Designed to create a clean zone with ISO-5/Class 100 horizontal laminar airflow patters, WM series Horizontal airflow modules with HEPA ( High Efficiency Particulate Air) filter, 99.99% efficient on .3 microns, are joined together in any width combination to form one wall, then connected to a prefabricated tubular steel frame. Tunnels are determined in size by the width and height of the EPA filter horizontal laminar airflow wall modules combined with length of the tunnel enclosure Ceilings and side walls are added by using clear acrylic panels and clear vinyl curtains.

Air is totally displaced within the tunnel, from wall to wall, and ceiling to floor. The airflow moves continuously throughout the tunnel, exiting from the open end and carrying with it airborne particulate matter. Airflow modules are individually tested and certified to meet or exceed the specifications for Laminar Flow Clean-air Devices as per Institute of Environmental Sciences IEC-RP-CC-002-86

Specifications

Filter: Three-inch HEPA (High Efficiency Particulate Air) type aerosol-challenged, zero-probed. Aluminum frame minipleat design. Min. efficiency of 99.99% at .3 microns

Prefilter: 1" bonded polyfiber media minimizes surface-loading. Easily accessible from top of unit. 78% arrestance – 56–57 ASHRAE.

Airflow: Average measured clean air velocity 90 fpm (+/- 10 fpm). All measured values within +/- 20% uniformity.

Construction: Woodboard construction for minimum noise and vibration. White plastic laminate finish. Front loaded HEPA filter. Protective plastic egg crate diffuser screen in front of the HEPA filter maintains uniform air velocity within work area. Tunnel frame is 2" tubular steel with electrostatically applied enamel finish.

Electrical & Power Requirements: All electrical components are UL Approved. Standard 115V. 15Amp, 1 pH, 60 Hz. 230V also available.

Motor/Blower Assembly: High efficiency motors to reduce electrical load. Motors thermally protected & self-lubricating. Fans statically balanced to maintain constant airflow rate up to double the initial static pressure
