HEPA, Pre & Fine Filters
CLIMA Airflow Systems supplies the complete range of air filtration products — from coarse Pre-filters at the fresh air intake through to terminal HEPA filters at the clean room supply point. A correctly staged multi-filter strategy is the most cost-effective way to achieve and maintain ISO clean room classification while minimising HEPA replacement costs. CLIMA advises on filter selection, grades, and stage sizing during system design, and supplies replacement filters for any AHU, FFU, or terminal housing application across all major filter grades from G4 through to ULPA U16.
