This dumbwaiter was installed in a clean room and was used to bring uncoated micro chips from one processing floor to another. The uncoated micro chips are a very high value payload and are very susceptible to contamination from airborne particulates. The dumbwaiter unit was equipped with a Hepa Filters system that kept the dumbwaiter cab at a negative air pressure. The air was circulated from the cab through a ductwork behind and above and passed through a filter that screened out 99.99% of particles 0.3 micrometers in size.
