Dry filtration system

A filtrations system for a mobile vehicle operating a grinder used for removal of markings or creating rumble strips, said filtration system comprising:

• a debris bin secured to said mobile vehicle;
• a rotary lobe vacuum blower fluidly coupled to said debris bin, said vacuum blower having a suction juxtapositioned to the grinder for drawing debris into said debris bin;
• a filter cyclone fluidly coupled to said debris bin, said filter cyclone formed from a cylindrical tank having a plurality of spaced apart filter bags constructed and arranged to allow a cyclonic flow of air therebetween before passing through said filter bags for separating particles from the debris, said cylindrical tank having a collection box positioned beneath said filter bags;
• a slide valve for reversing a high volume of cleaned air through said filter bags;
• a vibrator diaphragm positioned along an outlet of said spaced apart filter bags, said vibrator displacing said diaphragm wherein said diaphragm provides alternating positive pressure and negative pressures within said filter bags for dislodging particles adhering to said filter bags;
• a polishing tank partially filled with water coupled to an exhaust of said filter cyclone, said polishing tank constructed and arranged to direct the exhaust of the filter cyclone through the water for removal of airborne particles and to provide sound suppression.
