HOPPERTOP is suitable for discontinuously, mechanically filled hoppers.Dust collected from the air flow by a single WAM cartridge filter element drops back into the hopper after the reverse action of a compressed air pulse air jet generated by an integrated automatic cleaning system has removed the dust particles from the media. A hinged top cover protects the filter from weathering.
