Cleanroom – Air ducting in double walls

In our CleanCell cleanroom systems, the filtered and air-conditioned room air is fed back to the filters in an energy-efficient recirculation process within double cleanroom walls and then reintroduced. Only part of the air is then fed in as fresh air to maintain the oxygen content.

“>This is also possible within fully glazed walls. You can see this clearly in the flow visualization. What happens next?

Filter Fan Units (FFU) with integrated high-performance HEPA filters are installed in the cleanroom ceiling, which draw in the air, filter it and blow it into the cleanroom at the desired pressure. Cleanroom blow. The low-particle air flow, also known as laminar flow, displaces the particle-laden air in the Cleanroom and directs it back into the recirculating air walls through outflow openings on the floor.

However, simpler systems such as cleanroom tents or cleanrooms can also be operated without an air recirculation system. In these cases, 100% of the clean air is discharged via discharge grilles, process openings or the floor gap.
