If within granulation home is positive e.g 20 Pa and during the lock is 10 Pa the powder from granulation area will enter from the airlock and if during the corridor is 8 Pa then this powder will go from airlock to corridor and will contaminate other areas.
Interlocking Doors: Following the mandatory preparations and checks are completed In the airlock, the interior door is often opened. This allows personnel to enter the cleanroom when ensuring which the outer door stays shut, sustaining the stress and cleanliness in the cleanroom.
