White room description
Local locations in general constructed of sandwich panels are completely sealed with a calibrated air outlet which allows an overpressure of the room (from the sanitized to the other less sensitive premises to avoid the re-entry of dust).
Plinths, moldings and corners are generally rounded to facilitate cleaning and to avoid any deposit of dust, all glazed parts and doors are flush with the partitions for the same reasons.
These dust-free zones are classified into different ISO classes 1 to 9 according to the filtration fineness of the air conditioning and the number of dust particles admitted by M³.
Air conditioning can be very extensive depending on the type of activity (strict control of temperature, air change and particle size and amount of dust.
The floor of clean or gray rooms is usually covered with epoxy resin or with PVC bonded / welded.
Uses range from electronic assembly (gray rooms) to pharmaceutical production areas and operating rooms (clean or sterile rooms).
