Why does dust escape from the collector outlet / emissions exceed limits?

Root causes: 1) Cartridge damaged, cracked or punctured, dust passes through directly; 2) Aged/dislodged/loose seal gaskets cause dust-laden air short-circuiting; 3) Cartridge grade too coarse to capture fine dust; 4) Excessive cleaning pressure penetrates the media surface. Solution: stop and inspect cartridge integrity, replace damaged cartridges and seals, and use high-grade media.
