Low dust emission values

Small footprint

High filtration efficiency

HOPPERTOP is a compact, cylindrically shaped venting filter designed for installation on weigh hoppers in concrete batching plants as well as on small process equipment where installation space is limited.

The unit is available in multiple configurations to adapt to different system layouts and operating conditions, including versions with integrated fan operation and ATEX-compliant solutions for potentially explosive atmospheres.

Function

HOPPERTOP is designed for intermittently filled, mechanically loaded hoppers and small process installations requiring efficient dust control.

Dust separated from the air stream by a single WAM cartridge filter element is returned directly into the hopper. An integrated automatic reverse air jet cleaning system ensures effective removal of dust from the filter media, maintaining consistent performance.

Depending on the configuration, HOPPERTOP can operate either as a standard venting filter connected to a central suction system or as an active solution with integrated fan.
