Laminar Flow Clean Bench Hood

Product Overview

The Purair FLOW Series laminar flow cabinets deliver simple, effective protection for samples and work processes. These vertical laminar flow cabinets provide sterile work zones for aseptic techniques while maintaining uncompromised performance at an economical price. Designed to protect the interior work zone from particulate contamination, the FLOW Series employs exclusive Multiplex HEPA Filtration technology to sustain a contamination-free environment.

HEPA filtered air passes uniformly through the cabinet interior via vertical laminar flow, oriented to prevent introduction of airborne particulates during normal use. ISO Class 5 air quality is maintained through downward laminar flow that provides gentle airflow throughout the cabinet. The clean, simple, low maintenance design offers a comfortable workstation and may be bench mounted or positioned on a mobile bench.

Energy Efficiency

The single EC blower motor delivers exceptional energy savings, consuming just 37–115 watts depending on cabinet size. This makes the Purair FLOW one of the world's most energy efficient laminar flow cabinets, assuring lower cost of ownership throughout its service life.

Applications

Vertical laminar flow cabinets are intended for use in non-hazardous applications where user protection from biologicals or biohazardous byproducts is not required:

• Mycology and Food Microbiology
• Plant and Mammalian Cell Culture
• Clinical Pharmacies and Hospitals

Design and Construction

Cabinet Construction

Professional quality cabinets comply with current technical and safety regulations. The cabinet frame and work surfaces are comprised of industrial components that are durable and chemically resistant with a microbial powder finish coating. All models are available in 120V, 60Hz or 230V, 50Hz configurations.

Visibility and Access

Clear back and side panels allow ambient illumination into the chamber and provide users with an unobstructed view of its contents, offering 360 degree visibility.

Component Highlights

• Control Panel: On/Off switch for simple operation of blower and light
• Main Filter: HEPA filter with 99.97% efficiency for 0.3 micron particulates (ULPA optional)
• Pre-Filter: Disposable polyester fiber pre-filter with 85% arrestance
• Blower Motor: Energy-efficient centrifugal fan for maximum operational savings, low noise and minimal vibration
• Lighting: Compact LED cabinet lamp located away from laminar flow area
• Pass Through Ports: Two standard knock-out rear-wall ports for safe routing of instrument cords, cables, and leads
• Filter Door Lock: Prevents unauthorized removal or accidental exposure to saturated filters
• Filter Clamp: Wide knob screw compression clamps conveniently located forward of the assembly secure the filter to the plenum with even pressure to assure a tight seal and simplify filter removal and replacement

Multiplex Filtration System

Airflow Path

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 air within the work zone to dilute and flush airborne contaminants. An average airflow velocity of 0.30 m/s (60 fpm) at initial setpoint ensures sufficient air changes within the work zone to eliminate cross contamination and maintain optimum cleanliness. Purified air travels across the work zone to the work surface in a vertical downflow stream and exits across the open cabinet front.

Filter Configuration

• Pre-Filter: Disposable polyester fibers with 85% arrestance; may be replaced while unit is in operation
• Main Filter: Self-contained filter designed to physically capture particles larger than 0.3 microns (HEPA) or 0.12 microns (ULPA); easy to replace with no tools required

The unique filter clamping mechanism allows for easy installation and ensures an even seal at the filter peripheral face at all times to prevent bypass leakage. The filter assembly is easy to access and easy to change. Air Science uses long-life HEPA filters without aluminum separators to increase filter efficiency, minimize the potential for leakage and increase filter life.
