EdgeGARD^® Clean Bench

Horizontal Laminar Flow Clean Bench CSA Listed Underwriter Laboratories Listed Click here to download product literature

Available in Console and Space-Saver Models. Exceeds ISO-14644 ISO Class 5 (Class 100) Requirements.

Featuring Unique High Velocity Return Air Slots
EdgeGARD^® is a horizontal laminar flow clean bench which provides a HEPA filtered airflow across the work area, and a particulate-free work surface. Because only HEPA filtered air crosses the work surface, the cabinet is ideal for a range of life science and industrial laboratory and process applications where clean air and product protection is essential.

Applications

• IV admixture preparation
• Drug compounding
• Plant cell culture
• Media preparation
• Pharmaceutical procedures
• Electronic assembly
• Limited experimental research

Note: Protects product only; does not contain aerosols generated in the work area, and does not protect personnel or the environment.

Features
Each EdgeGARD^® cabinet receives 13 separate performance tests prior to shipment, including complete filter leak tests. A test report accompanies each EdgeGARD^® upon delivery.

• High velocity return air slots maximize product protection and ensure ISO Class 5 (Class 100) cleanliness.
• All models feature non-glare, all stainless steel work surfaces and side walls.
• A high performance airflow system provides laminar airflow across the work surface.
• HEPA supply filter with 99.99% minimum efficiency in capturing 0.3 micrometer particulates.
  

High-Velocity Return
Air Slots Capture Backwash Air
Cleanliness and product protection are accomplished with precise control of airflow volumes and velocities. A unique feature in the Baker cabinet design, the high-velocity return air slots, have been proven to maximize the clean bench protective capabilities.

• High velocity return air slots are located along the front edge and side walls of the work area.
• Location of the return air slots protects from backwash of dirty air into the work area created when instruments, labware or the user’s hands and arms are placed within the air stream on the work surface.
• Air is drawn into these slots at high velocity, ensuring that no unfiltered air enters the work area.
• Recovered air is HEPA filtered before being passed through the work area.
• Because recirculated air reduces the percentage of dirty air passed through the filter, overall filter life is extended.

HEPA Supply Filter With Prefilter
Because filters remove microorganisms and airborne particulates (generally called aerosols) from the air, the quality, performance and useful life of HEPA filters are critical considerations in the clean bench environment.

• Each Baker clean bench filter is scan tested for leaks and tested for overall efficiency by the manufacturer, then individually scan tested by Baker after installation to assure leak-free performance with increased trapping efficiency.
• Minimum filter efficiency is 99.99% for particulates 0.3 micrometers, increased efficiency for particulates greater and smaller than 0.3 micrometers.
• A removable protective screen is located in front of the HEPA filter. The screen protects the filter and is easily removed for cleaning or service.
• The rigid angle steel filter frame is concealed to permit only the filter media to be exposed to the work area, eliminating turbulence created by the frame effect on the rear wall.
• All air is passed through a washable, reusable Scottfoam^® prefilter which keeps the HEPA filter free of dust and larger particles, and extends HEPA filter life.

Airflow Characteristics EdgeGARD® employs a laminar airflow across the work surface. Clean air is drawn through a prefilter into the base of the console by a blower/motor . The prefilter traps dust and larger particles. The air is then pushed up the back wall plenum and through a HEPA filter at an average velocity of 100 FPM. HEPA-filtered air is directed horizontally across the work surface toward the opening.

Blower/Motor System Helps Extend Filter Life
Baker has selected an optimum blower/motor combination to assure performance and to extend filter life. The Baker blower/motor provides a constant volume of air despite increases in resistance due to filter loading, resulting in extremely long filter life as verified by simulated filter loading tests.

Extended filter life minimizes filter replacement costs. The more filter resistance the blower/motor system can overcome, the longer between filter changes.

• As particulates fill the filter media, resistance to airflow increases.
• The Baker blower/motor is a direct drive permanent split capacitor motor designed to deliver the maximum amount of filter life for each cabinet.
• The blower/motor automatically compensates for loading until the filter is fully loaded and motor capacity is reached.
• The filter need not be changed until the blower/motor system cannot deliver adequate air volume to maintain the average velocity of 100 FPM.

StediVOLT^® Motor Speed Controller Maintains Optimum Performance
The Baker exclusive StediVOLT^® motor speed controller reduces the risk of performance degradation and possible product loss due to line voltage fluctuations.

• StediVOLT^® minimizes changes in cabinet performances due to routine voltage fluctuations, as well as voltage changes caused by high-demand, brownout conditions.
• StediVOLT^® reads incoming voltage, automatically compensates for low and high voltage, and maintains proper blower speed to prevent periods of unbalanced airflow which may contribute to loss of cleanliness or product protection.

Spacious Work Area With Comfortable Lighting

• The 22” work area depth provides ample space for safe, efficient operation; heights vary from 28^1/8” to 34^1/8”, depending on model.
• Each EdgeGARD^® clean bench includes fluorescent lamps which provide up to 200 foot-candle lighting at the work surface.
• The warm, natural illumination exhibits better color fidelity.
• Adjustable leg risers (optional) permit work surface heights of 36” and 38”.

Electrical System Offers Safety And Convenience
The EdgeGARD^® electrical system is designed for safety and convenience.

• An exterior GFI duplex outlet is provided to accommodate most commonly used instruments and equipment.
• Each outlet is provided with a 5 amp self-resetting circuit breaker (7.5 amps on Space Saver Model EGBIV22).
• The outlets are on a separate circuit from the cabinet lights and blower/motor so that an overload caused by equipment will not affect cabinet function.
• For safety reasons, the EdgeGARD^® utilizes a single power cord and plug (or junction box) arrangement. This assures that a second power source is not left on if maintenance functions are necessary.
• EdgeGARD^® is UL and CSA Listed for electrical safety and integrity.

The EdgeGARD® Model EGBIV22 Space Saver is a two-foot clean bench for applications where space is at a premium. Only 28” wide overall, it is typically used for IV and nursing stations, satellite pharmacies, intensive care units and other small volume clinical or industrial situations.

Cabinet Construction Enhances Performance, Minimizes Downtime
Baker cabinet designs represent many years of experience in stainless steel fabrication and craftsmanship.

• EdgeGARD^® cabinets include a corrosion-resistant Type 304 stainless steel work surface and work area side walls.
• A hinged panel located directly below the high velocity return air slots on the leading edge of the work surface provides easy access for cleaning.
• A ½” lip at the rear of the stainless steel work surface prevents spills from entering the HEPA filter.
• The satin finish work surface diminishes harsh light reflection.
• The 18-gauge cold-rolled steel exterior cabinet is protected with a white baked enamel finish.

Caution
A clean bench is not designed to protect personnel or the environment from potentially harmful agents. The adequacy of this product for the user’s personal safety, as with any clean bench, should be determined by an industrial hygienist or safety officer.
