In the pursuit of reducing air borne bacteria in operating theatres, the Focus 1000 Clean Air Operating Theatre Ventilation System by Camfil Airepure provides a controlled distribution of biologically clean air at the operating table, while reducing the risk of contamination from outside the clean zone. Designed to be constructed in a modular form, the Focus 1000 unit enables installation into existing operating theatre facilites.
The Focus 1000 configuration provides superior air quality at the operating theatre table level compared to the conventional arrangement of individual terminal mounted HEPA filters in the theatre ceiling.
Camfil Airepure operating theatre ventilation systems are designed to comply with the Australian Council on Health Care Standards (ACHS) guidelines for the air flow and velocity and at the operating table level and the performance requirements of the Health Technical Memorandum (HTM) 03 with respect to supply air velocity below the diffuser. These systems are of a proven design where the air distribution profile has been demonstrated by computational fluid dynamic (CFD) modelling and validated by a full size installation.
The following design characteristics are standard of the Focus 1000 Clean Air Operating Theatre Ventilation System:
The following design characteristics are optional for the Focus 1000 Clean Air Operating Theatre Ventilation System:
The following minimum standards apply to the Focus 1000 Clean Air Operating Theatre Ventilation System:
The CFD modelling diagram shows the uniform controlled air movement acheived through the Focus 1000 Clean Air Operating Theatre Ventilation System. The various shading of air flow depicted in this CFD modelling shows the face velocity at the ceiling diffuser and demonstates the table height as being within the range of the DHS guidelines for the operating theatre ventilation systems. The air distribution moves downward and outwards from the table, providing a clean air zone by moving the air in a controlled and uniform fashion. Any particulates forming in the clean zone under the Focus 1000 by the theatre team or a procedure within the theatre are quickly diluted through the controlled air distribution and expelled from the clean zone.

The Focus 1000 Clean Air Operating Theatre Ventilation System is constructed from high quality zinc seal steel with epoxy paint finish to ensure a hard wearing cleanable finish. The diffuser is manufactured from stainless steel sheet perforated and formed to assist with the airflow distribution.The disposable return air pre filter conforms to Australian Standard AS 1324.
Dimension Clean Zone (nom): 1900 x 1900mm
Overall Size (nom): 2200 x 2200mm
Unit Depth 550mm
Supply Air Volume: 1500-1750L/S
Average face velocity at diffuser: 0.38m/s.
The installation of the Focus 1000 Clean Air Operating Theatre Ventilation System should take into consideration the unit mounting height, the ceiling height, the diffuser configuration and the quantity of conditioned air, the supply air temperature and the room construction. Correct installation of the system and the balancing of the supply and aid return air flow rates is important to ensure optimal performance.
Provide: 4 x 65mm Minipleat HEPA filters
Supplier: Airepure® Australia Pty Ltd
Model: AirePanel CS Filter Efficiency: rated at 99.99% min efficiency on 0.3 micron.
Note: Optional ULPA filters (99.999% min efficiency on 0.12μm particles) are available for the Focus 1000 Clean Air Operating Theatre Ventilation System.
Due to the critical nature of their end-use, Laminar Flow Grade filters are manufactured and tested in a segregated production area with its own Laminar Flow Grade air supply. Each filter is individually tested and inspected to ensure that it conforms to industry standards and meets or exceeds the expectations of the customer.
The HEPA filter (or ULPA filter if selected) combined with the Focus 1000 unique design delivers ultraclean air over the operating table downwards and outwards. A differential pressure gauge is interfaced with the BMS to monitor filter performance and allow for filter change over.

Airepure recommend replacing gel seal HEPA filters when contaminated or the loaded pressure is reached, but no longer than 5 years from manufacture date due to possible degradation of the gel. Refer to https://www.airepure.com.au/issues-affecting-gel-seal-hepa-filters/
