The AC4000-Series horizontal laminar flow clean benches have a new dual-wall design, providing a convenient space for the mounting of service fixtures and electrical outlets. The thermally-welded polypropylene construction of each AC4000-series laminar flow clean bench provides a seamless interior that is easy to clean. Polypropylene is non-porous and chemically resistant, eliminating the potential for rust and allowing the enclosure to be placed in a variety of environments. Sturdy metal stands and base cabinets are available from AirClean Systems, however the ductless bench-top AC4000-Series clean benches can be placed on virtually any work surface with a 30” depth. Each updated clean bench, from the four-foot AC4000HLF to eight-foot AC8000HLF, provides the same quality construction, HEPA filtration and smooth ISO 5 horizontal laminar airflow users have come to expect from an AirClean Systems product.
