Esco Airstream Horizonal Laminar Flow Clean Bench

  • Model AHS-6B2
  • 90 FPM
  • New filter included
  • 90-day warranty 

The 100% stainless steel interior provides better cleanability of the work zone. Class 100 (US Fed Std 209E) product protection with ULPA filter 99.999% at 0.12 microns and pre-filter. Built-in tempered glass sides, external rotor motor system, variable speed control. 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. Built-in warm white, electronically ballasted, 5000k lighting provides excellent illumination of the work zone and reduces operator fatigue. The reliable lighting system is zero-flicker and instant start. The removable perforated filter diffuser on all models provides protection to the filter and improves airflow uniformity.

On the horizontal flow bench, the diffuser provides additional protection in the event of an accidental spillage and is easy to clean. High quality ULPA filters, utilizing an improved mini-pleat separation technique to maximize surface area, improve efficiency and extend filter life. Filters operate at a typical efficiency of >99.999% at 0.1 to 0.3-micron sizes, providing superior product protection over conventional HEPA filters. A built-in solid-state variable speed controller (infinitely adjustable from zero to the maximum setting) with built-in RFI and noise filters is superior to conventional "step" controllers.

Room air is taken in from the top of the clean bench through a disposable pre-filter with 85% arrestance; this serves to trap larger particles and increase the lifespan of the main filter. Air is forced evenly across the ULPA filter(s); the result is a stream of clean laminar air within the work zone of the clean bench; this dilutes and flushes all airborne contaminants from the interior.  A nominal filter face velocity of 0.45 m/s or 90 fpm ensures that there is a sufficient number of air changes within the enclosed area of the clean bench in order to maintain cleanliness.
