About Us


Founded in 1905, The Hilliard Corporation has evolved from a one-product business into a special-applications engineering company serving customers worldwide. The Hilliard Corporation offers a broad line of motion control products, oil filtration and reclaiming equipment, starters for industrial gas and diesel engines and gas turbines, and plate and frame filter presses used in the food and beverage industry. Our filtration systems are sold under the trade names of Hilco and Star Filters.

Hilliard products are designed, manufactured, and sold according to our customers’ applications. As a result, we have a large range of custom-engineered products that can be modified to meet new applications. With a sound understanding of engines and filtration devices, Hilliard engineers design complete systems, including electromechanical interfaces. Hilliard often works with customers to research and test products, acting as a lab for specific applications.

At Hilliard, quality is a way of doing business. Each of our processes is documented to regulate operation, even on very short production runs. Experienced machinists and code welders work efficiently to keep operating costs low while transforming blueprints into products. Following documented processes, these craftsmen use bar-coded, computerized production controls to guarantee high-quality output.

Our goal is to manufacture products that solve customer problems. Over the years, we’ve found that the only way to reach that goal is to be flexible. We’re willing to modify existing products, or develop new ones, respond quickly to requests, and take on complicated projects for sophisticated applications. In short, we will work with you to get the job done.

We welcome your inquiries, your challenges, your business.
