Designed and Built for Enhanced Usability

  • Esco laminar flow clean benches incorporate a number of features to ensure operator comfort and enhanced productivity.
  • The clean bench work surface is constructed of stainless steel, making the work zone easy to clean. The interior surface will not chip, rust or generate particles.
  • The spillage-retention work top design with a recessed central area ensures that all liquid spills are contained.
  • The ergonomically designed work surface with a curved front edge is designed for maximum operator comfort. A raised edge at the back of the work zone prevents spills from damaging the filter.
  • The instant-start 5000k warm white lighting operates on an electronic ballast to reduce heat, improve comfort and conserve energy.

User-Friendly Control System

  • Built-in solid state variable speed controller is superior to conventional "step" controllers and offer infinite adjustment from zero to maximum setting.
  • Standard cabinet control system consists of separate switches for blower, lights, UV light (UV light switch is interlocked with the light and blower switch for enhanced safety), and socket plus a pressure gauge for filter monitoring.

Enhanced Filtration System

  • The enhanced filtration system on the GAH-B series is designed to provide the highest level of air quality within the work zone, meeting all relevant standards (see technical specifications for details).
  • All Esco laminar flow clean benches provide ISO Class 3 air cleanliness within the work zone as per ISO 14644.1, significantly cleaner than the usual Class 5 classification on cabinets offered by the competition.
  • High quality ULPA filters, utilizing an improved mini-pleat separation technique to maximize surface area improving efficiency and extending the life of the filter. ULPA filters operate at a typical efficiency of >99.999% on 0.1 to 0.3 micron sizes, providing superior protection over conventional HEPA filters.
  • An additional disposable pre-filter on all models traps large particles in the inflow air prior to reaching the main filter, protecting it against damage and prolonging its life.
  • Intergral filter metal guard on the ULPA filter prevents accidental damage to the filter media; seamless filter gasket is permanently molded on the filter frame and will not deteriorate over time; aerosol (DOP/PAO) challenge test port included.

Airflow

  • "Blue Box" ULPA-Filtered Air
  • "Red Box" Unfiltered / Potentially contaminated Air
  • "Green Box" Room Air / Inflow Air




Controller

  • Rocker Switch and Minihelic Gauge
  • Built-in solid state variable speed controller is superior to conventional "step" controllers and offer infinite adjustment from zero to maximum setting.
  • Standard cabinet control system consists of separate switches for blower, lights, UV light (UV light switch is interlocked with the light and blower switch for enhanced safety), and socket plus a pressure gauge for filter monitoring.

The Highest Quality Cabinet Construction

  • All Esco products are manufactured for the most demanding laboratory applications.
  • All components are designed for maximum chemical resistance and enhanced durability for a long service life.
  • The main body of the clean bench is constructed of industrial-grade electrogalvanized steel.
  • All cabinet components are clean room compatible.
  • Isocide eliminates 99.9% of surface bacteria within 24 hours of exposure.
  • Transparent tempered glass side panels enhance visibility and create a more comfortable work environment for the operator as opposed to conventional stainless steel or painted steel sides.
  • Tempered glass is scratch and abrasion resistant, does not create particulates, and is easy to clean.

Blower Efficiency

  • Esco laminar flow clean benches incorporate permanently lubricated direct drive centrifugal blowers.
  • The energy efficient external rotor motor design reduces operating costs and has extremely low noise and vibration.
  • The intelligent blower system compensates airflow as the filter becomes loaded, ensuring optimum efficiency and product protection.

Designed and Built to Exceed Safety Criteria

  • All components used in Esco products meet or exceed all applicable safety requirements.
  • Each cabinet is individually factory tested for safety and performance in accordance with international standards.
  • UL listed or UL recognized, electrical components ensures superior electrical safety for the operator.
  • All Esco laminar flow clean benches meet general safety requirements set by independent testing laboratories (see technical specifications for details).
  • All models have been type tested to the EN 12469:2000 for cross contamination and product protection using microbiological testing methods.
