View Model/Dimensions & Sample Drawings

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.

Construction:

  • 1/2″ white stress relieved polypropylene.
  • Heat welded support seams for additional strength.
  • Support ribs under work surface.
  • Front loaded HEPA filter.
  • Counterbalanced Vertical sash (clear polycarbonate).
  • Vented storage cabinet with leg levelers – SEFA Tested
  • Work surface perforated front and rear for laminar flow, removable for cleaning.
  • Rear exhaust plenum terminates at 10″ – 14″ dia. collar.
  • Fabricated with all plumbing, instrumentation and electrical complete (as per option requested).
  • Includes Polypropylene Hinges, Handles, Screws & Sash rope.

Airflow:

Requires facility exhaust. Average clean air velocity 80 fpm (+/-20 uniformity). Negative resistance, .50 IWG

Filter:

Three inch HEPA (High Efficiency Particulate Air) type, aerosol challenged, zero probed. Aluminum frame mini-pleat design. Minimum efficiency of 99.99% at .3 microns. (ULPA filters available)

Prefilter:

1″ bonded polyfiber media minimizes surface-loading. 78% arrestance —- 56-57 ASHRAE

Electrical & Power Requirements:
