Abstract: This invention is related with the internal cleaning system (Telescopic Cleaning System (10)) of centralized extraction and filtration units (1) of industrial exhaust gases aiming to reduce overall energy consumption of such system by; avoiding the usage of compressed air being replaced with available exhaust air of the system, accelerated and applied thoroughly all surfaces of the cassette filters (2) by the help of Telescopic Cleaning System (10) and delivering efficiently cleaned filters, generating less resistance over the filter unit (1) versus comparable existing designs by the help of such efficiently cleaned filters, leading to less energy consumption on exhaust air fan.
