The Clean Shower provides a great microenvironment in which the airflow can be designed to achieve a specific particulate count, equivalent to any of those specified in the ISO 14644-1.
It can also be used to upgrade a section of an existing cleanroom, for example, an ISO 7 cleanroom could have an ISO 5 Clean Shower area.
These enclosures are supplied to some facinating projects but one that stands out to me for the sheer noise was installing a Clean Shower in an aircraft hanger at the end of a Euro fighter runway! The Clean Shower was used to service the pilots helmets which contain a lot of sophisticated electronics.
