Longer shelf life with clean air
A clean production environment is guaranteed
by a cleverly devised system for routing the air
flow, an arrangement based on high - quality
submicron particulate air filters that trap the
smallest particles and micro - organisms.
These systems use special HEPA filters (high
efficiency particulate air filters) that filter out
suspended particles only 0.5 µm in diameter. By
way of comparison, the average bacterium cell
has a size of approximately two micrometers.
Not all clean rooms are the same, however.
Clean rooms are defined by ISO clean room
classes. The Standard ISO 14644-1 defines how
many particles of what size are allowed in one
m³ of air ISO Class.
