These cleanrooms were designed for a hospital that needed ISO7 modular cleanrooms for their USP797/800 compounding pharmacy. Their requirements included personal airlocks, cart material transfer rooms, interlocked doors, and for the cleanrooms to meet the hazardous and sterile USP797/800 standards. American Cleanroom Systems designed and installed negative and positive pressure ISO7 cleanrooms with interlocked doors, cart pass thrus, gown rooms, FRP chemically resistant modular cleanroom walls, heat welded vinyl flooring with an integral cove, HEPA filtration and a power saving system.
