Efficient filter systems for hydraulic systems
Filtration Group Industrial filters increase the life and performance capacity of hydraulic systems by providing maximum fluid cleanliness. Innovative materials and technologies such as e-protect or PulseShieldTM permanently protect machinery and equipment against soiling and premature wear. Because the filtration systems are ruggedly built and equipped with high-quality filter media, FGI hydraulic filters withstand high pressure and rarely require maintenance. In addition to a large selection of original filter systems, Filtration Group Industrial also offers the high-quality filter elements as EcoParts for filter systems from other manufacturers.
Designed for use as a full or partial flow filter and for low pressure up to 25/60 bar, medium pressure up to 210 bar and high pressure up to 450 bar, Filtration Group pressure filters are precisely tailored to the requirements of the application as line filters, flange filters and filters in sandwich plate design. Robust housings, flow optimized design and a comprehensive accessory program always offer the right solution for all market requirements.

HIGH PRESSURE FILTERS
Duplex filters allow a filter change during live operation and are thus suitable for use in motors and drives that have to reliably run continuously. Thanks to the compact design, duplex filters require little space and have a low flow resistance.
LOW PRESSURE DUPLEX FILTERS
- Pi 210 / Pi 212, PN 32/63 bar, up to size 600
- Pi 214, PN 100/160 bar, size 300
- Pi 2100, PN 25/63 bar, size 40-400, according to DIN 24550
- Pi 2110, PN 40 bar, size 630+1000, according to DIN 24550
MEDIUM PRESSURE DUPLEX FILTERS
Whether installed in front of the pump or, for greater maintenance-friendliness, installed with maintenance indicator in the suction line for easy access from outside, they protect the pump from course impurities. With a wide range of system-compatible elements, the protection of systems and pumps in the fine range of 10 – 25 μm can be guaranteed with our MIC medias or in the coarse range with cleanable wire mesh.
All impurities generated in the system and flushed from the hydraulic system are collected by the return line filter, thereby preventing the development of a cycle of contamination through the tank and pump.
- Tank top return-line filter Pi 5000, size 40-100, according to Din 24550
- Tank top return-line filter Pi 5000, size 160-1000, according to Din 24550
- Tank top return-line filter Pi 530, size 35-50
- Duplex-tank top return-line filter Pi 5100, size 40-1000, according to Din 24550
- Plastic Tank top return-line filter Pi 5900, size 400 and 630
The combination of a suction filter and a return line filter improves the energy balance compared to a separate system. With the integrated preloaded valve, the pressure in the return line is not reduced, but rather is directly used for suction.
Corrosion and impact-resistance breather filters are used for impurity-free air supply of tanks. A large selection of system-compatible, changeable filter elements secures the required compatibility with the filter fineness of the hydraulic filters.
Oil filter module Pi 8300 for use in the primary flow
For gear oil filtration (primary and bypass flow) and for lubrication systems in wind turbines, Filtration Group Industrial has developed an innovative, compact oil filter module that increases and sustains the efficiency and service life of the hydraulic and transmission units. The system consists of a filter block with electric motor, gear pump, filter housing with highly efficient 2-stage filter element, pressure relief valve, non-return valve and maintenance indicator. It is available in two version with 110 l/min and 220 l/min volumetric flow. As a complete system in conjunction with an oil cooler, the oil filter module Pi 83116 ensures optimal filtration and cooling of wind power gearboxes and enables low-wear and maintenance-friendly operation.
Oil filter module Pi 8400 for use in bypass filtration
The newly developed filter module sets new standards in off-line filtration and is compatible with the previously used compact systems. The water-absorbing premium filter elements with PulseShieldTM technology filter with a fineness of 3 μm. They reliably separate even finest particles and oil aging products (varnish).
The use of filter elements can only be economically optimal when their dirt holding capacity can be fully utilized without risk. Mechanical or electronic sensors integrated in the filters or installed later respond to continuous changes in the pressure conditions that vary by contamination level and indicate them either via manometer or optical and optical-electrical switches, depending on design. With suction filters, low pressure is registered, while with pressure filters differential pressure is registered and with return line filters the dynamic pressure is registered. The operator can determine the optimal time for changing the filter elements without risk.
Always specifically tailored to the required purity class, the pressure conditions and the properties of the medium, Filtration Group’s stable and differential pressure-resistant filter elements ensure trouble-free and economical operation with a high level of dirt-holding capacity. In our comprehensive program of standard and DIN designs, you will also find alternate versions for virtually any filter brands, as well as filter elements for aggressive fluids, cooling lubricants and aqueous media.
Upon request, we also develop special customer-specific versions.
