Filter Fan Unit (FFU)
filter fan unit for generating ultra-clean air
The filter and air purification modules are a key factor for success in the construction of cleanrooms and protective zones within a cleanroom facility. clean-tek has invested years of extensive development work in its own Filter Fan Units (FFUs). These ensure a high quality of supply air and reduce the particle concentration in cleanrooms and in individual protective zones.
The air is optionally tempered by a cooler in the upper intake area and can be pre-cleaned by a pre-filter. The intake air is then cleaned by means of a special HEPA filter before it is introduced into the clean room as a low-turbulence displacement flow.
- Generates low-turbulence displacement flow or turbulent mixing ventilation
- Standard and special sizes enable integration into almost all common clean room ceiling systems
- Filter change and fan maintenance possible from above and from the clean room side
- Energy-optimised fans
- Sound-optimised design
- Integrated measuring devices
- High mechanical stability
- Housing: aluminium 1.50 mm (alternatively: galvanised sheet steel 1.50 mm or stainless steel 1.4301 (V2A) 1.50 mm)
- Standard colour: RAL 9010 (other colours on request)
- Sealing: hybrid sealant
- Classic cleanroom ventilation with turbulent mixing ventilation or low-turbulence displacement flow
- Special protection zones with laminar air flow
- Weighing areas
- Production lines
- And much more
- Integration of an air cooler
- Integration of a prefilter
- Air velocity control, e.g. via a sensor
- Air discharge optionally via swirl diffusers, perforated plates or CG distributors
- Filter differential pressure measurement
- Generation of LF areas by lining up several FFUs with CG distributors and corresponding room partitions (PVC curtains or wall systems)
- Special sizes possible (min. 520 mm, max. 1400 mm)
