BV-48HLF-G – 48″ Wide Horizontal Laminar Flow Cabinet

Purair® Laminar Flow cabinets are designed to protect equipment and other contents of the work zone from particulates. The series is ideal for use with non-hazardous contaminants when flexible access to equipment in the work area is needed. Purair Laminar Flow cabinet series features the Air Science Multiplex™ ULPA Filtration technology which creates a clean work environment over a wide range of applications.

Purair Laminar Flow cabinets are suitable for applications that DON’T generate bio-hazardous materials and don’t need operator protection. These applications include:

  • Mycology and Food Microbiology
  • Plant and Mammalian Cell Culture
  • Clinical Pharmacy and Hospitals
  • Cleanrooms
  • Semiconductor Assembly
  • Pharmaceutical
  • Aerospace
  • Medical Device Assembly
  • Research Laboratories


  • Provides sterile work zone for aseptic techniques.
  • Air cleanliness meets and exceeds ISO Class 4.
  • All models use ULPA filters (99.999% efficient at particle sizes between 0.1 to 0.3 μm).
  • Available in horizontal or vertical flow configurations.
  • All models equipped with a stainless steel work surface.
  • Shipped fully assembled – just plug in and  use

Multiplex ULPA Filtration provides high performance protection. The main filter gasket evenly seals the filter face to prevent bypass air leakage. Our pour-in-place silicone gasket out performs traditional style stick-on “dove-tail” gasketing. The high capacity air handling system delivers flow velocity of 0.4 m/s – 0.5 m/s. Purair VLF and HLF cabinets have an ULPA filter pressure gauge to measure filter performance.


  • Incorporates external rotor blowers
  • Energy efficient design which operating costs and has low noise and vibration levels
  • Designed for desktop use or installation on the optional mobile base stand

The standard control panel features On/Off switches for blower, lighting, GFCI outlets, in addition to a Minihelic ULPA pressure gauge to measure filter performance.
The standard UV control panel includes the same features as the standard control panel with the addition of a UV lamp key.

Considerations when choosing Horizontal Airflow cabinets:

  • The airflow in horizontal flow cabinets does not directly impinge on the work surface, instead it’s smoothly drawn across it, creating less turbulence.
  • Airflow in a horizontal flow cabinet exits directly towards the user.
  • Large or tall equipment in a horizontal flow cabinet can interrupt airflow more than in a vertical flow cabinet. This may create more turbulence and possible “dead” spots where airflow is lower.

Horizontal Airflow features:

  • Purair Laminar Flow Cabinets maintain a 0.4 m/s – 0.5 m/s airflow velocity, measured 150 mm from the filter. This face velocity complies with USA and international standards for safety and performance. The ULPA filters are easy to replace with common tools.
  • Room air enters from the top of the cabinet through a disposable pre-filter; this traps larger particles and increases filter life.
  • Air is forced evenly across the ULPA filter in a stream of clean, uniform air within the work zone. This dilutes and flushes airborne contaminants from the interior.
  • A nominal filter face velocity of 0.4 m/s – 0.5 m/s ensures a sufficient number of air changes to maintain cleanliness within the work zone.
  • The purified air travels across the work zone in a horizontal, unidirectional stream and exits the work zone across the entire open cabinet front.
