Keller Bag Filter Magnets

Magnetic rod inserts for bag filters are cost-effective magnetic separators that can be used in conjunction with Keller’s bag filters to extend the life of filter bags by 5 times or more.

The removable stainless cleaning sleeve is included with all bag filter magnetic assemblies.
