Most of our competitors use cartridge filters that sit horizontally inside the dust collector. These horizontal dust collection systems experience problems with filter life, gasket leaks, and complicated filter changes. The CMAXX uses vertical cartridges with longer filter life and better pulse cleaning. The anti-ramp lift rails make changing the filters easy. They also prevent filters from ramping, or sliding over each other, while being changed. A filter locking system ensures gasket compression for a solid seal against dust leaks.
