A self-contained, compact, horizontal or vertical unidirectional flow module. The Envirco VLF 797/HLF 797 is an economical, multi-purpose, 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.

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 unidirectional 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.
  • Single electrical outlet, 115V, 15 Amp, flush mounted on the front blower housing.
  • An extruded aluminum cabinet and stand.
  • A formed aluminum front panel with corrosion resistant polyurethane enamel finish.
  • Powder-coated steel diffuser screen protects the HEPA filter and maintains uniform airflow velocity within the work area.
  • Quiet operation (55 dBA± 3 measured 30 in. (762 mm)).
  • Warranty - 1 year limited warranty

Construction

Aluminum cabinet with front panel finished in corrosion resistant polyurethane enamel.

Filters

Aluminum framed High Efficiency Particulate Air (HEPA) type, with a minimum efficiency of 99.99% at 0.3 micron, aerosol challenged.

Prefilter

Washable type, polyurethane foam - 30% ASHRAE.

Motor/Blower Assembly

Direct drive, continuous duty 1/5 Hp, with sealed-for-life bearings and inherent overload protection. Motor/blower assembly is electronically balanced (dynamically) and mounted on vibration dampening rubber mounts. Motor/blower assembly is designed to provide rated airflow through a 50% increase in initial static pressure.

Speed Controller

Solid-state speed control with RFI suppression for adjusting airflow velocity, which utilizes an easy-to-clean membrane touchpad controller.

Electrical1

Standard 15 Amp, 115V, single phase, 60 Hz, rubber covered cord with 3-prong grounded plug. Single electrical outlet flush mounted on front blower housing. Optional fluorescent lighting fixture provides 90 foot-candles at the work surface.
1 Amps @ 115V/60 Hz


Options
Shroud to cover MAC 10 unit.

Ultra-Violet Light Option - An optional UV light is available for surface decontamination. An over-sized polycarbonate front panel is utilized to prevent accidental exposure of UV light to personnel.
