HOPPERTOP is a small cylindrical venting filter specifically for installation on weigh hoppers in concrete batching plants. 
 

HOPPERTOP is a compact venting filter for mechanically filled hoppers. Dust which is separated from the air flow by a single WAM® cartridge filter element drops back into the hopper after an integrated automatic reverse air jet cleaning system inside the weather protection cover has removed the dust particles from the filter elements.
