摘要：
FIELD: instrumentation veterinary science.SUBSTANCE: group of inventions relates to air filtration systems used in places of livestock management. Filtration element made to filter virus of swine reproductive and respiratory syndrome – PRRSV from air flow in building for livestock management comprises rectangular frame, filter filler package extending through frame in configuration without zigzag arrangement of filtering panels with depth less than 8 inches, so that in combination with filtering element it has depth less than 10 inches in direction perpendicular to plane defined by rectangular frame. Filter filler package has MERV rating of at least 14 and efficiency of filtration sufficient for preventing transmission of PRRSV and capacity of air flow is more than 200 cfm at resistance of 0.2 inch of water column per square foot of filtering element across air flow. Filtering element in second version comprises support frame, filter filler package containing filter filler extending through support frame and having depth greater than approximately 3 inches, filter filler with MERV rating of at least 14 and volumetric air flow capacity, which exceeds 500 cfm/min of external filter loop at resistance of 0.2 inch of water column. Filter filler package has configuration without zigzag arrangement of filtering panels. Filtering system intended for air filtration for animals contains filter casing installed in building of generating air flow through filter casing, filtration element tightly installed on housing, which includes frame, filter filler package supported by frame in configuration without zigzag arrangement of filtering panels with depth of more than 2 inches and less than approximately 11 inches, so that in combination with filtering element it has depth of approximately 12 inches or less in direction perpendicular to plane defined by rectangular frame, and having MERV rating of at least 14. Wherein filter filler package has MERV rating if at least 15, efficien
