- Contaminated air is taken in via a disposable pre-filter at the top of the cleanroom.
- After the larger particles have been absorbed by the pre-filter, the air passes through the HEPA H14 end-filter, creating a stream of clean laminar air within the working zone.
- The HEPA-filtered air goes downwards in a unidirectional flow. The side curtains terminate at a specific height to allow the air to leave the SoftCube. The positive pressure within the working zone prevents contaminants from entering.
