Lynx Kitchen at Oslo Airport: Two Years Running, Ducts Still Completely Clean
Two years after installation at Oslo Airport Gardermoen, documentation shows that the ventilation ducts from the commercial kitchen are still completely clean. This is a result that breaks with all established industry practice — and has significant implications for how commercial kitchens can and should be operated going forward.
Avinor installed the Lynx Kitchen system in 2024 as part of their commitment to sustainability, safety, and operational optimisation. Two years later, in April 2026, Norsk Ventilasjon AS carried out a thorough inspection of the ventilation system. The conclusion was unambiguous: the ducts are still clean. No cleaning is required.
For an industry that has accepted the need to clean kitchen ventilation regularly — typically every 6–12 months — this is a remarkable result.
"We have never seen anything like it. After two years of operation, we would have expected significant deposits of grease and particles in the duct system. Instead, we find clean surfaces. It is simply a different reality from what we are used to." — Norsk Ventilasjon AS, inspection report April 2026
Conventional commercial kitchens struggle with a combination of challenges that Lynx Kitchen eliminates:
- Grease deposits in ducts requiring frequent and costly cleaning
- Fire risk associated with grease build-up
- Operational downtime during cleaning and maintenance
- Energy loss because extraction systems must run at maximum capacity to compensate for blocked ducts
- Working environment challenges relating to odours, heat and particles
When ducts remain clean over time, several of these problems disappear simultaneously. This is not a marginal improvement — it is a structural change in how a commercial kitchen can be operated.
For Avinor, this is about more than clean air. It is about predictable operations, reduced risk, and lower total cost of ownership over time. For Lynx Kitchen, the Gardermoen installation is confirmation that the technology delivers on its promise — even under some of the most demanding operating conditions found in Norway.
