The 110LE(N) inline filter is suitable for direct installation into pressure lines. It is installed upstream components to be protected.

It basically consists of filter head (1), a screwable filter bowl (2), filter element (3) as well as mechanical/visual maintenance indicator (4). In case of filters with low-pressure-differential-stable filter elements (= code letter pressure differential A), there is an assembled bypass valve (5) by default.

The installed spring (6) prevents possible vibrations of the filter element (3). During disassembly, the contact pressure of the spring (6) holds the filter element in the filter bowl (2).

Via the inlet, the fluid reaches the filter element (3) where it is cleaned. The dirt particles filtered out settle in the filter bowl (2) and in the filter element (3). Via the outlet, the filtered fluid enters the hydraulic circuit.

The filter housing and all connection elements are designed so that pressure peaks - as they may e.g. occur in case of abrupt opening of large control valves due to the accelerated fluid quantity - can be securely absorbed. As of size 0160, the standard equipment comprises a drain screw (7).

By default, the filter is equipped with mechanical/visual maintenance indicator (4). The electronic switching element (8) which has to be ordered separately is attached to the mechanical/visual maintenance indicator (4) and held by means of a locking ring.

The electronic switching elements with 1 or 2 switching points are connected via a mating connector according to IEC 60947-5-2 or via a cable connection according to EN 17301-803.

As of size 0130, it is possible to order the filters with threaded couplings for separate pressure differential measurement. Only then will the filter head be drilled accordingly.

High filtration performance due to the tangential cyclone-effect flow path in the filter housing in connection with a slowdown zone at the bottom of the filter bowl.

Notice:

If the maintenance indicator for the element exchange is not observed, the bypass valve will open if the pressure differential increases. In this way, one part of the flow reaches the clean side of the filter without being filtered. Thus, effective filtration is no longer guaranteed.

Inline filters are used in hydraulic systems for separating solid materials from the fluids and lubricating oils. They are intended for attachment in pipelines.
