Description Technical data
Stainless steel high pressure  lters
In-line
Maximum working pressure up to 70 Mpa (700 bar)
Flow rate up to 50 l/min
FZH is a range of stainless steel high pressure  lter for
protection of sensitive components in high pressure
hydraulic systems placed in difficult environmental
conditions.
They are directly connected to the lines of the system
through the hydraulic  ttings.
Available features:
- 1/2” female threaded connections, for a maximum
ow rate of 50 l/min
- Fine  ltration rating, to get a good cleanliness level into
the system
- Bypass valve, to relieve excessive pressure drop across
the  lter media
- Low collapse filter element “N”, for use with filters
provided with bypass valve
- High collapse  lter element “H”, for use with  lters not
provided with bypass valve
- Low collapse  lter element with external support “R”,
for  lter element protection against the back pressure
caused by the check valve or the reverse  ow in  lters
provided with the bypass valve
- High collapse  lter element with external support “S”,
for  lter element protection against the back pressure
caused by the check valve or the reverse  ow in  lters
not provided with the bypass valve
- High collapse  lter element “U”, for use with aggressive
uids
- Visual, electrical and electronic differential clogging
indicators
Common applications:
- Off-shore equipment
- Water  ltration systems
- Systems with strong or corrosive environmental conditions
- Systems with corrosive  uids

Maximum ow rate for a complete stainless steel high pressure lter with a pressure drop ∆p = 1.5 bar.
The reference uid has a kinematic viscosity of 30 mm
2
/s (cSt) and a density of 0.86 kg/dm
3
.
For different pressure drop or uid viscosity we recommend to use our selection software available on www.mpltri.com.
You can also calculate the right size using the formulas present on the FILTER SIZING paragraph at the beginning of the full catalogue or at the beginning of the lter family brochure.
Please, contact our Sales Department for further additional information.
