Infinity® Esco Air Shower Pass Box
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.
Key Benefits:
Energy Efficient
SS 304 nozzles
SS 304 base surface
Acrylic doors
Disposable prefilter
-
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 electrogalvanised steel swith 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
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.
