Features of the HKURCEID - Air Handling

The air in the facility passes through both pre-filters (Figure 1) and HEPA filters (Figure 2) contained in a filter housing above the work area (Figures 3 and 4).

The pressure differentials in the laboratory are measured using Magnehelic gauges (Figure 5) and the pressure is shown outside the laboratory on a panel (Figure 6).

The HEPA filters are tested at regular intervals (Figures 7 and 8).

The integrity of the whole facility was tested using a pressure decay test (AS/NZS 2243.3: 2002) (Figure 9). The variable speed fans that control the air supply are located in a plant room outside the secure facility. This makes access for servicing straight forward.
