Field of application
The duplex filter type F605 with the switch-over device A600 is a multi-purpose filter for liquid and gaseous
media.

Advantages
•
•
•
•

continuous filter operation during the cleaning phase
no interruption of the flow during the switching-over phase
low filter finenesses
quick replacement of the strainer if equipped with quick-release locks

Abstract
The duplex filter consists of two individual filters which can be operated alternatively or in parallel via 3-way
ball valve fittings. The single filters of the standard design consist of welded steel bodies provided with covers
which are fixed by means of bolts and nuts. The scope of delivery will comprehend the venting devices within
the covers and the drain devices within the bodies.
The filter can be equipped with basket or ring type strainers. The strainer inserts consist of a perforated plate
optionally covered with cloths having different mesh widths. The medium to be filtered will flow through the
strainer from the inside to the outside.

Safety advice
The filter with clamp lock is not applicable for the filtration of dangerous media (e.g. toxic, flammable or
caustic) and gases and respectively steam! In these cases cover lock with bolts and nuts, quick release lever
lock V150 or quick release cross-lock must be chosen.

Installation
The installation into pipings will be effected by means of flanges. Please ensure that the filter of the standard
design is vertically installed - with the cover located at the top without any additional loads - and mechanically
stress free. The medium to be filtered should enter the filter via the upper connection flange. A wrong
installation may lead to functional disturbances of the filter.

Commissioning / Instruction manual
1. Bring the switch-over into the wanted operating position (consider the position indicator)
2. Open the venting device until the liquid emerges
3. Close the venting device
4. The filtering bowl is ready to be used
Attention! As we are dealing with a pressure vessel, it should be ensured at any rate that the vessel is
absolutely pressureless prior to starting the maintenance work. The safety rules and the regulations for the
prevention of accidents required for the relevant medium have to be followed.

Switching-over procedure
1. Rotate the switch-over lever by 180° or the hand wheel up to the stop
2. Open the venting device of the filter bowl to be operated until the liquid emerges
3. Close the venting device. The filter has been switched over

Cleaning
1.
2.
3.
4.

Depressurize the filter bowl shut down using the venting or drain devices.
Loosen the filter lock and lift off the cover.
Using the drain device, empty the filter at least down to the level of the strainer support.
Pull the strainer insert out of the filter housing. Now the strainer can be cleaned by blowing out or blasting
using compressed air, steam or water. If necessary the strainer should be soaked and cleaned using a
suitable agent. Possibly an optimal cleaning will be obtained using ultrasonics. In case of all these modes
of cleaning, you should always take care not to damage the filter cloth.
5. During the reassembly following the disassembly procedure in the reverse, the sealing elements should be
checked if they are intact. If necessary they should be replaced.
