Maintenance and cleaning of filters in extraction systems

A frequent question in the gastronomy and food industry is how often the filters of the hoods or filtration equipment have to be cleaned. It is also questioned whether it is very important to maintain good hygiene in these parts of the extraction system. The answer obviously depends to a large extent on the workload, the type of cooking and the products being cooked. However, regular cleaning of the filters is crucial for the proper functioning of the extraction system.

Why is filter cleaning important?

Operational Efficiency: Hood filters become clogged and filled with grease, which causes them to stop working properly. When the filters cannot retain the grease, it travels into the ducts and reaches the fan. This can lead to imbalances in the impeller, noises in the ventilation box and eventually to deterioration of the equipment, including the motor and fan.

Safety: Grease build-up in ductwork can become a serious fire hazard. Keeping filters clean is an essential preventive measure.

System Durability: Proper maintenance prevents grease and dirt from getting into places they shouldn’t, prolonging the life of the extraction system and avoiding costly repairs or replacements.

Tips for cleaning metal filters:

Soaking: Soak filters in hot water with a suitable degreaser for 30 minutes.

Scrubbing: Use a soft brush to remove debris without damaging the filter.

Rinse and dry: Rinse with hot water and allow to dry completely before reinstalling.

By taking care of the maintenance of the filters in your extraction systems, you will not only improve the quality of the air in your kitchen, but also prolong the life of the system.
