About FSI

Innovative Solutions. Clear Results.

FSILeading the world with innovative products & solutions

FSI is the industry leader in innovative, state-of-the-art filtration products and solutions. With over 48 active patents, including Polyloc® ring and Polymicro® seamless filter bags, we continue to provide our customers solutions to their filtration needs.

In 2004, FSI was recognized by the Automotive Industry when we received the Automotive News Pace Award for FerrX 5000® Magnetic Separator. The patented FerrX 5000 is uniquely designed to remove ferrous materials from the effluents used to clean and rinse the surface of welded body units prior to the paint application.

Established in 1972 in Michigan City, Indiana, FSI has grown into a worldwide supplier of superior-value filtration products and solutions.

Complete Manufacturing Control

An important factor in our competitive edge is that we maintain complete control over the entire manufacturing process: FSI extrudes fiber, needles felt, mold injects plastic components, sews/welds filter bags, and manufactures a complete cartridge line. In addition, we engineer and fabricate ASME-code filter housings and equipment.


Advanced Laboratory Facilities and Filtration Experts

Other factors which allow us to lead the industry are: our products are manufactured in a silicone-free environment, we have advanced laboratory facilities located in Soddy Daisy, Tennessee, and we have a highly educated team of filtration experts.

FSI distributors and sale representatives continue to build upon their knowledge base and skill each year as application successes are shared and disseminated among our in-field and laboratory experts. By sharing process engineering successes and challenges with each other, our company is able to provide proven applications solutions to all types of industries. In many cases, such solutions have saved our customers tens to hundreds of thousands of dollars annually.

Bottom-line performance

Our goal is to help our customers provide the highest levels of product quality and output while helping them improve their bottom-line performance.
