General information1

1.1 Disclaimer

The preparation of this document was made as carefully as possible. However, errors can not be

excluded. Therefore, we do not take over any liability for errors or deficits in this document, nor for

any consequential damages which may arise there from.

We reserve the right to make technical changes to this document or the product described herein

without notice.

1.2 Symbols used

The following symbols are used in this document to visually emphasize important information and

warnings:

Note

Note on special tips and other helpful or important information.

Attention

Disregarding these instructions may damage the fuel filter or the mashine where the

filter is mounted.

The filter may be under pressure. Therefore never open a filter in operation, otherwise fuel may leak

into the environment and the engine draws air, which can cause damage to the engine.

When using duplex or switchable filters, the lever position indicates which filter is in operation. At

this moment the other filter is isolated from the fuel circuit, but still could contain fuel.

Filters with fuel pre heating systems may only be placed in operation when completely filled with

fuel and primed of air.

The electrical current for the heater must never be turned on without grounding and activated

associated control system.

Remove spilled fuel immediately and dispose them in accordance with the applicable statutory

provisions (s. cha. 12).

1.4 Intended use

The filter is intended for the filtration of diesel fuels and mineral oils with a dynamic viscosity < 10

mPas, flash point > 55 °C and boiling point > 160 °C and is designed for operation in between fuel

tank and fuel lift pump (suction side). The filter should never be installed on the pressure side,

behind the fuel pump.

Introduction2

2.1 Why Separ

In 1992, the generation SWK-2000 water separators / fuel filter was developed by the company W.

Lösing Filtertechnik e. K. as an effective system for the separation of water and dirt particles which

are contained in the fuel. Both water and dirt can lead to high wear and tear on engines as well as

the injection systems and result in expensive, intensive repairs and equipment down time.

SWK-2000 offers:

Smallest and most compact design

High separation efficiency

Low flow resistance

Long life filter element

Easy installation

Simple maintenance

Different flow rates

Minimal maintenance effort

Enviroment friendly

2.2 Function of the SWK-2000

The separation and purification process using a special patented system that is used throughout all

of the different sizes, which stick out through most compact design in relation to the effective flow

rate.

Generally, the SWK-2000 is installed on the vacuum side of the fuel system, i. e. between fuel tank

and fuel pump.

The fuel enters the filter through one of the two inlet parts, the unused port must be sealed off with

the attached plug.

Stage 1

From the inlet port, fuel flows into the filter and passes an interior vane system whereby the fuel is

moved in an intensive circular motion.

Stage 2

The centrifugal gravity, resulting from the circular motion, forces the fuel to the outer wall of the

bowl. The heavier water droplets and heavier particles collect on the wall of the bowl and settle due

to natural gravity to the bottom of the bowl.

Stage 3

In the further flow the fuel passes the outer vane system. By

the different length of the vanes and the twofold change in the

fuel flow direction, smaller water droplets and fine dirt

particles settle on the vanes, where they agglomerate and than

decline, caused by gravity, down to the bottom of the bowl.

Already at this point the major portion of any contaminates in

the fuel have been separated.

Stage 4

Below the filter element, on the so-called dome, the flow

cross-section is considerably increased, whereby a slow-down

of the fuel occurs. This also allows smallest water droplets and

dirt particles to settle. Through the previous pre-separation,

the majority of the contamination (water and dirt) settles in

the bowl and prolongs significantly the lifetime of the filter

element.

Stage 5

The remaining suspended contamination in the fuel, finest water droplets and smallest particulates

are filtered by a replaceable filter element which is produced from a special cellulose paper or

stainless steel mesh elements.

The clean fuel leaves the filter through one of the outlet ports (the port not required should be

sealed off with the plug attached) and continues through thefuel system.

2.3 Fields of application of the filter

Vehicle industry –trucks, busses, crane trucks, municipal vehicles, etc.

Construction machinery, agricultural machinery, forklifts, compressors, etc.

Ship propulsion motors, auxialliary units

Stationary engines and generators, welding and pumping units

Mining machinery, rail vehicles

There are also versions available for special applications.

Specifically for marine or prime power application duplex or switchable filters are offered. Thereby a

filter can always be serviced, while the other filter is under flow without engine shut down.

For engines burning biodiesel appropriate versions are available.

For winter operation the SWK-2000 filter is available with pre-heating systems.

For hot environments there are custom high-temperature variants available.

Delivery3

3.1 Scope of delivery

Check if you have the following accessories:

3.2 Unpacking

Before opening check the delivery for outer damage.Report any damage to carrier.

DISPOSAL

Please follow the environmental guidelines and laws of your country. Make sure the

the packaging material is disposed according to applicable regulations.

3.3 Storage

The filter and its accessories must be kept dry and in compliance with the maximum permitted

temperature ranges (s. chap. 5.8).

During a long storage period you should close all openings on the filter in order to protect the

interior and the filter element from unnecessary pollution. All filters out of the factory have all ports

sealed with plastic plugs.
