FILTRATION SYSTEMS FOR COMMERCIAL KITCHENS-EX/FNS/054

The quality of the air in professional kitch- ens is a very important parameter that most of the insiders underestimate.Managing it correctly affects security of the workers (cooks, help cooks, waiters, etc.) but also the quality of the room, because there is nothing worse for a customer than coming out of the restaurant with soaked clothes from unpleasant odors of food.At the same time, healthy and suitable working conditions must be guaranteed for all workers.An adequate system of aspiration and treat- ment of fumes, finally, also benefits from neighborly relations.The extractor hood or filtering hood is in- tended to provide acomfortable environ- ment for the operation of the kitchen staff and not only. The non-op- timal functioning of an air treatment system filtering or suction hood, filtering ceiling and deodorizing unit) leads to higher main- tenance costs of the premises and poor hygienic and safety conditions, both for the customers and for the operators. It is there- fore essential to gear up to be up to stand- ard. Each cooking equipment emits fumes or vapors produced by combustion during food preparation.The function of the hoods is that of capturing and expelling such fumes, in addition to re- ducing in part the contribution of heat from the equipment.The air treatment process has two critical aspects: on the one hand, systems that re- store the air in the kitchen area, with theconsequent winter and summer air-condition- ing costs, are needed; on the other hand, there is the risk of introduc- ing into the environ- ment air that contains combustion residues, fumes and odors.

1. Electrostatic or electronic filters, FEL SYSTEM
2. Ozone filters, FX SYSTEM
3. Negative ion filters, FI SYSTEM
4. Plasma, a cylindrical cartridge system that emits ozone and negative It works well only if there is not a high concentration of humidity in the filtered air.
5. UV lamps, a system made up of neon tubes that generate ultraviolet rays that produce ozo- They have a big limit, they last only about 4000 hours.

There are essentially 3 types:

• • traditional hoods with suction
  • compensating hoods with labyrinth filters and filtering
  • suction ceilings (they also function as fil- tration).
