Why does MBA use cartridge filters instead of envelope or tube style filters?
MBA can manufacture dust collectors with every type of filtration, but it is rare when a cabinet is sold without cartridge filter dust collection. Dust collector filter area is one of the most important factors when choosing a blast cabinet. Dust collectors with greater filter area can operate longer without service. It is technically feasible, but not practical, to build different collectors of the same filter area. Envelope filters yield about three times the filter area per square foot of floor space than tubular collectors. Cartridge collectors yield double the filter area over envelope filters (six times the area over tubular filters). Dust collectors with greater filter area are able to disperse the volume of air traveling through the collector more efficiently. The efficiency is commonly measured by the air to cloth ratio (the ratio of exhaust blower volume to filter area). Ideally, the air to cloth ratio in a dust collector should be 3:1 or less. Practically, air to cloth ratio
