Delivered via a screened or screenless canopy over the operating theatre clean zone, a UCV system provides a method of diluting air to the level required in HTM 03-01 (2021). 

The design philosophy of a conventionally ventilated operating theatre is based on the need to dilute contaminants and control both the condition and movement of air in an operating suite. UCV is a means of significantly increasing the dilution effect by providing a large volume of clean filtered air to the clean zone in which an operation is performed and sterile items are exposed. 

Air is discharged above the operating zone, its downward displacement purging the clean zone of any contaminants and particles generated within it. The airflow in and around the clean zone also prevents particles from outside the zone from entering (entrainment).

MAT's ECO-flow range is an energy-efficient and highly effective way to provide a safe environment and is recommended for use in orthopaedic surgery.
