Air Flow Systems
There are basically three different air flow systems in cleanrooms: pressurized plenum, ducted supply and ducted return, and ducted supply and open return. Pressurized plenum essentially means you pump the air into the plenum, push it through the filters and down on into the cleanroom. With a ducted supply and ducted return, you’re doing just that; you’re ducting the air delivered to the cleanroom and you’re ducting the air back out of the cleanroom.
Choosing Cleanroom Doors & Ceilings
Cleanroom door selection is an interesting topic because from a cleanliness standpoint, the decisions are somewhat easy. In a pharmaceutical environment you’re concerned about cracks or crevices in the door and how microbial growth can result from that. But the decision process for a cleanroom door is more influenced by what you need from the entry and exit of people, personnel and materials, than on how a door relates to the cleanliness level.
Cleanroom Construction Materials
The question of modular versus conventional clean room construction is increasingly common in high-tech industries, and one that may have a different answer depending on each individual project. Speed to market, however, is critical for almost all manufacturing companies, and it’s particularly important for the pharmaceutical and biopharmaceutical industries, which need to maximize the patent protection period after what is usually a long and expensive product development cycle. It’s also crucial for the microelectronics industry where technology changes on a near-daily basis.
