In clean rooms and in laboratories, a primary process that has to occur under dust and/or germ-free circumstances takes place. The concentration of particles in the air has to be controlled, as well as other parameters such as temperature, humidity and pressure. These rooms are often airtight and the applied materials for the walls, floors, ceilings etc. emit little to no particles and can be easily cleaned.
The Metaflex clean room doors also serve this process. Think of airtightness, easy to clean and fire safety.
