BV-60VLF – Vertical Laminar Flow Cabinet
Purair® Laminar Flow cabinets are designed to protect equipment and other contents of the work zone from particulates. The series includes Vertical Laminar Flow (VLF) cabinets and Horizontal Laminar Flow (HLF) cabinets and is ideally suited for use with non-hazardous contaminants when flexible access to equipment in the work zone is desired. At the heart of the Purair Laminar Flow cabinet product line is 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 generate no bio-hazardous materials and do not require operator protection.

• 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.
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.
Laminar Flow cabinets incorporate an ebm-papst external rotor blowers. The energy efficient design reduces operating costs and has low noise and vibration levels. Products are designed for desktop use or installation on the 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.
Purair Laminar Flow cabinets are available in vertical and horizontal configurations with various sizes and options for a total of 36 models to choose from in 6 different widths. Select from standard powder coated interior or stainless steel interior (-SS models).
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.
• The airflow on the Purair LF Series vertical flow cabinets directly strikes the work surface.
• Vertical laminar flow cabinets are manufactured with rear wall perforations that remove a small amount of air at the rear of the cabinet to reduce turbulence.
• In vertical flow cabinets, the ULPA filter is mounted above the work surface which provides a taller and deeper work space. This allows for larger equipment in the work zone without interrupted airflow.
• Vertical flow cabinets are more easily customised to specific applications.
1. Room air enters from the top of the cabinet through a disposable pre-filter; this traps larger particles and increases filter life.
2. Air is forced evenly across the ULPA filter in a stream of clean, uniform air within the work zone. This dilutes flushes airborne contaminants from the interior.
3. 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.
4. The purified air travels down to the work zone in a vertical, unidirectional down-flow stream, exiting the work zone across the entire open cabinet front area after deflecting off the work surface. Rear wall perforations are designed to reduce work surface turbulence and minimise the possibility of dead air corners in the work zone.
