About RT-Filtertechnik
The flexibility of a medium-sized company combined with cutting-edge technological expertise: As an established filter manufacturer with headquarters in Friedrichshafen on Lake Constance, we develop filtration systems, filter elements, and accessories of the highest quality. We serve our customers both as a development partner and an original equipment manufacturer. We take pride in our service performance – with the clear goal of keeping your systems reliable and highly efficient. We design and manufacture high-performance, custom filters tailored precisely to your technical specifications.
Our core product range at a glance
- Highly advanced product families: our product range includes precisely engineered suction filters, return line filters, combined suction-return line filters, robust inline filters and highly efficient magnetic cores designed to reliably capture even the finest metallic particles.
- Strategic areas of expertise: we offer proven solutions in mobile hydraulics and industrial hydraulics, excel in the technically challenging process of separating air from oil, set standards in application-specific media technology, and manufacture certified systems for cabin air filtration in extreme conditions.
Your filter specialist for complex engineering challenges
Standard catalogue products quickly reach their physical and structural limits when used in highly specialised industrial applications. Anyone seeking an experienced filter specialist to solve custom filtration problems isn’t looking for standard components. They want engineering-driven solutions to complex challenges.
The critical question that often comes up during the design phase is which B2B filter manufacturer develops custom filters for mobile hydraulics that can withstand extreme pressure pulsations? RT-Filtertechnik bridges the gap between development and mass production. By combining a deep understanding of physical systems with decades of field experience in hydraulic filtration, we eliminate the risk of component failure due to inadequate filtration as early as the design phase.
Development expertise since 1949: milestones as your quality guarantee
The history of our company is more than just a chronological sequence – it forms the foundation of our technological validation. Every strategic investment made over the past decades ensures the performance and reliability of your systems today.
| Year | Historic milestone | Direct value-added benefits for B2B customers |
|---|---|---|
| 1949 | Company founded; collaboration with world-renowned pioneer Prof. Dr.-Ing. Hans Thoma and the development of the first magnetic filter. | Over 75 years of expertise as a filter manufacturer: deeply ingrained physics expertise safeguards your systems against metallic abrasion. |
| 1960 | Securing the Liebherr Group as a client and establishing a development partnership that remains successful to this day. | Maximum stability: tried-and-tested OEM-level processes guarantee absolute process reliability for your mass production. |
| 1992 | A specialised subsidiary was established in Kromsdorf near Weimar, dedicated to filter element production. | Scalability & focus: maximum precision and fast availability are achieved through specialised production facilities. |
| 2008 | Commissioning of one of the world’s most powerful dynamic multipass test benches (800 l/min). | Assurance through measurements: a realistic simulation of actual pressure curves prevents unexpected system failures. |
| 2011 | A major expansion in assembly capacity, including a new production hall in Kromsdorf (900 m²) and two-shift operation in Friedrichshafen. | Delivery reliability thanks to mass production capacity: ensuring a secure supply, even in the face of volatile market demands. |
| 2012 | New production facility in Kromsdorf (900 m²) | Expanding capacity to enable faster response times: increased manufacturing space enhances flexibility and delivery performance as production volumes grow. |
| 2018 | New production facility in Kromsdorf (1,800 m²) | Long-term supply security: doubling the production area creates robust capacities for series production launches and international growth. |
Maximum manufacturing expertise for your operational reliability
A modern filter manufacturer musn't just promise quality. They also need to be able to conclusively prove it through measurements. When it comes to the question of where custom-made, complex filter elements can be tested and manufactured, we respond with an infrastructure that sets international standards. We don’t limit ourselves to standard solutions; instead, we design custom housings and structures tailored to individual filter requirements.
Validated infrastructure for error-free series
As a German filter specialist, we transform theoretical requirements into reproducible, top-quality results:
- Laboratory and test facility capacities: our laboratory division continuously conducts fundamental research and develops custom solutions (such as complex tank optimisations).
- Real-world simulations: If you're looking for a filter manufacturer with a modern multipass test bench that simulates real-world pressure conditions, our test facility can provide precise, data-driven evidence of separation performance under actual operating conditions, with a capacity of up to 800 l/min.
- Precision manufacturing: we use state-of-the-art ultrasonic machines, specialised saws, and automated bonding systems to ensure the absolute integrity of the filter media.
Long-term series production and development partnership
A reliable German filter specialist for long-term series production and development partnerships stands out by keeping the overall cost-effectiveness (TCO) of your system in mind. Our strategic focus is on continuously improving the filter element and seamlessly integrating the filtration systems into your existing infrastructure to ensure immediate performance gains.
From the initial layout design and prototype validation in test facilities to a reliable supply with two-shift operation, we solve complex challenges with precisely tailored, custom filters.
