A cleanroom is an essential facility for any reputable data recovery specialist because of the close tolerance mechanisms found inside storage media.
They are used in situations where environmental variables such as temperature, humidity, airborne contaminates etc. can adversely affect the critical repair of sensitive electronic components.
The cleanroom is a perfectly sealed environment designed to prevent migration of contaminants onto the highly sensitive media. State of the art filtration systems and air management equipment creates positive air pressure inside the chamber to provide the highest level of protection against potential contamination.
