Filter assembly

Abstract

Provided is a filter assembly that resolves a high differential pressure between the front and rear ends of a filter and limitations in dust and paint collection performance due to an inefficient internal structure of the filter. The filter assembly includes a housing, a paper core filter received in the housing and folded in a zigzag shape, supports coupled to the paper core filter to maintain the shape of the paper core filter and support the paper core filter, and the supports includes a first support configured such that a plurality of plate members is coupled, and coupled to first regions configured such that air before filtration is introduced thereinto in the folded paper core filter, and second supports configured such that a plurality of plate members is coupled, and coupled to second regions configured such that air after filtration passes therethrough in the folded paper core filter.
