The evolution of ultraclean ventilation

Airflow modelling of MAT UCV canopy undertaken by University of Manchester

The design of ultraclean ventilation (UCV) systems has evolved. We’ve kept the best part – the graded airflow diffuser – but how have a canopy for all scenarios.


In the UK, ultraclean ventilation (UCV) is required for all orthopaedic surgery, as detailed in HTM 03-01 (2021) guidelines. Ultraclean ventilation is an essential step in maintaining a high quality of the air in the operating theatre and therefore controlling the risk of surgical infections. 


MAT is known throughout the UK for the ECO-flow UCV system, which eliminates dangerous airborne particles within the operating theatre clean zone for safer surgery. As well as being very quiet, it offers reduced energy usage compared with other similar units on the market, supporting government and hospital ‘net zero’ energy efficiency targets. This is achieved without any reduction in the level of performance.

ECO-flow canopy options:


Each model of UCV canopy is available at standard size 2.8m x 2.8m clean zone or with larger size 3.2m x 3.2m clean zone.


Canopies are supplied on their own, or as part of an equipment package, or in a total turnkey operating theatre solution. We offer vendor neutrality, with the option of fitting free issue equipment. We can also provide all the ancillary products required to complete your turnkey installation.
