AIR FILTRATION SYSTEM IN FACILITIES FOR STABLING ANIMALS USING PANEL AIR FILTER WITH ZIGZAG PANEL ARRANGEMENT Russian patent published in 2015 - IPC B01D46/00 

FIELD: agriculture.

SUBSTANCE: group of inventions relates to air filtration systems used in buildings for stabling animals. The filter system comprises a housing having a rectangular inlet opening provided in one of its walls, surrounded by a rectangular sealing surface, and an outlet opening formed in its another wall, a door pivotally mounted relative to the housing between the open and closed positions and having a through hole and a rectangular mounting surface surrounding it, and when the door is in the closed position, the through hole is aligned with the rectangular inlet opening. The filter system comprises a hinge strap connecting the door to the housing on which the door rotates about the hinge strap between the open and closed positions, the rectangular panel filter mounted on a rectangular mounting surface of the door, at least one panel air filter with a zigzag arrangement of the panels, located in a rectangular inlet opening, and having a rectangular peripheral flange with a rectangular sealing surface, a latch connected between the door and the housing designed for retaining at least one rectangular panel preliminary filter located upstream from at least one panel air filter with a zigzag arrangement of the panels, and a sealant located between the rectangular peripheral flange of at least one panel air filter with the zigzag arrangement of panels and the rectangular sealing surface. And the panel air filter with the zigzag arrangement of the panels has a plurality of sections of the filter filler, protruding from the peripheral flange and inwards the housing.

EFFECT: increase of the efficiency of air purification from pathogenic agents and reduction of the rate of transmitting of pathogenic agents over the air.
