Clean Rooms



ospitals around the globe employ cascade ventilation systems to maintain positive pressurisation of operating theatres. This protects the patients and staff from the ingress of infectious agents, dust and bacteria by providing an invisible barrier of positive pressure when doors within these rooms are opened.
This is a well-established principle of hygiene and infection control is championed and used the world over.
This system can also be employed in Isolation Rooms, Aseptic Suites, Endoscopy suites, Pharmacies, Cardiac Catheter Laboratories, Sterile Services Departments, Interventional Radiology Suites, CAT 3 Laboratories and other specialist areas which may require infectious control.

Apreco have been acknowledged for their assistance in contributing to Health Technical Memorandum (HTM 03-01) which supercedes HTM 2025. Apreco have also assisted with the validation of Isolation Room design following Health Building Notes (HBN 4 : Supplement 1).
