Plate filter unit Version 12/9

panelairhigh-throughput

Product description
The Fan Filter Unit is a classic solution for cleanroom applications. Air is drawn in by a powerful fan and discharged after a multi-stage filtration process. The unit can also generate a stable slight overpressure for cleanroom environments.

Functional description
The FFU operates in recirculation mode. Air from the intake area (1) is drawn in by the fan (5). The prefilter (3) cleans the intake air. The final HEPA/ULPA filter (11) filters the air to cleanroom standards. The filter guard (6) prevents damage to the filter media. A perforated plate (14) is used to generate a displacement flow with low turbulence.
