GENERAL INFORMATION
Description Technical data
Return lter
RF2250 and RF2350 are ranges of return lters for side tank mounting
with integrated shut-off valve for protection of the reservoir against the
system contamination.
They are placed below the minimum oil level, directly connected to the
return line of the system.
The shut-off valve closes automatically when the cover is removed,
allowing the lter element replacement without the uid drop.
Available features:
- Female threaded connections up to 1” and flanged connections
up to 1 1/2”, for a maximum ow rate of 615 l/min
- Bypass valve, to relieve excessive pressure drop across the lter media
- Magnetic lter, to hold the ferrous particles
- Visual, electrical and electronic clogging indicators
Common applications:
- Compact mobile machines
- Compact industrial equipment

GENERAL INFORMATION
The curves are plotted using mineral oil with density of 0.86 kg/dm

Maximum ow rate for a complete return lter with a pressure drop ∆p = 0.5 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.
