Filter technology from HANSA‑FLEX
High-quality filters and filter elements
HANSA‑FLEX hydraulic filters reduce solid particle contamination in fluid circuits and protect sensitive components. With filters and filter systems from HANSA‑FLEX, you can be sure that your oil meets the required level of cleanliness and retains its optimum fluid properties.
- Filters, filter elements and filter housings
- Adsorber, pressure, return, suction and spin-on filters
- Line filters, replaceable filters and suitable accessories
The perfect filter solution for all hydraulics applications
Suction filter used as a protective filter
- Installation: submerged in the tank
- Permissible operating temperature: -25 °C to 110 °C
- Note: not suitable for depth filtration
Pressure filter used as a working or protective fi
Pressure filters are used with high system pressures. They protect the system and sensitive components such as proportional valves and servo valves from contaminants.
- Compact design
- Flow-optimised, durable filter housing
- For low, medium and high pressures (up to 60, 320 and 450 bar)
Return flow filter used as a depth filter
Return flow filters are installed in the return line ahead of or on the hydraulic tank. They filter the oil before it returns to the tank and capture the dirt particles created in the system. This ensures that no contaminants from the system find their way into the tank and that they do not circulate within the system. Bypass valves are frequently integrated into hydraulic systems to protect them and the rest of the filters from excessive blockage pressures in the return flow line.
Spin-on filter used as a suction filter or return
Spin-on filters consist of a diecast aluminium filter head and a replaceable screw-on metal filter cartridge.
- Easy replacement of the filter element
- Compact design and simple construction
- Excellent cost-benefit figures
It all comes down to correct design and dimensioning
Our experts know the importance of correct design and dimensioning for achieving the best filtration performance.
As fluid experts, we offer you a comprehensive range of filter elements such as suction, pressure, return and spin-on filters for use throughout your fluid systems. We also support you in designing and dimensioning your filters. We take into account the following important factors:
- Volume flow and viscosity of the fluid
- Desired oil cleanliness and amount of contamination
- Required filter service life, size and type of system
- Filtermedium
High-performance filtration
In addition to high-performance filters, the HANSA‑FLEX product portfolio lists more products for effective fluid care, such as filter systems, oil analysis sets, particle counters and oil binding agents.
Filter systems for cleaning fluids
Quality and cleanliness requirements for oil in hydraulic systems are continually rising. With HANSA‑FLEX filter systems, you benefit from an effective care regime for your hydraulic oil, which also contributes to fault-free operation of your hydraulic systems.
- Partial flow filter systems for purchase or hire
- Oil service equipment and accessories such as equipment carriers for transport
- Mobile filling pumps for cleaning oil while filling tanks
- Replaceable filter elements
Devices and instruments for oil analysis and sampling
Using sensors, rapid testing devices and oil analysis sets, you can implement a comprehensive fluid condition monitoring regime and perform other tests.
- Oil analysis devices with suitable accessories
- Particle sensors, particle counters, vacuum filtration devices
- Oil analysis sets for mineral, bio- and gear oils
- Fluid sampling sets and sample bottles in glass or plastic
- Vacuum hand pump
Hydraulic fluids and oil binding agents
We can supply you with hydraulic and engine oils for automotive, industrial, construction uses, agriculture and forestry machines. Also available are highly absorbent oil binding agents to clean up surfaces where oil has dripped or escaped.
- Transmission and hydraulic oil
- Mineral oil-based engine oil
- Hydraulic oil based on plant or mineral oils, and synthetic oil
- Oil binding agents (granules, mats, natural fibres)
- Oil stain removers
HANSA‑FLEX solutions for sustainable oil filtration
Our know-how on every aspect of fluid technology is reflected in our record of product development. Here are some details of two of these products for filtering fluids.
Oil care made easy with mobile filling pumps from HANSA‑FLEX
These CE-certificated filling pumps with two-stage filtration clean fresh or old oil while filling or emptying oil tanks. The high-performance motor allows a continuous duty cycle of up to 3 hours.
- Volume flow 15 l/min, 230V AC motor with brand-name quality
- Integrated oil containment tray and visual clogging indicator
- Permissible operating temperature of -20 °C to +110 °C
Protect hydraulic systems from condensation water with adsorber filters
Adsorber filters are bolted onto the system and provide comprehensive protection in environments with high relative humidities, large temperature fluctuations or where biologically degradable oils are used.
- Suitable for interior and exterior use, for tanks, drums and IBC containers
- The silica gel changes colour to show the water saturation level of the filter
- An integrated 3 µm filter element also contributes to clean oil
