Ventilation systemswith clean room character

for the protection of sensitive hygiene areas

The VDI 6022 “Raumlufttechnik, Raumluftqualität – Hygieneanforderungen an raumlufttechnische Anlagen und Geräte (VDI-Lüftungsregeln)” apply to all air-handling systems. Theses have to be planned, carried out, operated and maintained so that they ensure a hygienic flawless quality of the supply air and take care of room air, which presents no health risks. This also includes the ventilation systems.

VENTAFLEX® air ducts match and are certified for hygiene applications according to VDI 6022.

The VENTAFLEX® air ducts have clean room character due to their material characteristics. The smooth surfaces avoid adhesion, are easier to clean and minimize the friction losses for a hygienic air flow.


Applications with special requirements to a clean air supply are made for example by:

  • health institutions like rehabilitation clinics, nursing homes, hospitals
  • educational institutions like schools, swimming pools, sports- and multi-purpose facilities
  • scientific institutions like laboratories and the chemical industry
  • industrial branches like food- and beverage companies as well as
  • meeting points for people such as museums and exhibition halls
