ValuLine™ all-polypropylene models
This versatile laminar flow hood gives you a particle-free work environment on any available work surface.
  • Portable, economical system converts any benchtop surface into a laminar flow station
  • HEPA fan/filter units provide vertical flow of micro-filtered air to meet ISO cleanliness requirements (order separately)
  • Provides air flow speed 109 feet/minute (0.55 m/s) measured with HEPA filter; internal baffling plates and anodized aluminum diffuser panel ensure uniform air speed across the work area
  • Quiet operation: 50 dBA measured 12" (305 mm) from filter face
  • Available with many application-specific wall panels, including polycarbonate, static-dissipative PVC and stainless steel; all polypropylene model is ideal for use in the presence of harsh chemicals
  • Work surfaces available to meet any cleanliness requirement
  • Standard widths to 72" (1829 mm), with 24" (610 mm) or 30" (762 mm) depth; high-clearance model available for large process equipment
  • Standard outside height of 40.8" (1036 mm)

Select the panel material for your application. Polycarbonate wall panels afford full visibility of work in progress and resist a broad range of chemicals, including cleaning agents. Static-dissipative PVC panels provide broad chemical resistance and prevent the buildup of static, making it ideal for processes involving delicate electronics or powders that are prone to clinging to surfaces. These panels slide into an all-stainless steel frame that provides durable support for the Fan/Filter Units (sold separately). The stainless steel-walled hood is built as one solid piece of stainless steel (no separate frame), offering the highest cleanliness and durability.

Each model also includes recessed LED lighting and a hinged access shield that increases air speed by restricting the air exhaust. Hood orders are shipped completely assembled, ready for operation.
