OEM & ODM Air Shower Pass Box Clean Equipment

 

Controlling the ingress of particulate contamination into cleanrooms and other controlled environments is paramount in order to maintain the integrity of products and processess. Personnel traffic is the most important factor which must be controlled. Our Pass Boxes and Transfer Hatches are a cost effective solution as they allow materials to be transferred into the controlled environment without actual personnel movement. They may also be used to protect the external environment from egress of contamination, for example, in biological safety laboratory applications.

 

Key Benefits:

• Cost Effective
• Energy Efficient
• SS 304 nozzles
• SS 304 base surface
• Acrylic doors
• Disposable pre filter

   

Main 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 HEPA/ULPA filtered air jets with velocities of 25 m/s (4921 fpm). Contaminated air is then drawn through the base within the unit, filtered and recirculated.
• An array of stainless steel nozzles direct high-velocity jets within the chamber.

Air Shower Pass Box Construction:

• Robust construction qualifies the air shower pass box for the most demanding controlled environment applications. The unit is fully assembled and ready to install and operate when shipped. All components are designed for maximum chemical resistance and enhanced durability for a long service life.
• Electrical interlock maintains cleanroom integrity by preventing both doors from being opened at the same time.
• The air shower is constructed of SUS304 with an abrasion resistant oven-baked powder coated finish.
• The pass box base surface is constructed of perforated stainless steel, making the work zone easy to clean.
• Acrylic doors provide a clear view of the internal chamber.

Blower and Filtration Systems:

• Zhuowei Air Shower Pass Boxes use Taiwan made 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. Weight is equally distributed to all bearings to extend bearing life.
• ULPA filter(s) provide 99.999% typical efficiency for particle sizes at 0.1 to 0.3 microns. The filters meet the recommended practice for HEPA performance (USA), and EN 1822 for H13 performance (EU).
• A disposable pre-filter with 85% arrestance extends the life of the main filter.
• Optional UV lamp, must be factory fitted, specify when ordering.
• Air is forced by the blower(s) through ULPA filter(s) which are 99.999% efficient against particles of 0.1 to 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.
