Hopper venting filter for efficient dust filtration

Achieve superior dust control and efficient material handling with a compact venting filter designed for safe and clean operations, ensuring your production environment meets stringent emission standards while maintaining optimal performance.

Filters and Vents Dust from Production Lines

The HOPPERJET from WAMGROUP is a compact hopper venting filter designed to optimize dust control in various industrial operations. It features a polygonal design with a small footprint, ideal for installation on storage and weigh hoppers. Using a single POLYPLEAT or bag-type filter element, it effectively separates dust from air via an integrated automatic reverse air jet cleaning system. This maintains a continuous and efficient filtration process, reducing emissions significantly. The HOPPERJET is suitable for applications in building materials, chemicals, food, plastics, and heavy industries, producing end-products like precast concrete panels, pharmaceutical tablets, and plastic granules. It operates with air volumes ranging from 30 to 200 m³/h, supported by a compressed air pulse-jet cleaning system. Constructed with a stainless-steel casing, the equipment can be adapted for explosive environments under the ATEX directive. Easy installation and tool-free filter element replacement make the HOPPERJET user-friendly and efficient for large-scale dust management and air quality control in industrial settings.

Benefits

  • Minimizes dust emissions with high filtration efficiency.
  • Compact design saves space in crowded production facilities.
  • Corrosion-resistant materials ensure long-term durability.
  • Quick, tool-free filter replacement reduces maintenance time.
  • ATEX-certified options enhance safety in explosive environments.
