In 1956, a professional engineer named A. Richard Ayers developed a product called the Pre-Vent. Richard needed a place to manufacture his new product so he founded Central Illinois Manufacturing Company (CIMCO) in Bement, Illinois. The Pre-Vent is a fill cap with a pressure and vacuum release that reduces evaporation in gasoline storage tanks and helps maintain the quality of stored fuel. Over 50 years later, the Pre-Vent cap is still being manufactured by CIMCO. The young company struggled to exist with job-shop contracts, while Richard continued his research on a fuel filter requested by a large petroleum distributor. In 1958, the Clean-Flow filter was introduced to the market. It was followed by a Gas-O-Line series, now known as our 200 line. Later CIMCO established the trade name Cim-Tek Filtration.
Over the years, the Company continues to innovate filtration and develop new products. It is a testament to our beginnings that all our original products — the Pre-Vent and 200 line filter — are available today. Now, Cim-Tek filters are available worldwide through our sales representatives.
Today, the Company continues as a family-owned and operated business. From the beginning, the key to success has been responding to customer needs in the changing world of filtration. Today, filtration is a necessity in a wide variety of petroleum, diesel fuel, hydraulic and industrial equipment applications. Our customers have come to expect us to provide quality and innovation.
