PPurair FLOW series laminar flow cabinets are designed to protect the work surface, products and materials from particulate contamination. Room air passes through a HEPA filter then uniformly by laminar flow through the cabinet interior to protect the work from unfiltered air. The airflow is oriented to exhaust airborne particulate introduced by the user.
 
The Purair FLOW series product line employs the Air Science exclusive Multiplex HEPA filtration technology to sustain the contamination-free environment.
 
FLOW™ Benefits
  • Vertical laminar flow with HEPA/ULPA filtration protects materials inside the cabinet from particulates.
  • High airflow capacity
  • Configurable with a broad range of options customized to your specific application.
  • Easy-to-change filters.
  • Available in 2', 3' and 4' widths

Applications
Purair® FLOW™ Series cabinets offer a proven level of ISO Class 4 product performance at an economical cost. These cabinets are intended for use in non-hazardous applications where biological or biohazard byproducts are not generated and user protection is not required. A range of Air Science innovations are integrated into the clean, simple, low-maintenance design offering  flexible access to the interior work area. Typical applications include:
 
  • Mycology and Food Microbiology
  • Plant and Mammalian Cell Culture
  • Clinical Pharmacies and Hospitals
  • Clean Rooms
  • Semiconductor Assembly
  • Pharmaceutical Production
  • Aerospace Contamination Control
  • Medical Device Assembly
  • General Research Protocols
 
Features
  • Vertical laminar flow with HEPA/ULPA filtration protects materials inside the cabinet from particulates.
  • High airflow capacity.
  • Configurable with a broad range of options customized to your specific application.

The Air Science Performance Advantage
Each Purair 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.
  • Advanced Filtration. Air Science Multiplex HEPA filtration provides high performance protection.
  • Industrial Components. The cabinet frame and work surfaces are durable and chemically resistant.
  • Reliability. Internal systems are isolated from contamination, extending product life.
 
Convenience and Construction Benefits
Purair® FLOW™ Cabinets are available in 3 model sizes with various options.
  • Cabinets are shipped fully assembled with standard power cords; no installation required.
  • Products are designed for desktop use, or may be installed on an optional base stand or mobile cart.
  • The high capacity air handling system delivers flow velocity of 0.45 m/s or 90 fpm.
  • Purair® FLOW™ cabinets are constructed of steel with a microbial powder finish coating.
 
PURAIR® FLOW™ AIRFLOW PATTERN
Purair FLOW-36 shown with Multiplex filtration system.
 
Room air enters from the top of the cabinet through the disposable pre-filter where larger particles are trapped, increasing the service life of the main HEPA filter.
 
Air is forced evenly across the HEPA filter to deliver a flow of pure, uniform air within the work zone to dilute and flush airborne contaminants from the work area.
 
A nominal filter face velocity of 0.45 m/s (90 fpm) ensures that there is sufficient number of air changes within the work zone to eliminate cross contamination and to maintain optimum cleanliness.
 
Purified air travels across the work zone to the work surface in a vertical, unidirectional downflow stream, and then exits the work zone across the open cabinet front.
 
A. The main filter is easy to replace; no tools required. The filter clamps tightly against the filter gasket to prevent filter bypass and to maintain filter integrity.
