FIELD: oil and gas industry.
SUBSTANCE: invention relates to filters for separation of lacker over-spray form crude gas flow containing over-spray particles. Filtering device for separation of lacker over-spray from crude gas flow (104) comprises filtering element (122) to which at least part of crude gas flow (104) is supplied and clean gas chamber (124) to which filtered by means of filtering element (122) crude gas flow (104) is supplied in the form of clean gas flow. To clean gas chamber (124) at least one barrier filter (168) is attributed located downstream of filter element (122) by means of which at least part of crude gas flow (104) is filtered in case of filter breakthrough on at least one filtering element (122).
EFFECT: invention enables to maintain contamination of clean gas at a maximum possible low level in case of filter breakthrough.
