The return flow filter is a particularly economical way to ensure thorough oil or hydraulic fluid filtration while the machine or system is in operation. Return flow filters are able to capture all the dirt that is generated and flushed out in hydraulic systems. This prevents a possible dirt circuit via tanks and pumps.
In principle, the filter fineness of the return filter must be adapted to the pressure filters of the hydraulic system in order to prevent dirt ingress and abrasion caused by wear downstream of the pump from entering the tank.
Return flow filters can optionally be equipped with an additional ventilating filter to compensate for atmospheric pressure differences in the tank.
Intended for mounting on tanks as a single filter or as a double-switch filter, allowing loss-free switching of the fluid flow without interrupting operation. With a return filter upstream of the tank, fewer particles enter the tank, which significantly reduces wear on the priming pump and downstream components in the fluid circuit. We offer a wide selection of filter systems and replacement filters from reputable manufacturers with high-quality filter media. Ask for original equipment parts or equal or higher quality replacements from other manufacturers.
Inline filters with spin-on cartridge are suitable for use in suction, return or low-pressure lines. They are available both with and without bypass. We offer a wide range of products from well-known manufacturers such as Filtrec, Filtration Group or Donaldson with a wide variety of filter media depending on the application and field of use. Besides cellulose, which is more and more replaced by glass fiber media because of its better efficiency, wire cloth is also used in some applications. We will be pleased to advise you.
