Fan Filter Units
Cleanroom applications need the latest air conditioning technology applicable to the local facilities and utilitie.
Why should FFUs be used in cleanrooms?
Benefits which count ...
... Redundancy
With hundreds, or thousands of individual FFU?s in a facility, the loss of one or more units does not jeopardize the integrity of the room.
... Flexibility
As the needs or uses change in a facility, the units can be exchanged with lay-in lights or blank panels.
For facilities with lower classification, upgrades can be obtained by simply adding additional FFU?s.
When a computer controlled management system is installed, units or clusters of units can be remote controlled to operational needs.
... More cost effective
Use motors with the lowest power consumption available.
With complete controllability of each and every FFU (via control and monitoring software) use just as much of power as necessary for your process.
... Negative plenum
The negative plenum design draws recirculation air from the plenum itself. If there are any leaks, they migrate to the negative plenum and NOT the cleanroom.
... Functionality
FFUs are fully functional as stand alone units.
