What are the most effective fluid filtration methods for metalworking coolants?

Membrane, paper bed, and magnetic filtration improve coolant quality, extend tool life, and reduce waste.

Coolant filtration removes solids, tramp oils, and bacteria, thereby protecting machine tools and extending the life of the coolant. PRAB offers a range of fluid filtration methods, including paper bed filters, membrane systems, magnetic separators, and hydrocyclones, each engineered for different contaminant loads and flow rates.
