Filtered fume extraction

Laminarflow fumehoods

Purair® Laminar Flow Hoods are a series of high efficiency products designed to protect equipment and other contents of the work zone from particulates, for applications sensitive to such contamination. The series includes Laminar Flow Fume hood (VLF) cabinets and Laminar Flow Fume hood (HLF) cabinets and is 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 Hood product line is the Air Science Multiplex™ ULPA Filtration Technology that creates a clean work environment over a wide range of applications.

  • Horizontal laminar flow vs Vertical laminar flow.

  • Virtical Laminarflow Fume hoods
  • More often have filters located on the back wall. Filtered air is then passed horizontally from the rear, straight across the work surface.
  • Laminar Flow Fume hood
  • Typically have a top or ceiling mounted filter.
  • Air exiting the filter media passes from the unit ceiling and then across the work surface, sweeping particles out of the enclosure as it goes.
  • Both tyes of filteredfume hoods

    provide unidirectional airflow that protects products on the work surface against particles and particulates. The choice for your specific needs can come down to personal preferences but there are a benefits unique to each model.

  • Purair® LF Series Other Features
  • Visibility
  • Side windows allowing ambient light into the chamber providing users with optimal visibility for the viewing of contents. (Not available on stainless steel models.) Sterile Compounding Compliant.

    When used according to best practices, the LF Series cabinet encourages compliance with criteria set forth by USP 797 for sterile preparation in pharmaceutical compounding of nonhazardous agents. These include injectables, IV admixtures, pastes and ointments and irrigating solutions which are protected by filtered air over the work surface in a laminar flow.

    Construction

    Choose from standard powder coated interior with stainless steel work surface and side windows or optional stainless steel interior (-SS model). Available in 120V, 60Hz, and 230V, 50Hz models.
