PVE Series – Polypropylene Vertical Laminar Flow Workstation
Applications:
Semiconductor, Microelectronics, Waste & Water Treatment, Research & Trace Metal Labs, Chemical Analysis, Pharmaceutical Manufacturing, Curing, Etching Processes, Plating Processes, Cleaning Processes, Photonics
Description:
Designed as an exhausting vertical laminar airflow clean workstation, it is to be used when toxic odors & fumes are present. Intake air passes through a HEPA filter (99.99% efficient on .3 microns) providing an ISO 5 / Class 100 airflow into the work chamber & downward through the perforated work surface. Air is then exhausted through the internal rear wall & ducted for discharge at the top of the unit. A remote exhaust air system is required to balance the work chamber’s airflow pattern. The use of polypropylene offers immunity to corrosion, resistance to acids & solvents, non-conductive properties, with minimal maintenance. Unit includes a vented, full depth base cabinet. Individually tested & certified to meet (exceed) the specifications for Laminar Flow Clean Air devices as per Institute of Environmental Science- IES-RP-CC-002-86, SEFA 8P.
