HF Series Drawer Magnets for Separation in Enclosed Flow Lines with free flowing material

Versatile Drawer Magnets Fit Many Applications

Bunting® HF Series Drawer Magnets are equipped with powerful magnetic cartridges to handle a wide range of separation tasks in mechanical or gravity flow applications. They can be ordered with one or more cartridge trays. The more trays, the more contact with the product stream. A minimum of two staggered trays is recommended, where space will allow, so that material can flow in a zig-zag pattern from one cartridge tray to the next for exceptionally thorough cleaning. HF Series Drawers are available in utility, powder, food, and sanitary construction grades with three cleaning options and stainless steel housings. Custom transitions to match your spouting are available.

Self-Cleaning Options Save Labor and Downtime

In the standard configuration, ferrous debris is removed from the cartridges by sliding the trays out of the housing and wiping them off by hand. Self-Cleaning HF Drawer Magnets are designed to fully extend the magnetic cartridges outside the housing. As these tube assemblies travel outside the housing, grommets wipe the tubes clean all the way to their nonmagnetic tapered ends. This ensures that each cartridge is fully wiped and prevents captured tramp iron from reentering the housings.

Self-cleaning models are available in both manual and fully automatic pneumatic versions and in tube-over-tube configurations. Pneumatic units can be installed in hard-to-reach locations because they operate at the touch of a remote switch or by a Bunting-engineered automated control package.

CE Cerification

The Bunting® HF Series Drawer Magnet product line has earned the CE mark for the European Economic Area (EEA). The CE marking certifies that a product has met EU health, safety, and environmental requirements, which ensures consumer safety.
Other product highlights include:

• Pre-engineered for fast field installation.
• Transitions available for round, square, or rectangular spouting.
• Multiple trays of staggered magnetic cartridges provide increased contact with product flow for more complete metal capture.
• Order Ceramic, Alnico, or Rare Earth magnets to get the holding force right for your application.
• Specify mild or stainless steel construction.
• Housing design allows easy access to magnets.
• Self-cleaning models offer labor-saving convenience.

Introducing Bunting® Magnetics HF Continuous Cleaning Drawer Magnets

Pneumatic HF Series Drawer Magnets mean
no downtime saving labor costs.

• Tailored to your installation.
• Pneumatically powered cleaning mechanism releases ferrous contaminants into the discharge area automatically.
• Typically come in 2-row models but are available in 3- and 4-row trays.
• Pneumatic units can be installed in hard-to-reach locations.
• Ceramic magnets for general purpose catching of nuts and bolts.
• Neodymium Power-Balanced™ Rare Earth magnets for significant performance upgrade over ceramic at a moderate price.
• Neodymium High Intensity Rare Earth magnets for the highest level of performance in the industry. These magnets are extremely powerful.
• Cleans “on-the-fly” with no disruption of product flow.
• Patent Pending

Because of the special cartridge design, product continues to flow while magnets are being cleaned. There is no need for a gate to stop product flow. Each row of magnets are cleaned in an alternating pattern allowing the product to remain in contact with a row of magnets at all times.
