Metal separator for pneumatic conveyor pipes


The GF 4000 metal separator is an advanced solution designed for the detection and separation of both magnetic and non-magnetic metal impurities within bulk materials such as granulates, powders, and flour. Engineered with cutting-edge technology, this metal separator offers exceptional performance and reliability, making it an ideal choice for quality control in industries like food processing, chemicals, and pharmaceuticals.


Key Features Metal Separator:

  • Metal separator detection and separation of magnetic and non-magnetic metal particles.
  • Metal separator designed for high flow rates.
  • Easy integration into existing pipeline systems with metal separator.
  • Metal separator available in versions up to atex zone 20 for hazardous environments.
  • Auto-learn function for ease of operation include in metal separator.
  • Metal separator utilizes the latest microprocessor technology.
  • Metal separator components designed to meet stringent hygiene standards.
  • Suitable for horizontal, vertical, and inclined vacuum and pressure pipes.
  • Modular design of metal separator allows adaptation to different conveying methods.
  • Quick flap system of metal separator is for rapid removal of metal contaminants without interrupting the production process.
  • Excellent metal detection with maximum resistance to interference using metal separator.
  • Metal separator highly reliable both mechanically and operationally.



Small metal particles in the plastic melting process often result in costly breakdowns of injection moulders, extruders and blow moulders. The quantity of such metal contaminants increases throughout the processing of regranulates and grinding stock. As a result, clogged nozzles, filters and hot channel systems can lead to production downtime and delayed delivery.

The metal separator GF is used in vacuum and pressure pipelines to protect injection moulders and converting machines.

It detects all magnetic and non-magnetic metal contaminants (steel, stainless steel, aluminium, etc.) – even when they are enclosed in the product. Metal contaminants are ejected via the “Quick-Flap” separation unit.

Applications of Metal Separator:

  • Metal separator for Inline inspection between silo and filling system (e.g., in mill plants).
  • Metal separator for Incoming goods inspection prior to filling silos.



Control Units of the Metal Separator:

  • Two control units available in metal separator: GENIUS+ and SENSITY.
  • Common features of metal separator include highest sensitivity to all metals (2-channel technology), digital signal processing, quartz-stable search frequency, state-of-the-art microprocessor technology, self-monitoring, auto-balancing, temperature compensation, product compensation with auto-learn function, multi-product memory, password protection/access protection, and metal separator special EMC combi-filter for suppressing external interference



Installation of the Metal Separator:

  • Metal Separator Can be integrated into horizontal, vertical, and inclined vacuum and pressure pipes.
  • Retrospective installation of metal separator in existing pipeline systems is straightforward using quick connectors or air-tight flanges.
  • Metal Separator Suitable for standard nominal widths up to 150 mm.
