Expert in Air Purification

  • UV suppresses the formation of mold within the airconditioning system.
  • Reduction of viruses and bacteria, preventing them from multiplying.
  • Disinfects the air as it passes through the air conditioning system.
  • Good where air circulates constantly

Why UV

UV light offers a solution to the problems posed by contaminated water. Home UV systems—integrated into the plumbing—and portable UV filters—for on the go—allow people to live where they want and travel where they wish, always ensuring access to clean, safe water.

Background Knowledge

  • Photolytic effect on DNA: micro-organisms such as bacteria, moulds, yeasts and viruses cannot replicate.
  • Purification effect is obtained at wavelengths below 320 nm, with maximum effectiveness achieved at 260 nm.
  • OSRAM HNS germicidal lamps emit light at 254nm, very close to the maximum effectivness and are ozone-free



  • Low-pressure Hg discharge lamp
  • RoHS compliant
  • With UV-C transparent long-life coating
  • Soft glass tube
  • Single UV-C peak @ 254nm
  • Not generating ozone
  • High efficiency (30% UV-C output)
