KOKEN opening clean bench KOACH
When I let the high-performance same flow that I cleared through a filter face and hit it, surprising space was born. (patent pending)
I form the cleanliness space without surrounding a rotation. I can install the cleanliness space in the necessary place easily and can move more.
It is the heaven-sent child in the times when open clean bench "KOACH" which can form the clean space of the constant range in the opening space can balance workability and energy saving without needing construction.

The high-performance same flow
Balloon air current to form an open clean zone
Balloon air current to form an open clean zone
A balloon air current includes the important element forming an open clean zone. KOKEN was stable in its wind velocity, direction of the wind, and there was not unevenness and succeeded in creating the balloon air currents that even the slight wind velocity and the air volume that there was few it were hard to scatter more.
The clean zonal formation was enabled even if I did not surround a rotation by adopting this high-performance same flow.

The formation method of the cleanliness space
The formation method of the cleanliness space
The general clean bench sends air with the air which I filtered with air filter and prevents an inflow of the fresh air by keeping the surrounded work space in a positive pressure state, and it is in structure to maintain the high cleanliness degree.
While open clean bench "KOACH" is structure having high workability without the wall, I find the high cleanliness degree that is equal to a clean bench for it. It is the high-performance same flow and two air currents technology called the facing type air current that enabled it.
The cleared high-performance same flow gushes out of push food of open clean bench "KOACH". However, even if it is the high-performance same flow, I induce neighboring air as I burst into laughter if a rotation is not surrounded and leave the aspect, and the cleanliness domain gradually gets narrow. (figure 1)
It is opening clean bench "KOACH" that solved this problem in letting a cleared high-performance equality style to gush out of two push food which let you face collide (facing type air current). Because inducement of neighboring air is controlled by a facing type air current, the drop of the cleanliness degree in the zone is hardly seen even in a position away from the balloon plane. (figure 2)
While the high-performance same flow is the slight wind velocity, I can get a long air current outreach. The facing type air current that open clean bench "KOACH" creates is formed simply because I let this high-performance same flow collide and can form the cleanliness space of the wide range though there is not a wall.

Air current simulation of KOKEN opening clean bench "KOACH"
I performed the CFD analysis by our parameter and simulated air current distribution of "KOACH".
I show the result in the chart below. In fast order of the speed of the air current, it is red → Yellow → Green → I am shown with blue.

Merit of the open clean bench which "I do not surround"
It brought a big merit in workability that it was not necessary to surround a rotation by open clean technology.
I compared the workability in open clean bench "KOACH" with the workability in the conventional clean bench which I surrounded.

Workability in "KOACH"
In comparison with a conventional general clean bench,
・There is not an occlude feeling for structure without a wall
・I can secure view widely
・Because a meeting is performed a bulletin of, in the work middle
The putting in and out of half-finished goods is possible
Performance of open clean bench "KOACH"
I show below the performance about the clean degree of open clean bench "KOACH".
I placed a work table, a mannequin and an air current obstacle between push food of "KOACH" and performed the clean degree measurement.

Ecology & economy
The open clean technology is the technique that I can contribute to in not only high performance and the good workability but also the energy saving. Not only the formation technology of the clean space is high, but also open clean bench "KOACH" can lose the extra power consumption that I spent on existing clean room maintenance by the introduction and is the device which can thereby contribute to greenhouse gas (CO2) discharge reduction.
Challenge to eco-innovation
Problems about the environment including global warming and the ozone depletion become the important issue, and the interest in issue of global environment of people increases. The influence that a company activity gives in environment is big, and the active approach to an environmental problem solution is hoped for.
A medium-term aim to reduce a greenhouse gas discharge 25% compared to 1990 in the new cabinet by 2020 in 2009 was expressed. Only it suppresses the energy consumption if I can make a clean zone the minimum range and can contribute to greenhouse gas reduction.
