HENGST FILTERS
MATERIAL: R928024394
SUMMARY:
Quantity in stock: 0
Block mounting filters are suitable for direct attachment to pump blocks and manifolds. They are installed upstream open-loop or closed-loop controllers to be protected.
They basically consist 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 also an assembled bypass valve (5).
Via port I, the hydraulic 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 port 0, the filtered hydraulic fluid enters the pump block or manifold and thus 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 an oil drain plug (7).
Basically, the filter is equipped with mechanical/visual maintenance indicator (4). The electronic maintenance indicator is connected via the electronic switching element with 1 or 2 switching points (6), which has to be ordered separately. The electronic switching element is attached to the mechanical/visual maintenance indicator and held by means of a locking ring.

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 P must not be used, filter elements with glass fiber material have to 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.|

Filter installation
Compare the operating pressure with name plate information. Remove the blanking plugs from filter inlet and outlet, assemble the filter at the manifold ensuring an assembly without tension stress and considering the flow direction (direction arrows) as well as the servicing height of the filter element. The filter must preferably be installed with the filter bowl (2) downward. The maintenance indicator must be arranged in a well visible way.
Connection of the electric maintenance indicator
Basically, the filter is equipped with mechanical/visual maintenance indicator (4). The electronic maintenance indicator is connected via the switching element (6) with 1 or 2 switching points, which is attached to the mechanical/visual maintenance indicator and held by means of the locking ring.
Maintenance
Upon start-up in cold condition, the red pushbutton of the visual maintenance indicator (4) may jump out and an electrical signal is output via the switching element (6). Only push the red pushbutton in again after the operating temperature has been reached. If it jumps out again immediately or if the electrical signal has not gone out at operating temperature, the filter element must be exchanged or cleaned respectively after the end of the shift.
Filter element exchange
Switch off the system and discharge the filter on the pressure side. Screw off the filter bowl (2) and/or bottom (NG 1000) by counterclockwise rotation. Clean the filter housing in a suitable medium. Remove the filter element (3) from the spigot in the filter head by turning it slightly Check the seal ring and the support ring in the filter bowl for position and damage. If necessary, these parts are to be renewed. Replace the filter element H...XL and P..., clean the filter element G… . The efficiency of the cleaning process depends on the type of dirt and the amount of the pressure differential before the filter element exchange. If the pressure differential after the filter element exchange exceeds 50 % of the value before the filter element exchange, the G… element also needs to be replaced. Check whether the type designation and/or material number on the replacement element corresponds to the type designation/material number on the name plate of the filter. Install replaced or cleaned filter element on the spigot again by rotating it slightly. Now screw in the filter bowl and/or bottom to stop. Then screw out the filter bowl by 1/8 to 1/2 rotation again so that the filter bowl does not get stuck due to the pressure pulsation and can be easily released in case of maintenance works.|

The block mounting filters for hydraulic applications are pressure holding equipment according to article 1, section 2.1.4 of the Pressure Equipment Directive 97/23/EC (PED). However, on the basis of the exception in article 1, section 3.6 of the PEG, hydraulic filters are exempt from the PED if they are not classified higher than category I (guideline 1/19). They do not receive a CE mark.
Use in potentially explosive areas according to directive 94/9/EC (ATEX)
The block mounting filters are no equipment or components in the sense of directive 94/9/EC and are not provided with a CE mark.
When using the block mounting filters in potentially explosive areas, equipotential bonding has to be ensured.
According to DIN EN 60079-11, the electronic maintenance indicators WE-1SP-M12x1 are simple, electronic operating equipment not having an own voltage source. This simple, electronic operating equipment may - according to DIN EN 60079-14 - in intrinsically safe electric circuits (EEx ib) be used in systems for device group II, category 2G (zone 1) and category 3G (zone 2) without marking and certification. The operating equipment is assigned to explosion group II B and temperature class T5.
