Function, section
The tank breathing filter guarantees air exchange in the fluid tank. Depending on the machine cycles, air can be pulled into the tank with contamination when a breather filter is not used. A tank breather filter will accomplish both the
pressure equalization and air filtration preventing contamination from entering the tank through the air exchange.
It basically consists of a threaded cover (1), a filter element (2) and a bottom housing (3) to accommodate the filter element.
The contaminated air is transported through the filter element into the hydraulic tank (T) via the opening (A). Only filtered air enters the tank. Escaping air is also directed through the filter element.
Version TLF I 1-25 ... 6-80
All sizes have an internal thread.
Version TLF II 1-25 ... 6-80
All sizes have a male thread.
Version TLF III 1-25 ... 6-80
All sizes have a male thread. Version III also has a 130 μm filling strainer (4).
When air humidity is high or when there are large temperature variations, the exchanged air may condense and promote the oxidation process of the oil. This leads to corrosion and damage to the fluid tank.
In this case, we recommend use of our “AS10” waterabsorbent filter material to dry the incoming air.

Important information on hydraulic fluids:For more information and data on the use of other hydraulic fluids, please refer to data sheet 90220 or contact us.
• Flame-resistant - containing water: due to possible chemical reactions with materials or surface coatings of machine and system components, the service life with these hydraulic fluids may be less than expected. Filter materials made of filter paper (cellulose) must not be used, filter elements with glass fiber material must be used instead.
• Bio-degradable: If filter materials made of filter paper are used, the filter life may be shorter than expected due to material incompatibility and swelling. |

Assembly, commissioning, maintenance
Assembly
The filter connection must correspond to the tank connection. Install the filter on the tank. When installing the filter, the required servicing height of the replacement filter must be taken into account. For servicing reasons, we recommend installing the filter in a vertical position. All filter components must be tightened manually.Commissioning
It is not necessary to commission the filter.Maintenance
Exchange of the filter element
No maintenance indicator is provided, but the filter element must be changed at minimum every 6 months. Since the ambient conditions are very different depending on the place of installation, we recommend considering more frequent replacement of the filter element according to the specific installation conditions for TLF tank breathing filters.Notice:
Vacuum switch (upon request) for monitoring the suction pressure can be mounted on the tank separately.
Warning!
The filter must not be operated without a filter element
Notes:
All work on the filter must be performed by trained specialists. Proper function and safety are only guaranteed if original Bosch Rexroth filter elements and spare parts are used. Warranty becomes void if the delivered item is changed by the ordering party or third parties or improperly mounted, installed, maintained, repaired, used or exposed to environmental condition that do not comply with the installation conditions.Tightening torques MA in Nm for screw-in cartridge valves
