Improve air turbulance in cleanroom by CS Balloon!!
CS Balloon is an air adjustor installed at air supply port to broaden slow
air stream to overall area equally.
To maitain clean environment in cleanroom, enough volume of clean air is needed. Then, to supply enough clean air to cleanroom, some users install the FFU that has capacity to supply large volume of air. But If air velocity from supply port is too high, it may lead to air turbulence which possibly cause undesirable contaminant problem.
For example, when the air from FFU go straight to floor strongly, the dust
nearby may be blown up and float with air stream. If there are any work
pieces at downstream, they probably are contaminated.
Therefore, keeping low velocity of air stream is necessary in cleanroom.
The picuture below shows direction of air stream from FFU no CS balloon
and with CS balloon.
As you see in the video above, with CS-Balloon, air flow is stable that
help keeping cleanliness efficiently.When we remove the CS-Balloon, the
air flow became turbulentthat makes it difficult to keep cleanliness.
We can visualize the air flow by "Mist Stream" and green laser
No CS Balloon
Use CS Balloon
As you see, In case fo NO CS Balloon, the air from supply port is so strong
that remove all mist under FFU. At the same time, there is a lot of mist stays beside the air route,
does not broaden around at all.
On the other hand, when we install CS Balloon at the air supply port, air from the port broaden
weak air stream around neaby area quite equally that is desirable air flow in cleanroom.
Slow down the air velocity and Spread air stream around equally by CS Balloon!!
