Grease is one of the biggest problems in kitchen extraction ducts.

With the build-up of grease, the ducts become a field for bacteria and other microorganisms to grow, also increasing the risk of fire and poses a serious hazard to people and facilities.


Grease and odour treatment in office buildings

The cause of the problem lies in the fact that the outdoor outlet for odours is close to or coincides with the air intake of the air conditioning systems, and may even be directly adjacent to other rooms in the same building, thus creating unpleasant situations in other office areas, such as meeting rooms, work stations or offices.

Pollutants such as grease and smoke in kitchen extraction air lead to the build-up of grease in the duct, along with the external emission of grease.


Grease and odour treatment in hotel and catering establishments

Good Indoor Air Quality makes an extraordinary difference in the Hotel and Catering sector, where many customers refuse to return to an establishment if it has an unpleasant smell. Problems with odours are also common in residents’ associations.

Having clean air in a hotel and catering environment is highly profitable.

  • It increases customer consumption.
  • It promotes savings in maintenance costs.
  • It avoids litigation with the administration or residents.

Practical cases of grease and odour treatment

Aire Limpio systems for grease and odour treatment have numerous advantages and benefits for better Indoor Air Quality:

Reduction of grease

Reduced maintenance costs

Only one annual review is required.

Reduction of irritating odours and grease
