Zusammenfassung:The present invention relates to an air filter apparatus for filtration of a compressed air which filters the compressed air of an air compressor. More specifically, according to the present invention, a rotational force generating means (50) for generating a rotational force of the compressed air is installed in a cylindrical filter (20) installed inside a filter housing (10), so that a rotational centrifugal force is generated in the compressed air supplied to the inside of the filter. As a result, the compressed air does not pass through only one end face of a filter paper (21) of the cylindrical filter as in a prior art, but is dispersed and passed as a whole, thereby preventing a differential pressure. In addition, as a filtration area is increased, filtration efficiency and filter efficiency are greatly improved, and thus a service life of the filter is longer, thereby reducing an operating cost. 본 발명은 공기압축기(콤프레셔)의 압축 공기를 여과하는 압축 공기 여과용 에어 필터장치에 관한 것으로, 좀더 상세하게는 필터 하우징(10) 내부에 설치되는 원통형 필터(20)에 압축 공기의 회전력을 발생시키는 회전력 발생수단(50)을 설치하여 필터 내부로 공급되는 압축 공기에 회전 원심력을 발생시켜 주므로 압축 공기가 종래와 같이 원통형 필터의 여과지(21)를 한쪽 단면만 통과하는 것이 아니라 전체적으로 분산되어 통과되도록 하면서 차압을 방지하고, 여과 면적이 넓어져 여과 효율 및 필터 효율을 크게 향상시킴은 물론 이로 인해 필터의 사용 수명을 좀더 길게 사용할 수 있어 운영 비용을 절감하게 되도록 하는데 그 특징이 있다.
