Oberlin Filter Company

Expertise in Filtration for Over Half a Century

At Oberlin Filter Company, we have upheld a singular vision for over 60 years: to engineer filtration systems that just really work. Our heritage is built upon a team of highly skilled professionals—comprising engineers, sales experts, designers, welders, plumbers, electricians, servicemen, and lab technicians. We collaborate closely with our customers to tailor the optimal system for their specific needs, crafting it with our own hands, overseeing its initiation, and ensuring unwavering support throughout the system’s functional life span. As a testament to our commitment, some of our filters have been operational for over four decades.

Family Roots, Global Reach

Our company takes pride in its family-owned roots, handed down through three generations of the Oberlin family, each committed to producing state-of-the-art automatic pressure filters. Wayne Oberlin, the pioneer, laid the foundation by constructing one reliable filter at a time. His legacy was expanded upon by his son, Tom Oberlin, who propelled our technology and our brand to the forefront of the liquid-solid separation industry on a worldwide scale. Grounded in meticulous engineering and in-depth application knowledge, we have flourished into an international enterprise that continues to be headquartered in Pewaukee, WI.

Engineering Excellence and Innovative Solutions

We are fundamentally an engineering-driven enterprise. Our engineers take the helm as project managers, ensuring the performance of your filters from concept to ongoing operation. Their responsibility is to oversee the journey of your order from the drawing board, through the production phase, to the startup, and beyond, always within reach for support.

Our Global Footprint

Oberlin Filter’s innovation and quality have crossed continents, establishing a robust presence internationally. Our manufacturing facilities in England and Germany not only craft our filters but also offer comprehensive sales, design, manufacturing, and service support across Europe. Additionally, our service agents are strategically positioned worldwide, marking our presence in over 30 countries with our renowned Oberlin pressure filters.

Versatile and Cutting-Edge Technology

Our technology serves a diverse array of industries, catering to four primary sectors: Metal Working Fluids for precise grinding and machining; Food industry applications, notably in hot frying and specialty oils; Advanced Chemical Separations; and a broad spectrum of Industrial Water Treatment solutions. Each application is unique and tailored, a challenge we embrace with enthusiasm. Our robust relationships with industry giants like GE, Veolia Water, DuPont, and a leading semiconductor producer in silicon wafer cutting underscore our adaptability and collaborative strength.

Our dedicated project engineers become your point of contact, bringing full accountability and seamless communication to the table.
