When you need to use a hydraulic filter, and changing the filter element without stopping your system, then you need to use Change over (Duplex) filter, which let you easily changing the filter element while operation.

SERIES     MDD – HDD

Application : Can be mounted in suction, pressure or return lines.
Port size: up to G 1 , up to SAE 2 ” Avit2″
Working pressure : up to 315 bar   Flow rates: MDD up to 95 I/min, HDD up to 1350I/min
Filtration materials : Paper, interpor fleece or Stainless steel wire mesh.
User benefits : duplex filters can be maintained without Interruption of the operation.
The upper part has a three-way-change-over valve Which allows to change – over the flow from the dirty filter
Side to the clean filter side without interruption.

SERIES     DU – DUV

Application: The flow path through the filter can be changed to either of the two chambers.
For mounting in suction , pressure of return lines.
Port size: Up to G 3/4 up to SAE 5″
Working pressure: 32 bar  - Flow rates : DU up to 4000 I/min, DUV up to 2000 I/min
Filtration materials: Paper ,interpor fleece or stainless steel wire mesh
User benefits :Rotary slide- or ball valve, which is Integrated in the middle of the housing , makes it possible
to switch from the dirty filter side to clean filter side Without interrupting the operation. The dirty element can
Be serviced or changed while in the “off” position.

SERIES    DSF – DNR

Application: the flow path trough the filter can be changed to either or the two chambers.
For mounting in suction, pressure or return lines.
Port size : in DIN or ANSL flanges up to 10″
Working pressure: 25 bar, 16 bar
Flow rates : DSF up to 10 000 I/min, DNR up 8000 I/min
Filtration materials : Paper, interpor fleece or Stainless steel wire mesh
User benefits :A three-way change-over valve which Is integrated in the middle of the housing makes it
Possible to switch from the dirty filter side to the clean filter side To the clean filter side without interrupting the operation

SERIES     DA – DNA
Filters according to ASME design
