Filter-Fan-Unit (FFU)

Filter-fan unit for clean air generation

Especially the filter and air purification modules represent a very central success factor in the construction of cleanrooms and protection zones within a cleanroom facility. clean-tek invested years of development work in their own filter fan units (FFUs). They produce a high quality of supply air and reduce the particle concentration in cleanrooms or individual protection zones within a cleanroom facility. In the upper intake area, the air is optionally cooled by an attached cooler and optionally also pre-cleaned by a pre-filter. The intake air is then cleaned by a special HEPA filter and introduced into the clean room as a low-turbulence displacement flow.

  • Generates low-turbulence displacement flow or turbulent mixed ventilation
  • Standard sizes and special dimensions allow integration into almost all common cleanroom ceiling systems
  • Filter change and maintenance of the fan possible from the cleanroom side and from above
  • Energetically optimised fans
  • Sound-optimised design
  • Integrated measuring devices
  • High mechanical stability

  • Housing: aluminium 1.50 mm (alternative: sheet steel, galvanised 1.50 mm or stainless steel 1.4301 (V2A) 1.50 mm)
  • Colour standard: RAL 9010 (other colours on request)
  • Sealing: Hybrid sealan

  • Classic clean room ventilation with turbulent mixed ventilation or low-turbulence displacement air flow
  • Special protection zones with laminar air flow
  • Weighing areas
  • Production lines
  • and much more.

  • Integration of an air cooler
  • Integration of a pre-filter
  • Air speed control, e.g. via a sensor
  • Air outlet optionally via swirl diffusers, perforated plates or CG distributors
  • Filter differential pressure measurement
  • Generation of LF areas by stringing together several FFUs with CG distributors and corresponding room partitions (PVC curtains or wall systems)
  • Special sizes possible (min. 520 mm, max. 1400 mm)
