Structurally improved filter housing and mounting apparatus

Abstract From the Canadian patent

A self-cleaning air filtration system has a vertically oriented housing internally divided by a horizontal centerplate into an upper clean air discharge chamber, in which a filter backflushing system is disposed and a lower contaminant chamber. Interconnected partition panels are positioned within the contaminant chamber and are intersecured between the centerplate and the housing sidewall section surrounding the contaminant chamber to thereby structurally brace the centerplate and sidewall section, and divide the contaminant chamber into a series of vertically extending contaminant subchambers having open lower ends communicating with a hopper section depending from the housing.
