Barnes International

What Barnes International does

Barnes International is an industrial manufacturer specializing in coolant filtration systems for metalworking and general machining applications. Founded in 1907 and headquartered at 814 Chestnut Street in Rockford, Illinois, the company operates as part of the Komline-Barnes family of filtration brands under parent Komline-Sanderson. Its product portfolio covers magnetic filters, deep bed gravity fabric filters (with magnetic drum pre-cleaners), permanent media rotating drum conveyor filters, coolant vacuum systems, and the KLEENALL-MAX regional filtration system, spanning flow rates from 10 GPM for individual machine tools to 20,000 GPM for total-plant central coolant filtration.

The underlying technology is largely mechanical and process-based: magnetic separation for ferrous fines, deep bed fabric media for water-soluble coolant applications, permanent-media rotating drums for chip and swarf handling, and vacuum systems for coolant recovery. The company holds ISO certification and emphasizes an extensive product warranty, targeting industrial manufacturers across steel cold rolling, steel strip cleaning, cast iron grinding, honing, lapping, polishing, and chip processing for aluminum, cast iron, steel, and plastics. A published case study with Hypertherm Inc. illustrates deployment at a 165,000 sq. ft. facility with 26 Swiss-style CNC lathes using a Star Filter system with 160 sq. ft. of filter media.

Barnes monetizes primarily through one-time equipment sales supplemented by recurring filter paper and parts revenue from its installed base. Go-to-market is direct and consultative: phone-led sales (800-435-4877), website contact forms, and a network of affiliated brands (Summit Filtration, Advanced Filtration Concepts, Superior Filtration, HydroFlow, Henry Filters) that extend reach across filtration sub-segments. Pricing is not publicly disclosed, consistent with customized industrial solutions, and marketing is supported by a technical blog, case studies, and a presence on LinkedIn, Facebook, and X.
