Clean Air Products' Series 412 Vertical Laminar Flow Clean Benches have been designed to create a freestanding, ultra-clean mini environment, and are available in a variety of sizes and styles.
Depending on application needs, systems can range from vertical flow benches with open interiors to exhausting clean benches with wet process to recirculating temperature control Class 1 systems.
HEPA or ULPA filters are available to filter particles as small as 0.12 micron with 99.999% efficiency.
Series 412 clean benches feature an upper cabinet module that houses the prefilters, HEPA or ULPA main filters, blower motors and lights. Second is a modular lower support frame that includes the lower work surface module.
This may be as simple as a flat table, or as complex as a bench containing tanks, heated etch baths, gooseneck faucets, drains and any number of other options.
The modular design allows the clean bench to be easily shipped and assembled, and most sizes have been designed to fit through standard doors and hallways.
What differentiates the Series 412 from many other laminar flow clean benches is that it protects against contamination in the event of a gasket leak.
The Series 412 has two seals - one each on the downstream and upstream sides of the HEPA filter.
The space surrounding these two seals is under a negative pressure.
The air in the supply pressure is under a high pressure, and should the gasket leak, it would do so into the negative pressure area and be brought back to the blower.
If the downstream gasket would leak, air would flow from the clean work area back to the negative pressure area.
Larger cleanrooms often require just a few Ocritical cleanû areas making clean benches an ideal solution.
In fact, less than 40% of a typical cleanroom's floor space is dedicated to clean manufacturing and storage.
As a result, it is oftentimes more cost effective to construct a low class cleanroom and supplement it with clean benches than it is to create a higher class cleanroom.
Clean Air Products has been designing and manufacturing cleanroom systems and related products for more than 20 years.
Their products feature rugged metal construction for dependable performance and long life.
They provide custom modification services to create products and systems designed to satisfy specific application requirements.
