Unidirectional air filtration and diffusion system for operating theatres - SQR Series
Operating theatres require very high control of environmental sterility. The choice of the air filtration and diffusion system therefore plays a decisive role in creating and maintaining the necessary aseptic level of the operating field and the surgical wound.
Thanks to its know-how in operating theatre air conditioning, Tecnair has developed a complete range of unidirectional air filtration and diffusion systems for operating theatres, capable of ensuring operating field levels of sterility in compliance with ISO 5 Class or ISO 7 Class.
SQR Series unidirectional air filtration and diffusion systems for operating theatres are the most suitable choice to minimise biocontamination while maintaining adequate working conditions for the surgical team.
