DFB...MA/DFB...QE High Pressure (Can Replace Hydac DF...MA/DF... QE Series )Filter

1.DFB... MA/DFB... QE series filters can be directly installed on system valve block, especially suitable for automatic control system and the servo system (can replace hydac DF...MA/DF... QE Series).

2.Filter basic construction
DFB...MA/DFB...QE series filter consists of the cover and the spin-on housing.
The DFB...QE filter bowl with the flow rate above 660 liter is integral type; below 660 is separated structure.  
2.1 Housing material
Filter cover: Ductile cast iron
Filter bowl: Carbon steel  
2.2 Seals
Perbunan (=NBR) (-30~+120°C);  Viton=FPM(-20~+200°C)
2.3 Filter element
Filter medium material
High strength carbon steel skeleton
2.4 Optional accessories
Without clogging indicator,with steel plug
Visual clogging indicator:CM-03
Electrical clogging indicator:CM-05
Combined visual /electrical clogging indicator:CM-08
Bypass valve(setting 6 bar)
2.5 Type of connection (choose according to filter model)
DFB...QE series filters installed with four holes
DFB...MA series filters installed with two holes
The top and bottom direction of inlet/outlet port  optional

Note: Type code   1.Normal inlet/outlet port(Integral filter bowl)         

                          2.Normal inlet/outlet port(Separated filter bowl)  
                          3. DFB...QE series 160.240.280 can choose outlet is on the top of inlet, /-0AI is added after the model. 
                          4.* represents filtration rating.

3.The total filter assembly pressure drop is the sum of housing and element pressure drop,filter selection calculated as per the following curves.
3.1 Housing pressure drop / flow rate characteristic curves
Housing pressure drop /flow rate characteristic curves are according to ISO3968, and suitable for the mineral oil with density  0.86 kg/dm³ and kinematic viscosity  30 mm²/s. 

3.2 Differential pressure / flow characteristic curves of filter element
The characteristic curves of filter element are suitable for the mineral oil with kinematic viscosity  30 mm²/s. Differential pressure and viscosity is proportional.
