The PTU3 Filter Separator is a portable off-line oil filtration system / oil separator, combining fine filtration with water separation all in one unit, with an integrated variable speed driven circulating pump. They are designed for use in applications containing hydraulic oil, diesel fuel, lubrication oil, and others, in which water condensation or  ingress is a constant or recurrent problem.


It can also be customised to function as a Filter Separator removing water by coalescence, while at the same time minimize oil contamination levels of particles and oil degradation products (oxidation resin/sludge, varnish).  The same unit can be converted to function as a Fine Filter, ideal for controlling oil contamination levels of particles, water and degradation products (oxidation resin/sludge, varnish).


Application: systems to 10,000 Litres


Filter Separator mode:

• Hydraulic oils (e.g., reservoirs)

• Boiler feed pumps

• Steam turbine lubrication oils

• Gearboxes with potential water ingress (e.g., wet crushers or marine thrusters)

• Lubrication oil for industrial and marine applications where water ingress is a recurrent problem


Fine Filter mode:

• Hydraulic systems (e.g., test benches, power packs for cranes, presses etc.)

• Lubrication systems (e.g., for bearings, gears etc.)

• Marine diesel engine lubrication

• Quench works and similar industrial and marine applications



Extends the lifetime of both oil and system | Prevents uncontrolled breakdowns | Reduces maintenance costs | Easy to connect and operate
