Purair LF Laminar Flow Cabinet

Our popular Purair range of laminar flow cabinets are high efficiency cabinets designed to protect equipment and other contents of the work zone from particulates for applications sensitive to such contamination. These units are ideally suited for use with non-hazardous contaminants and when flexible access to the equipment in the work zone is desired. At the heart of the Purair Laminar Flow Cabinet product line is Air Science’s Multiplex ULPA Filtration Technology that creates a clean work environment over a wide range of applications.

Purair Laminar Flow Cabinets for General Applications

  • Excellent protection of equipment and materials inside the cabinet from particulate contamination
  • Rich set of options to customize cabinets for a multitude of applications
  • Easy to change filters
  • High airflow capacity

VLF & HLF Series Models

  • Purair VLF cabinets provide vertical airflow and are available in 2′, 3′, 4′, 5′, 6′ and 8′ widths for general applications.
  • Purair HLF cabinets provide horizontal airflow and are available in 2′, 3′, 4′, 5′, 6′ and 8′ widths in standard and extra tall heights for general applications
  • An optional mobile base stand is available for all models

Vertical and Horizontal Airflow Options

  • Performance of the Purair vertical and horizontal flow cabinets is the same and the choice is largely a matter of user preference
  • Horizontal flow cabinets create less turbulence at the work surface, as the airflow does not directly impinge upon it but rather is smoothly drawn across it. The airflow on the Purair vertical flow cabinets directly strikes the work surface. However, to minimize this effect, vertical laminar flow cabinets are manufactured with rear wall perforations to reduce turbulence by removing a small amount of air at the rear of the cabinet. Turbulence is a problem only when it is excessive
  • The design of vertical flow cabinets is customized more easily (at a lower cost) as required.
  • Airflow in a horizontal flow cabinet exits directly towards the user, whereas the airflow in a vertical flow cabinet strikes the work surface first and exits towards the user indirectly. It should be noted, neither style laminar flow cabinet offers any operator protection
  • Large or tall equipment in a horizontal flow cabinet will interrupt the airflow more than in a vertical flow cabinet. This may create more turbulence and “dead” spots where airflow is lower than elsewhere. Vertical flow cabinets are not so impacted by large equipment
  • In vertical flow cabinets, the ULPA filter is mounted above the work surface. This provides a larger work space, both taller and deeper, that may be appropriate for large equipment in the work zone

Air Science Purair LF Series General Purpose Laminar Flow Cabinets, complement the range of controlled environment solutions available from LAF Technologies.

  • Purair Laminar Flow Cabinets are available in 2 model types with various sizes and options for a total of 18 standard models
  • Purair Laminar Flow Cabinets are shipped fully assembled. No installation is required, just plug them in and use them
  • Products are designed for desktop use, or may be installed on an optional mobile base stand
  • The rear wall of vertical flow cabinets is perforated to reduce work surface turbulence by removing some of the airflow to the rear
  • Horizontal flow cabinets are designed with a lip on the rear of the work surface to protect the ULPA filter from spills
  • High capacity air handling system delivers flow velocity of 0.45 m/s or 90 fpm
  • Purair VLF and HLF cabinets have an ULPA filter pressure gauge to measure filter performance
  • The Air Science filters are easy to access, easy to change
  • Purair Laminar Flow products are constructed of steel with Air Science’s exclusive MICROgone antimicrobial powder finish coating. Accessories include an IV bar, service fixtures, base stand, UV lamp, and front door/cover
  • Each Air Science Purair Laminar Flow Cabinet includes features expressed through sound design and certified quality construction. Options and accessories add functional performance to meet specific applications
  • Professional quality. Air Science cabinets comply with current technical and safety regulations
