3M™ High-efficiency candle filters, Series 740

A patented radial pleated construction is used in the 3M Cuno high-efficiency filtration system, whereby, in comparison to conventional candle systems, a substantially higher filtration area is developed within a specified space. Thus, each 3M Cuno high-efficiency candle has up to 18 m² filtration area.


  • high contamination absorption capacity (up to 11 kg)
  • 100 % utilisation of the filtration area
  • high filtration area using radial pleated technology
    (up to 18 m²)
  • long service life of the filter
  • easy and clean filter replacement
  • high through-flow rates
  • removes oversize particles, fibres and gel particles
  • robust structure of the filter candle, thus no deformation
  • ensures controlled separation
  • space-saving
  • O-rings form a safety seal that prevents any bypassing
