Occasionally we hear the term “cleanroom” used for a winding area that is physically isolated from the remainder of a service center (Figure 1). The main purpose of such an enclosure is to prevent windings and winding material from being contaminated with any dust and dirt (Figure 2) that may be in other parts of the service center. Some service centers construct these enclosures because they strive to provide the cleanest practical environment for winding work, and some also use the enclosure for the bearing installation process. Cleanroom type enclosures can also benefit facilities by helping minimize quality problems and increase the volume of acceptable product.

Here we will explore the distinction between a controlled environment and a cleanroom, the requirements for both, and provide details to help you determine if you want to add a controlled environment or a cleanroom to your facility.
