Technical Specs


HOPPERTOP is a compact, cylindrically shaped venting filter for installation on weigh hoppers in concrete batching plants and, in general, where limited space is an issue.
Weigh Hopper Venting Filters


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.
