Barnes PE-25 Fabric Coolant Filter | 28 GPM | 1992 | S/N TCF-9212

Barnes PE-25 Gravity Fabric Filtration System | 28 GPM | 1992

The Barnes PE-25 is a high-efficiency "Deep Bed" gravity filter designed for the continuous removal of metallic and non-metallic contaminants from machine tool coolants. By utilizing a continuous roll of filter media, the PE-25 ensures that your grinding, honing, or milling operations are always supplied with clean, debris-free fluid. This not only extends the life of your coolant but also significantly improves workpiece surface finish and protects expensive machine tool spindles and ways.

Manufactured in 1992 (S/N TCF-9212), this unit is built with the industrial-grade durability that made Barnes the industry leader in coolant management. The system features an automatic float-controlled indexing drive that advances fresh filter paper only as needed, ensuring maximum media efficiency and minimal operator intervention.
