5. About this product
The off-line filter FNS 040 is a device for filtration of hydraulic fluids and lubricants in the bypass flow.
A separate installation in the bypass or cooling circuit for fine filtration and discharge of the full flow filter is just as possible as the
filtration of fresh oil and the cleaning (flushing) of polluted systems for wear protection of components and systems.
The volume flow is dependent on the flow control valve used (see Chapter 8 "Technical data")
The operating temperature is in the range of -30° C to +100° C.

9. Operation
CAUTION
Exposure to spilled oil
Injury / risk of slipping
›If oil leaks, the oil-covered area must be shut of immediately and covered with an oil binding medium
(risk of slipping).
Static charge
Sparking
›There is a risk of static charge when using poorly conducting hydraulic or lubricating oils.
In this case, please consult the manufacturer.
NOTE
Reaching the maximum cleaning performance
›In order to prevent a short circuit of the oil flow, the distance between the suction and pressure connection should be kept as
large as possible.
The operation of the off-line filter FNS 040 is depending on the machine / system, in which the off-line filter is integrated and thus
cannot be further described here.
