Laundry Dryer Extraction Ducts, like all ventilation systems, need periodic inspection and cleaning to remove all residues ( hair, textile fibers, powders, etc. ) that are deposited inside
and which can decrease their efficiency and constitute a fire hazard due to their high
flammability.

It is therefore necessary to organize a periodic inspection in order to check the state of
extraction  system and then to plan the most suitable intervention.
