TFP HEPA Filter Modules are terminal HEPA filter plenums designed for ceiling installation in new cleanroom construction, or for upgrading existing rooms. Modules are suitable for use in ceilings of plasterboard or laminated-panel construction, and are supplied with fittings to facilitate installation.
A range of configurations and sizes enables the system designer to select modules for any application. Low-profile modules are recommended for installations where ceiling space is restricted.
Fan-assisted modules have been developed for applications where the existing air supply system does not have the fan capacity to overcome the additional static pressure of HEPA filters. Variable-speed fans enable airflows to be regulated to meet requirements for room pressure and airflow, and to compensate for filter dust loading.
An ultra-quiet version of low-profile fan-assisted modules with special acoustic treatment is available for applications where noise level is highly critical.
Sophisticated manufacturing and assembly environments such as Class 350 cleanrooms require the installation of HEPA filters at the point of air entry to the room. This requirement is set out in Australian Standard AS1386, Cleanrooms and clean workstations, and the Code of Good Manufacturing Practice for Therapeutic Goods – Medicinal Products published by the Department of Community Services and Health.
Typical applications include the manufacture and packaging of sterile pharmaceuticals, medical devices and electronics components; hospital operating theatres and hospital-pharmacy cleanrooms.
