Return-line filters retain all the contamination created within the equipment and flushed out of the hydraulic circuit, thus preventing contamination entering the circuit via the tank and pump, with all its negative implications.
|
|
| The return line filter is an essential part of any hydraulic system. In many instances it is the only "system protection" provided and therefore must be carefully chosen to ensure maximum system efficiency. |

System Features
Hydraulic oil even when new will have a certain level of particle
contamination, and is typically graded at ISO 17/13/14. When oil
is added to a system further contamination can occur. Whilst
under operating conditions air and moisture, as well as particles
from seals and hoses, can add to the contamination and
degradation of the oil. Fitting a Filtakleen filter will not only
reverse this process but it will clean your oil so thoroughly it will
be cleaner than when it was new! |

In order to prevent paraffin separation and clogging of the filter at low ambient temperatures, pre-warming with electric heating elements or recirculation of fuel that has been warmed by the engine is used in our fuel filters.
For newer generations with even higher requirements, MAHLE has opted for two separate filter stages during water separation.
The first filter phase consists of a cellulose filter medium with an untreated melt-blown contact surface for increasing the contaminant absorption capacity. This melt-blown contact surface optimally causes the many small droplets to coalesce into larger ones. The particulate filter in the shape of a pleated star even agglomerates the finest water droplets.
The second filter phase consists of a water separator, whose hydrophobic fabric with a mesh width of 25 µm divides the barely stable emulsion, thus separating the water. As this occurs on the clean side of the filter, it is referred to as clean-side water separation.

Compressed air condensate generally has far more oil than
20 mg/l content. The user has two possibilities.
Firstly, he can have the condensate taken away by a specialist waste disposal firm at great cost. Alternatively, the user can process the condensate on site by separating the oil and the water, which forms the largest
proportion.
ZANDER’s ecosep S high efficient oil-water separator and
the ecodrain automatic drain, offer compressed air users a
complete condensate management system to achieve an oil content, in water of 10 mg/l or below which can be discharged into the effluent system.
-ecosep SL 1 - SL 60
Separating system for non emulsified compressor condensate. Usable to connect several condensate drain systems. The adsorption charcoal filters adsorb the remaining oil droplets and garant high safety in application.
Standard complete and ready for operation.
Optionally a heater is available.

Strainer
Sunfab strainer for separate installation on the suction pipe
Sunfab strainer type 150 is an inexpensive guarantee against operational stoppage due to contaminants such as welding blobs, brazing flakes, etc, which can often occur in the system, especially after new installations
Sunfab strainer is single use but can be flushed clean if necessary
Sunfab strainer type 150 functions as a coarse filter and does not replace the normal return filter
Sunfab strainer is intended for pump type SL. It must not be used with pump type SC because of the increased pressure in the suction pipe
|
|
| We have named PUMP CARE the Suction Filters because thanks to their function of protection from coarse contamination (due to lack of initiai cleaning or to an accidental ingression) they take care of the pump, ensuring a safe and efficient operation. |
