Hopper venting filter

‹‹ ››

Venting filter for balancing volumes in hoppers, feeders…

A clean process without dust emission is a major advantage for ATEX installations

Compact venting filter for mechanically filled hoppers. Dust which is separated from the air flow by a 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.

Main advantages

  • Reintroduction of fines in the process ; no loss of material
  • Minimum maintenance
  • High Efficiency
  • Minimum space requirement
  • Easy installation even in existing facilities
