Medical Air Technology (MAT) – Helping to transform the delivery of patient care in the North West

Medical Air Technology (MAT) has recently completed its work at the new and hugely ambitious £335m Royal Liverpool University Hospital, set to change the way healthcare is delivered in Liverpool. When opened, the new hospital will be the largest medical facility in the UK and will be equipped with the latest technologies throughout, whether for sharing visitor information, entertaining and informing patients, or providing clinicians with the best environment from which to deliver world-leading treatment and patient care.

In 2019, the Clatterbridge Cancer Centre will also move to the Royal campus. The new hospital will be a major step forward in the emergence of the Liverpool Knowledge Quarter, also home to the University of Liverpool, John Moores University and the School of Tropical Medicine.

“ The new Royal will enable us to deliver state of the

art healthcare in the best surroundings in the world.

It will also help us meet the aspirations of our staff

to provide the kind of service that we would want to

see for our own families ”

Aidan Kehoe: Chief Executive at Royal Liverpool and Broadgreen University Hospitals

MAT has installed four ECO-flow™ ultraclean ventilation (UCV) operating theatres, recommended for orthopaedic surgery, in the theatre suite and three containment level 3 laboratories in the clinical services support building, including all finishes, furniture, and mechanical and electrical items.

The construction of such a building on a brownfield city centre location has proved to be a very complex process, and undertaking work on this challenging site, where project demands have evolved over several years, required a flexible and pragmatic approach from all the team at MAT. The 94,000㎡ hospital will have 23 wards and 646 single ensuite bedrooms, including 40 critical care beds and 81 emergency assessment

beds. Once completed, there will be 18 operating theatres (including robotic and hybrid theatres), making it Liverpool’s main accident and emergency centre capable of dealing with major trauma.

The main acute services include cardiology, respiratory care and general surgery together with regional and national specialist services in renal dialysis, endoscopy, ophthalmology, haematology and vascular surgery. There will also be a large clinical research facility and links to the nearby Liverpool University.

The new building will be very different from the huge 1970s concrete facility currently on the site. Its design provides a healing, non-institutional environment to enhance the patient, visitor and staff experience. The building layout maximises daylight and large landscaped gardens and tree lined pedestrian paths will help to make the hospital feel calm and less “clinical”.

“ The new Royal will enable us to deliver state of the art healthcare in the best surroundings in the world. It will also help us meet the aspirations of our staff to provide the kind of service that we would want to see for our own families ”

In 2020, Imperial College London approached Medical Air Technology (MAT) to discuss the provision of two new ISO Class 6 cleanrooms. The cleanrooms, located within the Sir Michael Uren Hub, would allow the university to further extend the range of research that could be carried out within its new White City campus.

After completing several previous cleanroom and containment laboratory projects at Imperial College London, MAT was proud and excited to once again have the opportunity to work in partnership with such a prestigious institution to deliver the new research environments.

After initial designs were developed and approved, building work began in summer 2020 and the new cleanrooms were handed over in June 2021, the entire project having taken just 11 months.

The The Sir Michael Uren Hub at Imperial College London

Imperial College London is a global top ten university with a world class reputation. Its alumni include 14 Nobel Prize winners, including Sir Alexander Fleming.

To enable the highest level of research, the university offers the best

possible facilities. One of its flagship buildings is the £90m Sir Michael

Uren Hub, located at the White City campus. Designed as a

collaborative facility, the 13-storey Hub provides space for Imperial’s

world-leading researchers, engineers, scientists and clinicians to work

alongside one another to investigate some of the twenty first century’s

most urgent biomedical and healthcare problems.


  • High standard ISO Class 6 clean areas with air change rates from 50 to 70 per hour
  • High load bearing raised and ventilated floor
  • Modular cleanroom ceiling with HEPA fan filter units
  • Complex CMR airflow and room pressure controls.
  • Complete mechanical and electrical installation including air handling units, HEPA filtration and specialist airflow and pressure controls
  • Piped specialist, hazardous and house gases, including vacuum systems
  • Hazardous gas emergency release abatement systems

What is Meant by ISO Class 6?

The new cleanrooms MAT was commissioned to design and build both had to be ISO Class 6 standard to safely accommodate the semiconductor research that would be carried out in them. Class 6, as defined in ISO 14644-1:2015 Cleanrooms and Controlled Environments, refers to the cleanliness levels that must be met within the cleanroom.

In addition to having a high air change rate, an ISO 6 environment must be accessed through airlocks to preserve pressurisation differentials and prevent the migration of particles from outside into the cleanroom space, increasing one class at a time. So, users should pass through an ISO 8 environment, then an ISO 7 environment, before entering the ISO 6 cleanroom.

MAT – Designer and Main Contractor

MAT acted as the designer and main contractor on the cleanroom project, working closely with the university to ensure minimum disruption to the other activities being carried out in the Sir Michael Uren Hub.

The team developed a design built around the complex research equipment and specialist tools that would be housed in the new cleanrooms. Work included final services connections and extensive bottled and house gases installation to several hazardous gases and associated gas detection systems.

The HVAC System

HVAC design is complex and requires a highly skilled delivery team.

MAT is an expert in the provision of specialist HVAC systems. The HVAC system is at the heart of cleanroom design. Cleanroom HVACs differ from standard systems in that they have an increased air supply, different airflow patterns, use of high efficiency particulate air (HEPA) filters, and room pressurisation, and clean to dirty room air cascades.

In order to meet the required air cleanliness, the air must pass through HEPA filters. The lower the ISO class, the more often the air must pass through the HEPA filter. This ‘air changes per hour’ rate (ACH) and the room volume are used to calculate the HVAC’s required airflow. A conventional HVAC system usually makes two to four air changes per hour, whereas in a cleanroom it can range anywhere from 10 to 250 or even more.

The ISO Class 6 cleanrooms at Imperial College London require air change rates from 50 to 70 per hour.

A Specialist Contractor

MAT designs, manufactures and installs bespoke critical ventilation systems and turnkey project solutions for new build and refurbishment projects. As a specialist contractor with many years’ experience, we are passionately committed to improving patient protection and end-user safety in demanding clinical, research and drug production arenas.

We have extensive experience of working in live environments and understand the challenges around delivering a project within an operational scenario.

In addition, MAT FM provides a range of competitively priced and highly effective service and maintenance packages for all core products and turnkey solutions offered by MAT or other suppliers, ensuring that equipment is maintained, serviced and validated correctly for optimum performance.
