This Product Exceeds OSHA, ANSI and Other International Standards.
Purair Laminar Flow Cabinets maintain a 0.35-0.45 m/s (70-90 fpm) airflow velocity, measured 6"/150 mm from the filter with a uniformity of +/- 20% across the filter face. This face velocity is in compliance 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 0.35-0.45 m/s (70-90 fpm) 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.

A nominal filter face velocity of 0.35-0.45 m/s (70-90 fpm) 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 downflow 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 minimize the possibility of dead air corners in the work zone.

THE AIR SCIENCE PERFORMANCE ADVANTAGEEach Air Science Purair Laminar Flow cabinet includes features expressed through sound design and certi-fied quality construction. Options and accessories add functional perfor-mance to meet specific applications.
Professional Quality. Air Science cabinets comply with current technical and safety regulations.
Advanced Filtration. Air Science Multiplex™ ULPA Filtration provides high performance protection.
Industrial Components. The cabinet frame and work surfaces are durable and chemically resistant for long service life.
All cabinet compo-nents are clean room compatible.
Each cabinet is indi-vidually factory tested for safety and performance in accordance with international standards.
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.
VERTICAL AND HORI-ZONTAL AIRFLOW: Performance of Purair vertical and horizontal flow cabinets is the same and the choice is largely a matter of user preference.• Horizontal flow cabinets
create less turbulence at the work surface, as the airflow does not directly impinge upon it but rather is smoothly drawn across it. The airflow on the Purair vertical flow cabinets directly strikes the work surface. However, to minimize this effect, vertical laminar flow cabinets are manu-factured with rear wall perforations to reduce turbulence by remov-ing a small amount of air at the rear of the cabinet. Turbulence is a problem only when it is excessive.
• The design of verti-cal flow cabinets is customized more easily (at a lower cost) as required.
• Airflow in a horizontal flow cabinet exits directly towards the user, whereas the airflow in a vertical flow cabinet strikes the work surface first and exits towards the user indirectly. It should be noted, neither style laminar flow cabinet offers any operator protection.
• Large or tall equip-ment in a horizontal flow cabinet will inter-rupt the airflow more than in a vertical flow cabinet. This may create more turbu-lence and “dead” spots where airflow is lower than elsewhere. Vertical flow cabinets are not so impacted by large equipment.
• In vertical flow cabinets, the ULPA filter is mounted above the work surface. This provides a larger work space, both taller and deeper, that may be appropriate for large equipment in the work zone.

INTRODUCTION
The Purair PCR laminar flow cabinet
employs the Air Science Multiplex™
HEPA filtration technology to create a
safe, energy-efficient contaminant-free
environment. It is ideally suited for use
with non-hazardous contaminants
and when flexible access to the instru-
mentation in the cabinet is required.
PCR WORKSTATIONPolymerase chain reaction1 (PCR) is a simple and inexpensive technique to make multiple copies of a targeted nucleotide sequence from a DNA sample, and to amplify sequences from small samples. This technique is widely used in genetics laboratories that work with DNA and RNA.
Because PCR amplifica-tion is extremely sensitive to contamination, prevention of contam-ination requires good laboratory practices to minimize external or cross-contamination during reagent preparation, sample preparation and sample amplification.
CONVENIENCE AND CONSTRUCTION BENEFITS• Purair PCR cabinets
are available in three model sizes with various options.
• Cabinets are shipped fully assembled with standard power cords; no installation required.
• The integral UV lamp fixtures are pre-installed.
• All filters are pre-installed, easy to access and change.
• 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 (90 fpm).
• Purair® PCR cabinets are constructed of steel with a microbial powder finish coating.
The optional stainless steel work surface includes lips on all four sides to contain spills.
1 Polymerase chain reaction (PCR) is a patented process owned by Hoffman La Roche.

THE AIR SCIENCE PERFORMANCE ADVANTAGEEach Air Science fume hood includes features expressed through sound design and certified quality construction. Options and accessories add functional perform- ance to meet specific applications.
Professional Quality. Air Science fume hoods comply with current technical and safety regulations.
Multiplex Filtration. The Air Science Multiplex Filter offers a range of options for high perform- ance protection.
Industrial Components. The cabinet frame and work surfaces are durable and chemically resistant.
Reliability. Internal systems are isolated from fumes, extending product life.
Purair PCR cabinets incorporate energy-efficient ebmpapst™ permanently lubricated direct drive centrifugal blowers for maximum operational savings, low noise and minimal vibration.
Purair® PCR-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 front area of the cabinet.
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.

AIR SCIENCE MULTIPLEX FILTRATION TECHNOLOGY The Multiplex filtration consists of a pre-filter and main HEPA filter. The mechanical design enhances safety, convenience and overall value.
• The disposable pre-filter is accessible from the exterior top of the cabinet.
• A filter clamping mechanism allows for the filter to be easily installed and ensures an even seal at the filter peripheral face at all times to prevent bypass leakage.
MULTIPLEX FILTRATION SYSTEM SUMMARYPre-Filter Disposable polyester fibers with 85% arrestance.
HEPA A self-contained filter designed to physically capture particles larger than 0.3 microns (HEPA) or 0.12 microns (ULPA).
Air Science uses long-life Camfil Farr HEPA filters without aluminum separators to increase filter efficiency, mini-mize the potential for leakage and increase filter life.
The optional Monitair microprocessor controller monitors and displays cab-inet operating parameters, airflow, containment, and filter condition; emits audio and visual alerts if condi-tions become unsafe, all on a LCD display.
