For many decades now, RT-Filtertechnik (formerly Regeltechnik Friedrichshafen) has worked together with its customers to develop top-standard filtration systems, filter elements and accessories. Over the years, it has become a synonym for competence and now stands for effective filtration, user-friendliness and optimal environmental compatibility. What do we mean by effective filtration? A careful choice of glass-fibre fabric based on years of experience and practical testing. Consistent use of magnetic pre-filtration. Magnetic pre-filtration has a special advantage in that it retains both ferromagnetic and non-ferromagnetic particles, from the very small to the very large. This not only prevents clogging, but also ensures that very large impurities such as welding beads are filtered out of the hydraulic fluid, thus effectively relieving the strain on the filter element and prolonging its lifetime considerably. At the same time, the flow direction from the inside of the filter element outwards prevents any solid particles from being washed back into the hydraulic system during filter maintenance. User-friendliness is a key feature. Maintenance tasks are extremely easy to perform, as the filter element is always removed from above. This prevents any oil from escaping when the filter element is changed, so that there is no risk to the environment		Large-scale construction machinery Airport machinery fleet, industrial trucks Truck-mounted crane Hydraulic units Mobile cranes / offshore construction machinery Test bench filters Concrete pumps Cooling apparatus Wheel loaders Automobile crane applications Suction dredgers Environmental engineering Machine tools
	Large-scale construction machinery For construction machines such as this mining excavator, RT-Filtertechnik has worked together with the customer to develop special filters which are capable of filtering several thousands of litres per minute with a high degree of efficiency and an above-average service life.   Airport machinery fleet, industrial trucks Airport working environments demand mobility, durability and thermal stability - just the qualities offered by RT suction-return filters and RT return filters, as seen here at Frankfurt airport.   Truck-mounted crane Truck-mounted devices call for compact, simple and long-lasting hydraulic components. The standard series from the RT return filter range fits this bill perfectly, and has been used successfully for a number of years.   Hydraulic units From compact units to large-scale systems - nowadays, filters are only used in this field after careful examination of the costs. Here too, RT suction filters and RT return filters have proved highly successful.   Mobile cranes / offshore construction machinery Mobile cranes, cable dredgers, drilling gears and offshore construction machinery for rough conditions all require efficient, made-to-measure filters. The RT service team for the joint development of filtration solutions ensures long-term customer satisfaction.   Test bench filters RT test bench filters draw on years of experience with exceptional criteria such as extreme temperatures or aggressive fluids. We are always ready to accept new challenges!   Concrete pumps Whether suction filters for closed circuits or return filters in open hydraulic circuits - the required standards are equally exacting. The use of RT filters world-wide in the concrete pumps of famous manufacturers is a testimony to their reliability.   Cooling apparatus Our large-capacity, pressure-vessel type suction gas filters are used for all common refrigerants in cooling apparatus. High-quality materials and a high filtration rate guarantee low running costs and excellent economic efficiency. Certified by major international qualification authorities.   Wheel loaders These versatile construction machines present the manufacturer with one of the biggest challenges, as they need to be fully operational at a momentīs notice, whatever the temperature. Needless to say, the RT suction-return filters developed specially for this purpose master this challenge with characteristic ease.   Automobile crane applications Precise movements coupled with a highly compact and economical design are also often required in mobile applications. RT standard filters cater to all the requirements of this sector, such as price/performance ratio, reliability and long life.   Suction dredgers Suction dredgers are highly environment-friendly, ultra-modern machines capable of moving earth quickly and efficiently, even in the most sensitive areas. Similarly, the use of RT filters ensures high efficiency and environment-friendly maintenance of the hydraulic system.   Environmental engineering Life isn't easy for mobile machines in the environmental engineering sector. They are expected to be environment-friendly yet super-efficient under tough operating conditions out in the field or at the scrapyard or recycling plant. This is where RT filters come in, as used in the well-known Doppstadt machines, for example.   Machine tools Quick, precise movements controlled by high-pressure hydraulics depend on optimally filtered oil. We recommend RT line filters for all pressure ranges.
