Magnetic filter

industrialstainless steelflange

Overview
A magnetic trap for pneumatic conveying systems captures and removes ferrous metal contaminants from powders, granules and bulk solids to protect product purity and downstream equipment. Typical assemblies include a stainless steel housing guiding the material flow, magnetic elements (bars, plates or tubes) and accessible cleaning features that enable safe separation without interrupting the process.

Key features

• Stainless steel construction.
• Design diameters available from 6" to 12" (round section).
• Overall height typically 180–200 mm depending on model.
• Flanged top and bottom connections for inline installation.
• Rare-earth permanent magnets with stainless steel coating; front-detachable design.
• Manual magnet extraction using side rails; magnets replaceable.
• Special manufacturing options for specific applications.
• Optional accessories: gate-opening sensor for installation monitoring.

Types of magnetic traps

• Bar traps: magnetic bars installed inside a housing to attract and retain small metal particles; designed for easy cleaning.
• Plate traps: flat magnetic plates positioned in the material path to capture larger metal contaminants; suitable for high-volume flows.
• Tube traps: magnetic tubes inserted into the flow path for pipe configurations.
• Drum traps: rotating drum type for continuous separation in bulk handling applications.
• Belt traps: conveyor belts equipped with magnets to retain metal particles during transport.

Industrial sectors using magnetic traps
Used in food, pharmaceutical, chemical, plastics, mining, recycling, construction (cement and sand), pulp & paper and coatings industries to remove ferrous contaminants and protect process equipment.
