The Filter Blaster can now be used on bag and sock filters used in concrete silos, dust collectors and any other applications where hanging, soft-sided filters are used. The Filter Blaster Cage for use with our 3″ Rotor, allows the operator to clean the bag filters by simply feeding the Filter Blaster into the filter and while the rotors is spinning and applying low air pressure to clean, the cage ensures the filter never comes in contact with the rotor eliminating any chance of damaging the filter during cleaning.For use with the 3″ rotor only.
