A self-contained, compact, vertical or horizontal unidirectional flow module. The Envirco VLF 797/HLF 797 is an economical, multipurpose, unidirectional flow module that is completely self-contained. It provides an ISO Class 5 (Class 100) environment within the work area that complies with the latest IEST Recommended Practices. Assembly required.

Horizontal or Vertical Airflow
Using an existing work surface, the unique design of the VLF 797/HLF 797 enables quick and easy assembly to either a horizontal or vertical laminar airflow configuration. The positive pressure laminar airflow provides product protection only. Air from within the cabinet is returned to the room through the front access opening.

Standard Features
  • An ISO Class 5 environment utilizing an aerosol challenged high efficiency particulate air (HEPA) filter.
  • Easy conversion to either horizontal or vertical configurations.
  • Easy to clean touchpad controller, controls motor speed, two each fluorescent lights, and optional UV light.
  • Extruded aluminum enclosure and mil finish Fan Filter Unit (MAC 10).
  • Formed aluminum front panel with corrosion resistant polyurethane enamel finish.
  • Polycarbonate enclosed workspace on three sides.
  • Powder coated steel diffuser screen to protect the HEPA filter and maintain uniform airflow velocity work area.
  • Quiet operation (55 dBA± 3 measured 30 in. (762 mm)) from the front of the cabinet.
  • Warranty - Limited 1-year warranty
