Running a Successful Business Since 1980
Filtration Systems Inc. was founded in 1980 by Richard Bayerlein, P.E. with his son Doug Bayerlein, BSME Southern Methodist University.
From the beginning, Richard and Doug worked together using their engineering background , expertise, and innovation to create a world-leading filtration manufacturing company. Only the highest quality of materials are considered, and we are proud to say, Made In The USA! The FSI corporate campus and manufacturing plant is located in Waukesha, Wisconsin. From the inception of the company, strong partnerships were formed with a number of leading OEM’s optimizing engine filtration. FSI specializes in meeting specs and passing validation testing ensuring compliance for a large number of well known OEM companies. Innovative filtration for the Energy Sector is our specialty with providing enhanced robust filters that provides higher efficiencies in conjunction with longer change-out intervals. This is also imperative working in the Oil & Gas Industry, specifically Natural Gas Filtration although we are likewise heavily involved in engine filtration. We are a solution-based company working to optimize filtration by understanding the needs of our customers. We go to market with both OEM’s and approved Distributor networks world-wide. We are proud to be an ISO-9001 approved manufacturer. We believe what separates us from others in the industry is our dedication to customer support and service. Our success is measured by our customer’s success.
