diffusers are required for these applications.
No terminals required for ISO Class 6 and above
Noise level
Lower noise - due to high quality 3 phase efficient
industrial motors - located away from the cleanroom
ceiling.
Higher noise level especially overtime
loading
Filter Replacement
Less filter replacement frequency
Filters replaced externally - less down time and total
protection of cleanroom processes and equipment
More frequent filter replacement in
comparison to DFS
Meeting requirements
filtration systems meet or exceed CDC for positive
and negative pressure rooms at efficiency higher than
one provided by HEPA supply:99.9999% @0.007µm
Meets CDC engineering specifications
for filtration efficiency (99.97% at 0.3
µm)
