Operating Room

Modern operating rooms are areas well developed to deal with air handling and infection control.

By the nature of the work conducted, infection prevention is critical and some more expensive operating areas, particularly orthopaedics, utilise lamina flow canopy’s (UCV) to maintain a near sterile atmosphere. Air Sentry is designed as modular ultra clean air system which can be a LEV, local exhaust ventilation derivative. It is designed to be fully HTM03.01 compliant and is truly modular. The specifying engineer can opt to deploy a mobile unit due to time constraints but that unit can be easily be altered to be floor, wall or ceiling supported at any point in the 25 year life cycle. All systems can handle incoming temperature and humidity controlled air or so called ‘fresh air’ and supply pressure differential.

New Operating Rooms

Air Sentry® utilises a very similar approach, albeit a higher grade filtration technology, to lamina flow. Our system allows for a considerable reduction in plant room size as the temperature and humidity controlled air can be ducted through our units. This allows for high volume positive or negative pressure control to be implemented, combined with lamina flow style recirculation. The cost of an OR designed this way can be considerably lower, whilst offering a whole room Ultra Clean™ air environment, with none of the associated entrainment issues.

Older Operating Rooms

Air Sentry® can also be used to supplement an existing operating room environment. We have clients who have installed our system into older operating room areas and these are still exceeding regulatory cleanliness tests ten years later.

Minor Procedure or smaller Operating rooms

Air Sentry® has several clients using our units for minor procedures, particularly in the private sector. Our units fully comply with regulatory requirements and have been reviewed by Care Quality Commission inspections since 2010. All of our installations report very low or zero surgical site infections.

The total cost of installing and maintaining an Air Sentry® operating area is normally lower than the older systems one years service cost.

Minor Procedures with positive pressure










Air Sentry® is aimed as a small OR Ultra Clean system which can be used to supplement older OR air handling plant to extend usable life.
