Although the idea of a cleanroom may seem right out of science fiction, clean and controlled environments are actually used by a wide range of industries. From their more obvious uses in medical facilities to their necessity in integrated circuit manufacture, cleanrooms provide an essential role in modern production and research.

At its most basic level, a cleanroom is just what it sounds like: an area kept free of contaminants.

There are 5 key elements for the control of airborne particulate matter:

• Preventing entry of particulate matter - This is accomplished by filtration of the air entering into the cleanroom
• Purging of particulate matter - The air handling system changes the air in the room and thus removes particulate matter generated within the room
• Prohibiting the generation of particulate matter - Cleanroom materials and finishes are selected for their resistance to particle generation
• Protecting the product from impact and settling of particulate matter - The low level of particulate matter in cleanrooms contains a majority of the smaller size particles, which settle out very slowly. These smaller particles have a very long "life" in the air
• Providing an area for the cleaning of parts and personnel - Everything entering the cleanroom is cleaned, so that as little contamination as possible is added to the room atmosphere by transfer from dirty objects

Having given due consideration to the above factors, it is possible to achieve and sustain the desired cleanliness goals. This six-hour course provides an overview of cleanrooms and discusses the key HVAC design aspects applicable to cleanrooms.
