The Ceiling Suspension Type (CST) room-side replaceable HEPA module is an ideal terminal filter hood for pharmaceutical and biotech cleanrooms, or wherever hoods are regularly validated for performance and leak-free operation. The CST module is available in HEPA (99.99% to 0.3μm) and ULPA (99.9995% to 0.12μm) grade efficiencies.
They may be installed in a variety of ceiling types, including tee-bar ceilings and plaster ceilings. Well suited for Class 100 “spot” applications, they may also be used to create Class 10,000 to Class 100,000 areas by locating the appropriate number of units in the ceiling. Units may also be installed for 100% ceiling coverage to achieve cleanliness levels to Class 10.
The CST features a gel-seal design offering superior protection against bypass leakage. The gel-seal interface assures a positive seal between the replaceable HEPA/ULPA filter and the hood. Its effectiveness has been proved in thousands of applications.
The CST design allows access to the filters from room-side, without disturbance to the installed housing. Bottom-loading filters along with the unique tool-less installation procedure helps make room-side filter change-out quick and easy.
CST housings and HEPA filter casings are manufactured from extruded anodised aluminium. The HEPA Filter media is manufactured of moisture resistant non-woven glass micro fibres, and is produced with a wet laid process similar to those used for the production of paper. The HEPA media is then formed into closely-spaced pleats held firmly in place with polyurethane sealant bead separators.
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/
