BV-24VLF – 24″ Vertical 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
- Semiconductor Assembly
- 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.
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 an 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
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.
Consideration when choosing Vertical Airflow:
- 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.
Vertical Airflow Features:
- 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 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 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.
