Rotating NDCF (= novoflow Dynamic cross-flow)-filter systems are particularly characterised by an outstandingly low energy consumption of           approx. 0.12 - 0.25 KW/1 m² filter area. We offer facilities for rent at different sizes to test your product as well.
Plant sizes available between 1 m² and 500 m² filter area.

Best use:

  • High concentrations
  • High solids load
  • Viscous media
  • Continuous concentration increase of valuable and effective substances
  • GMP standard
  • Ex-protection
  • Surfaces <0.8m
  • Orbital welded pipes
  • Free of dead space
  • Diafiltration (wash-out filtration)
  • Steam sterilisation


Advantages and special properties

  • Energy savings of up to 80 % as compared to conventional cross-flow modules
  • Compact flexible modular build; Simple enlargement or reduction of the plant
  • Double cover layer inspection by combination of centrifugal force (rotation) with shear forces (turbulences by flow impairment)
  • High speeds up to more than 500 rpm at disc diameters of 150 – 375 mm
  • Small standing area
  • Diaphragms can be inspected separately
  • State-of-the-art controls
  • Remote maintenance possible

  • A rotating diaphragm disc stack, installed on a hollow shaft, is located in the filter pressure tank (module)
  • Filtration takes place from outside inwards through the diaphragm discs; the filtration collects inside the diaphragm discs and is discharged through the hollow shaft.
  • In the filter pressure tank, fixed flow impairers can be installed to produce turbulences.
  • Modular build: Easy to enlarge or reduce
  • Automatic backflushing possible
  • CIP-SIP capable


Best use:

  • Separation of particles, colloids, microorganisms, viruses, plasma, macro molecules from contaminated water
