| Vertical Flow Clean Bench |
|
|
The Series 412 vertical laminar flow clean
bench is specifically designed to create a
freestanding ultra-clean mini-environment. The Series 412 Clean Bench, or mini-environments, are available
in a variety of sizes and styles engineered to
provide excellent solutions for many air filtration
applications. The Series 412 Clean Bench may vary from vertical
flow benches with open interiors to exhausting
clean benches with wet process, to recirculating
temperature control Class 1 systems.
A Clean bench can be used in conjunction with
cleanrooms to create clean zones. They can also
be used in lieu of or supplemental to a cleanroom.
Often times in larger cleanrooms, there are a few
"critical clean" areas. It is sometimes more costeffective
to build a lower class cleanroom and
supplement it with clean benches, than it is to
create a higher class cleanroom. This is especially
true when over 60% of a typical cleanroom floor
space is area where clean manufacturing or storage
does not occur.
