Operation | Features | Comparison of Standards

A clean room operates by recirculation of air through filters 20 or more times each hour. On each cycle the air is filtered to remove the dirt and dust particles.

The room is usually at a positive pressure over the surrounding area so as to ensure that any air leakage is from the room into the local environment and not the reverse. The performance of the filters is monitored to ensure a consistent performance. As the room is a closed environment, the air is conditioned to control temperature, ventilation and, if required, relative humidity. Building services such as electrical power and compressed air may be introduced to service any client machinery or equipment. Fresh air is introduced to suit operating requirements and contaminated air can be extracted, ensuring that the internal conditions are maintained at all times.

An environmentally controlled clean room operates in the same manner with a higher level of control over temperature and relative humidity. The entrance to the room can be through a lobby using insulated doors sitting within sealed frames.

Maplin will design and build a solution to the client requirement. Independent third parties validate completed rooms.
