Pass box overview

The pass box is a crucial piece of equipment in cleanrooms, typically mounted on walls between cleanrooms of varying levels or between cleanrooms and non-clean areas.

Its primary function is to facilitate the transfer of specific materials between these areas, thereby minimizing the frequency of door openings and decreasing particle emissions within the cleanrooms.

Environment

Before purchasing a pass box, customers should clarify the intended environment for its use. Factors to consider include the need for sterilization, appropriate size, and whether a dynamic or static pass box is required.

Pass box material

Selecting the appropriate material is crucial. Stainless steel is recommended for its durability and longevity. Its smooth surface facilitates easy cleaning and maintenance.

For environments where cleanliness requirements are not as stringent, cold-rolled steel sheets offer a more economical option.

Some manufacturers opt for a combination of stainless steel for internal parts and cold-rolled steel sheets for external parts to balance purification functionality and cost-effectiveness.

Transferred items

The size of the items to be transferred is a crucial factor in selecting a pass box for the cleanroom. Pass box sizes can be customized according to customer requirements, although this may entail longer lead times. For standard needs, pass boxes with dimensions of 500x500x500, 600x600x600, or 700x700x700 are readily available and suitable.
