DEVICE FOR AIR FILTRATION, CONTAINING SUBSECTIONS, BETWEEN WHICH THERE IS NO FLUID COMMUNICATION Russian patent published in 2016 - IPC A62B7/10 

FIELD: ventilation.

SUBSTANCE: device 10 for air filtration, comprising a housing 12, comprising a plurality of subsections 32, 34 and 36, at that each subsection comprises a filter element 26, 28 and 30. The inlet opening 18 is located in the first portion of the housing 12, and the air distribution system located upstream is in fluid communication with the inlet opening 18 and each of the subsections 32, 34 and 36. The air distribution system located downstream is in fluid communication with each of the subsections 32, 34 and 36, and the outlet opening 20 is in fluid communication with the air distribution system located downstream. The subsections are arranged so that all the subsections 32, 34 and 36 are not in fluid communication with each other. By using such a construction of the device for air filtration, the air flow can pass through the device more effectively to extend the overall life of the product with simultaneous minimizing the flow resistance of the entire filter.

EFFECT: control of air flow through the filter materials, which extends the life of the filter material.
