI 304 or anodized aluminum, equipped with H14 filters, with all components fixed together in a perfectly planar arrangement for ease of cleaning. The diffuser is modular, allowing for easier transportation and installation, especially when the system is not delivered as a single unit.
