The Esco Air Shower Pass Box (EAS-PB) is a cost-effective solution in controlling the ingress of contamination into cleanrooms and its surrounding facilities. Its high velocity ULPA-filtered air jets ensure that all materials are scrubbed off of possible particulates that might affect the sterility of the process and final products.

Features

  • Built-in air shower significantly reduces surface contamination on materials entering or exiting the controlled environment.
    • Materials entering or exiting the controlled environment are "scrubbed" by high velocity ULPA-filtered air jets with velocities of 18-30 m/s (3543-5906 fpm).
    • An array of stainless steel nozzles direct high-velocity jets within the chamber.
  • Contaminated air is then drawn through the base within the unit, filtered and recirculated.
  • Air shower duration is adjustable up to 2 mins. Standard factory pre-set is 12 seconds.
  • Electrical interlocking door mechanism.
  • The air shower is constructed of electrogalvanized steel with white oven-baked epoxy-polyester Isocide™ antimicrobial powder coated finish.
  • The pass box base surface is constructed of perforated stainless steel 304, making it easy to clean.
  • Polycarbonate viewing windows provide a clear view of the internal chamber.
  • Esco Air Shower Pass Boxes use German-made ebm-papst® permanently lubricated, centrifugal motor/blowers with external rotor designs.
    • Selected for energy efficiency, compact design, and flat profile, the completely integrated blower assembly optimizes motor cooling, with unified rotating parts and overall component balance for smooth, quiet, vibration-free operation.

Key Benefits


  • Energy Efficient
  • SS 304 nozzles
  • SS 304 base surface
  • Acrylic doors
  • Disposable prefilter

Principle


  • Air is forced by the blower(s) through ULPA filter(s) which are >99.999% efficient against particles of 0.3 microns.
  • Filtered air is ejected through nozzles at high velocities into the chamber. These turbulent air streams disperse particulate matter on all surfaces.
  • Dispersed particulate matter migrate with the air stream towards the lower areas in the air shower chamber.
  • The air is continuously filtered and recirculated.

Accessories


  • Optional UV lamp
  • Full stainless steel construction
