Polypropylene Lab Equipment

PVE Series: Polypropylene Vertical Laminar Flow Workstation

Applications: Trace Metal and Research Labs,Semiconductor, Microelectronics, Waste & Water Treatment,  Chemical Analysis, Pharmaceutical Manufacturing, Curing, Etching Processes, Plating Processes, Cleaning Processes, Photonics.

Description: PVE Series offer Product protection within the work chamber - filtered air (ISO 14644) AND Operator protection by exhausting to the buildings exhaust system (tested to ASHRAE110) .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 or ULPA filter (99.99% efficient on .3 microns) providing an ISO 5 / Class 100 or better - 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; designed to meet national safety standards - NSF /ANSI 49 - the safety of products and personnel in the lab.
