Filtration Systems


Whether you are using a water-based or an oil-based coolant system, coolant filtration is essential to maintain industrial machinery. Keller’s coolant filtration products remove sludge and chips from coolant sumps – including particles as small as 1 micron in size.

In-line bag filter assemblies are ideal for protecting cutting tools and spindles.

Bag filter magnetic assemblies clean steel and iron chips from coolant or oil and extend the life of the filter bags.
