One of the first questions is modular or drywall? Modular offers the most flexibility. It will allow you to expand as your business expands. Drywall has its economical advantages but is quite permanent, and can be more expensive if all cost variables are factored in. Let’s look at the details:

Wall panel skins are the surfaces of the wall panels that are exposed. Whattype of modular panel skins should your cleanroom be constructed of? To answer this question, you need to assess the purpose of the cleanroom along with how you plan on cleaning your cleanroom. Are you going to use a wet or dry agent or both?

Generally using a system that needs supporting skin structure presents the following pros and cons. It allows the use lower class material not exposed to the clean areas, thus reducing costs. In case of scratches or wall chipping low class material exposed to the environment

Some modular wall manufacturers’ products include panels without insulation. Avoid use of product that may lead to fumes in case of fire, cost and easier use of wall interior for utilities or electrical wiring.

There’s really not an enormous difference between a single pass and a recirculating cleanroom, it just has to do with the preciseness of how you control the return. In any cleanroom you’re taking the air and you’re pushing it down through the room, and then you’re transferring it out of the room. Now the difference between a single pass and a recirculating cleanroom is what you do with that air once it’s purged out of the room. For instance, are you just going to control the return back to the plenum, or are you going to let that air wash into the surrounding areas? The decision based on which design you use has to deal with the preciseness of your control.
