Abstract: A front access frame sealing mechanism for filter cassettes comprising at least one pair of posts extending inwardly from opposing sidewalls of a filter cassette housing wherein the posts have a head with a diameter exceeding that of the shaft of the post. At least one camming retainer is mounted adjacent each opposing sidewall about a post wherein each of camming retainer has a cam with a centrally oriented aperture with a diameter greater than the diameter of the post head for mounting about the posts. The cams have a flat portion and a extending handle portion, the flat portion becomes adjacent a sealing channel when in a sealing position. A sealing channel is adjacent each sidewall of the housing with a linear side adjacent front edges of at least one upstream filter cassette and having a channel holding each of the cams.
